Chapter 1: Introducing the Nasuni Filer

Nasuni’s Enterprise Storage Services deliver an advanced storage solution using a cloud infrastructure. The core technology is a next-generation storage controller – the Nasuni Filer – that offers the security and performance of traditional storage, while adding unlimited scalability, automatic offsite protection, and global multi-site access to files. The Nasuni system is managed through a single, small-footprint point of control within the enterprise’s data center.

The Nasuni Filer is an on-premises storage device supporting NFS, CIFS, FTP/SFTP, iSCSI, and HTTP/ REST protocols. The Nasuni Filer is fully integrated with Active Directory, Distributed File System (DFS), and Windows Previous Versions. It includes a high-performance cache and takes periodic snapshots that enable file-level restores. The Nasuni Filer is available as a virtual appliance, as a hardware appliance, and as a Microsoft Azure and Amazon EC2 virtual appliance. Its reach and capacity far exceed those of a traditional controller, however, because it does not rely only on memory and local disk to manage its data: it has the entire capacity of the cloud at its disposal. All data is deduplicated, compressed, and encrypted before storage.

Multi-site access enables organizations with several locations to work on a single set of shared data. Nasuni’s architecture allows multiple storage controllers to have live access to the same volume of data. Organizations benefit by having a simple, safe, and secure way to share data across any number of sites. Nasuni’s multi-site access enables capabilities that include:

• Secure data distribution to remote office/branch office (ROBO). • Remote offices forwarding data to a central point.

• Two-way synchronized read-write.

Multi-site access does away with cumbersome replication schemes and slow WAN optimizers.

Nasuni Filer

Nasuni’s Enterprise Storage Services are delivered through the Nasuni Filer, a storage controller that runs in your data center and provides primary storage with built-in backup, offsite protection, and multi-site access. With your Nasuni Filer, you manage your volumes and performance using the Web-based Nasuni Filer user interface.

(16)

Key Terms

Key Terms

The following terms are helpful in understanding the Nasuni Filer:

• Nasuni Filer: The storage controller in your data center that integrates with your infrastructure via CIFS, NFS, iSCSI, FTP/SFTP, or HTTPS/REST protocols. The Nasuni Filer can be mapped as a network drive.

• Nasuni Filer user interface: The Web-based graphical user interface with which you configure and manage the Nasuni Filer. The Nasuni Filer user interface is accessible with supported Web browsers including Mozilla Firefox, Internet Explorer, Safari, and Google Chrome.

• Nasuni Management Console (NMC): The Web-accessible appliance with which you can configure and manage multiple Nasuni Filers. The Nasuni Management Console is accessible with supported Web browsers including Mozilla Firefox, Internet Explorer, Apple Safari, and Google Chrome.

• Cloud storage: Internet-based, highly protected, unlimited storage.

• Volume: A set of files and directories (CIFS, NFS, and FTP/SFTP) or blocks of data (iSCSI). • Share/export: An access point to a folder on a volume that can be shared or exported on your

network. Access to a CIFS share can be customized on a user-level or group-level basis. You can create many shares or exports on a volume, for different purposes or audiences.

• Cache: The local storage of the Nasuni Filer. All data and metadata that is accessed regularly is kept locally in the cache. If requested data is not locally resident, it is staged into the cache and provided for the request.

• Snapshot: A snapshot is a complete picture of your volume at a specific point in time.

Snapshots offer data protection by enabling you to recover data deleted in error or to restore an entire file system. After a snapshot has been taken and is sent to cloud storage, it is not

possible to modify that snapshot. Also, see “Glossary” on page 386.

About File Systems

About File Systems

File system data and metadata are stored locally on the Nasuni Filer. However, permanent storage is in the form of cloud-based storage. Changes in files are sent to cloud storage by the Nasuni Filer, at times that your snapshot schedule specifies and at rates specified by your Quality of Service (inbound and outbound bandwidth) setting. On volumes with global file locking enabled, global locking provides file synchronization independently of the snapshot and synchronization processing. You can also manually initiate snapshots.

Note: The Nasuni Filer supports Windows, UNIX, and Linux clients. Client capabilities and behavior vary, depending on the client type and version of the client operating system. File system metadata includes:

• Standard access control list (ACL) and file system metadata, such as permissions and file size. • Version history of operations on files, including creating, updating, deleting, and moving files. • Location of file versions.

Data is versioned with the ability to go back to a point in time at the volume, directory, and file levels. Volume metadata includes:

• Version history of operations on the volume, including creating, updating, deleting, and moving the volume. When and by whom the volume was instantiated.

• Protocol: CIFS, NFS, FTP/SFTP, iSCSI, and HTTP/REST. • Encryption settings.

About the Cache

When you first launch the Nasuni Filer, the local cache is empty, although the Cache display on the Home page might reflect the data required to set up the file system. Afterwards, any data written to a volume is staged in the local cache. After one hour, the first snapshot occurs. (To take a snapshot sooner, click “Take snapshot now” on the Volumes page.) Each file in the cache is deduplicated, compressed, encrypted, and sent to cloud storage. This is the only time that the entire cache is sent to cloud storage. Subsequent snapshots include only the changes between the original version of the files and the most recent version of the files.

The cache continuously tracks “recently changed” data, such as files created or changed since the last snapshot. New data that has been saved to the cache, but has not yet been protected in cloud storage, is classified as “new data in cache not yet protected”.

The most recently used files remain in the cache. Saved data that was written once and rarely used afterwards is eventually removed (“evicted”) from the cache to free up space for data that is accessed more frequently. If one of these evicted files is later requested for reads or writes, the Nasuni Filer retrieves the file from cloud storage and puts it back into the local cache automatically.

(19)

Trial Mode

Cache Capacity

The cache keeps local copies of working files for fast access to frequently accessed data. When the cache starts to become full, it first removes (“evicts”) files that have already been sent to cloud storage and are rarely accessed, using a least-recently-used (LRU) algorithm. If more space is necessary, a snapshot is performed to protect more data in cloud storage, after which the protected data can then be evicted from the cache. As a result, the cache rarely reaches full capacity. After a snapshot is complete, the cache status displays 0% “new data in cache not yet protected”, until you change data or create new data.

You can continue to use your system normally during each snapshot. The size and status of the cache is displayed on the Home page.

Figure 1-1: Cache status.

As a default, the Nasuni Filer tries to keep about 30 percent of the cache free to accept new data. Pinning volumes or folders in the cache or manually changing the cache settings can affect the percentage of the cache that is free to accept new data.

Trial Mode

You are entitled to a free, 14-day, fully-functional evaluation of the Nasuni Filer. After your free trial period has expired, you must upgrade to continue using the product.

If the Nasuni Filer is in Trial mode, the Trial Mode indicator appears on the bottom of each page.

Figure 1-2: Trial Mode indicator.

Clicking this indicator opens the Subscription Status page, which includes details about how much time remains in the Trial period. See “Subscription Status” on page 338.

When your trial period ends, you cannot send any data to or receive data from cloud storage until you upgrade your account. Local data in the cache is accessible. However, if you do not upgrade your account within 30 days after the trial period ends, your data might be deleted. See the Nasuni Filer Terms of Service and License Agreement for details at http://www.nasuni.com/sub/eula/.

Chapter 2: Starting Out

This chapter includes these sections:

• An overview of some of the tasks that you can perform with the Nasuni Filer, along with links to further information.

Note: If this Nasuni Filer is under the control of the Nasuni Management Console, for many of these tasks, you use the Nasuni Management Console to view information or perform actions. For details, see the Nasuni Management Console Guide.

• A list of available actions on the Nasuni Filer user interface and the Nasuni Management Console.

Starting with the Nasuni Filer

Installing the Nasuni Filer

The Nasuni Filer is already installed on Nasuni hardware appliances.

Installing and configuring the Nasuni Filer on a virtual platform is a simple and straightforward process. • First, download and install the software on your virtual platform. See the Nasuni Filer

Virtualization Getting Started Guide. To install on the Microsoft Azure virtual platform, see Nasuni Filer Virtualization Azure Getting Started Guide. To install on the Amazon EC2 virtual platform, see Nasuni Filer Virtualization EC2 Getting Started Guide.

• Run the Install Wizard, including entering the Serial Number and Authorization Code, found under the Account section of www.nasuni.com, or on the Account Status page of the Nasuni Management Console. See the Nasuni Filer Initial Configuration Guide.

• A best practice for Nasuni Filers is to join an Active Directory domain as soon as installation is complete. For details, see “Joining a Nasuni Filer (that has not previously joined any domain) to

a domain” on page 272.

Disaster recovery

You can perform the disaster recovery procedure for a genuine emergency, or when moving the Nasuni Filer to another location. See “Disaster Recovery” on page 376.

(21)

Starting with the Nasuni Filer

Creating new volumes

You use volumes to manage data. If you do not already have a volume set up, you can create a new volume.

Note: If this Nasuni Filer is under the control of the Nasuni Management Console, you use the Nasuni Management Console to perform this task.

• Before creating a new volume, ensure that you have the encryption keys you would like to use. Nasuni recommends creating and uploading your own encryption keys (“Adding (Importing or

Uploading) Encryption Keys” on page 289). Otherwise, you can specify generating a new

encryption key when you create the new volume. Nasuni also recommends safeguarding your encryption keys yourself. You can download generated encryption keys for safeguarding

(“Downloading (Exporting) Generated Encryption Keys” on page 290). Alternatively, you can

escrow encryption keys with Nasuni (“Escrowing Encryption Keys with Nasuni” on page 291). • To create a new volume on a Nasuni Filer, see “Adding a Volume” on page 46.

• You can create CIFS shares (“Adding a New CIFS Share to a Volume” on page 101), NFS exports (“Adding an NFS Export to a Volume” on page 117), or FTP/SFTP directories (“Adding

FTP directories for a volume” on page 127) for users to access. If you created a CIFS share,

NFS export, or FTP/SFTP directory automatically when you created a new volume, you can check and edit the settings for CIFS shares (“Editing a CIFS Share” on page 113), NFS exports

(“Editing an NFS Export” on page 120), or FTP/SFTP directories (“Editing FTP directories” on

page 132).

Managing the Nasuni Filer

You have many options for configuring the Nasuni Filer.

• You can configure the Nasuni Filer to automatically download and install software updates. To prevent automatic software updates from occurring at inconvenient times, you can specify the days and times for automatic software updates to occur, or prevent automatic software updates entirely. See “Automatic Software Updates” on page 332.

Alternatively, you can manually update the Nasuni Filer software. See “Software Updates” on

page 340.

Note: If this Nasuni Filer is under the control of the Nasuni Management Console, you use the Nasuni Management Console to perform this task.

• You can view the status and expiration date of your subscription. See “Subscription Status” on

page 338. You can also refresh your subscription license. See “Refreshing Subscription

(22)

Managing data

• You can configure email alerts, which are sent to your email account from the Nasuni Filer. You can select various types of alerts to receive. See “Email Settings” on page 247.

Managing data

Providing data access to users

You can define the specific data that users can access. You can also define which users can access data.

• You can create a CIFS share, an NFS export, or an FTP/SFTP directory for each directory in the volume that you want to provide access to. You can create many CIFS shares, NFS exports, or FTP/SFTP directories on a volume. See “Adding a New CIFS Share to a Volume” on page 101,

“Adding an NFS Export to a Volume” on page 117, and “Adding FTP directories for a volume”

on page 127. If you created a CIFS share, NFS export, or FTP/SFTP directory automatically

when you created a new volume, you can check and edit the settings for CIFS shares (“Editing a

CIFS Share” on page 113), NFS exports (“Editing an NFS Export” on page 120), or FTP/SFTP

directories (“Editing FTP directories” on page 132).

For each CIFS share, NFS export, or FTP/SFTP directory, you can define which volume and which directory within the volume to share, export, or FTP. You can specify Read-Only access. You can limit which hosts can access the CIFS share, NFS export, or FTP/SFTP directory. For CIFS shares with Active Directory security, you can define groups that can access the CIFS share, and specify Read-Write, or Read-Only, or Deny access for each group. You can add users to or remove users from these groups. You can also specify individual users that can access the CIFS share, and specify Read-Write, Read-Only, or Deny access for each individual user.

You can map network drives to CIFS shares in Windows, access iSCSI volumes in Windows, and mount CIFS shares or NFS exports in Linux or UNIX. You can access FTP/SFTP directories using the FTP/SFTP protocol.

You can also define multiple protocols to access data using CIFS, NFS, and FTP/SFTP.

• You can enable Web Access to CIFS shares and NFS exports. This allows users to access data using any supported Web browser. See “Web Access” on page 150.

• You can enable and install the Nasuni Desktop Client for CIFS shares. This allows users to access data using a simple interface on their own desktop. See “Nasuni Desktop Client” on

page 167.

• You can enable Mobile Access to CIFS shares. This enables users to access data using mobile devices, including iOS-based devices (such as iPhone and iPad) and Android phones. See

“Nasuni Mobile Access” on page 157.

You can specify details of the Mobile Service, such as adding another port for Mobile Access, limiting how long users remain authenticated on mobile devices, limiting users to only one

(23)

Managing data

mobile device, and limiting the types of mobile devices that can use Mobile Access. See

“Mobile Access: Configuring” on page 236.

You can enable, disable, and delete individual licenses for the Mobile Access service. See

“Mobile Access: Managing access by mobile devices” on page 237.

Sharing data between Nasuni Filers

You share data between Nasuni Filers by using volumes. If you do not already have a volume set up on the source Nasuni Filer, you can create a new volume (“Adding a Volume” on page 46).

• Volumes are not shared by default. First, you need to enable Remote Access on the source volume. You can then specify Read/Write or Read Only access for the destination Nasuni Filers.

See “Remote Access” on page 83.

• After the source volume has Remote Access enabled, you connect the destination Nasuni Filers to the source volume. See “Connecting to a Remote Volume” on page 51.

• End users access the data through CIFS shares, NFS exports, or FTP/SFTP directories of the destination volume. You define CIFS shares (“Adding a New CIFS Share to a Volume” on

page 101), NFS exports (“Adding an NFS Export to a Volume” on page 117), or FTP/SFTP

directories (“Adding FTP directories for a volume” on page 127) on the destination volume for users to access. If you created a CIFS share, NFS export, or FTP/SFTP directory automatically when you created a new volume, you can check and edit the settings for CIFS shares (“Editing a

CIFS Share” on page 113), NFS exports (“Editing an NFS Export” on page 120), or FTP/SFTP

directories (“Editing FTP directories” on page 132).

• You can schedule when The Nasuni service syncs (synchronizes) the data between Nasuni Filers. See “Configuring a Sync Schedule” on page 171.

Adding data to volumes

There are several ways to add data to volumes.

• The best way to load your data to a volume is by using the Data Migration Service. This feature supports multiple sources and targets for migrations using CIFS or NFS protocols. See

“Configure” on page 200.

• You can share data from other Nasuni Filers as described in “Sharing data between Nasuni

(24)

Managing data

• You can define Mobile Access to CIFS shares. This enables users to add data to volumes using mobile devices, including iOS-based devices (such as iPhone and iPad) and Android phones.

See “Nasuni Mobile Access” on page 157.

Note: If this Nasuni Filer is under the control of the Nasuni Management Console, you use the Nasuni Management Console to perform this task.

• You can enable and install the Nasuni Desktop Client for CIFS shares. This allows users to access data using a simple interface on their own desktop. See “Nasuni Desktop Client” on

page 167.

• You can map network drives to CIFS shares in Windows (see “Mapping a Windows network

drive to a CIFS share” on page 143), access iSCSI volumes in Windows (see “Accessing an

iSCSI volume in Windows” on page 144), and mount CIFS shares or NFS exports in Linux or

UNIX (see “Mounting a CIFS share in Linux or UNIX” on page 147 and “Mounting an NFS export

in Linux or UNIX” on page 149). This enables users to add data to volumes using the file

management capabilities of Windows, Linux, and UNIX operating systems.

• You can access FTP/SFTP directories using the FTP/SFTP protocol. See “Accessing data using

the FTP/SFTP protocol” on page 141.

Protecting data

A snapshot is a complete picture of the files and folders in your file system at a specific point in time. Snapshots offer data protection by enabling you to recover past versions of a file or to restore an entire file system. You can select when and how frequently to perform snapshots. For example, you can configure snapshots to occur only during off-hours when network usage is low.

• You can schedule snapshots for whenever suits your system best. See “Snapshot Scheduling”

on page 88.

• You can also take manual snapshots at any time. See “Take a Snapshot Now” on page 54. • For compliance purposes or your own best practices, you can specify to delete older snapshots

from cloud storage, based on a configured snapshot retention policy for a specific volume. See

“Snapshot Retention” on page 94.

• You can restore a file or folder (for a CIFS or NFS volume, or FTP/SFTP directory) or an entire volume (for an iSCSI volume) from any location. See “Searching for a Folder or File by Name” on

page 182 and “Restoring Volume, Folder, or Files” on page 192.

Managing volumes

The Nasuni Filer offers many options for managing volumes.

• Volumes should have names that describe what data they contain and that users recognize. You can change the name of a volume. See “Volume Status” on page 40.

• You can change the name of an iSCSI target. See “Volume properties page for iSCSI volumes”

(25)

Security

• You can monitor file statistics. See “File Types in snapshots” on page 370, “File Sizes in

snapshots” on page 370, and “Data Growth Chart” on page 34.

• For CIFS and NFS volumes and FTP/SFTP directories, the volume quota (maximum capacity) enables you to limit the amount of storage space for a volume, including snapshots, which helps you to control your storage costs. You can change the volume quota. See “Changing the

Volume Quota” on page 65.

The Nasuni Filer can also send email reports to administrators or to users about which

directories are near or over their quota. For details about setting a directory quota, see “Setting

Quota or Rule” on page 186.

• You can delete volumes that are no longer needed. See “Deleting a Volume” on page 98.

Security

Handling encryption keys

Encryption keys are used to encrypt your data in cloud storage. You can use the Nasuni Filer to manage encryption keys in several ways.

• You can view encryption keys and their settings. See “Encryption Key Management” on

page 287.

• Nasuni recommends creating and uploading your own encryption keys. You can upload encryption keys to the Nasuni Filer. See “Adding (Importing or Uploading) Encryption Keys” on

page 289.

Alternatively, you can specify generating a new encryption key when you create a new volume. • The next step is to add specific encryption keys to specific volumes. See “Adding Encryption

Keys to a Volume” on page 81.

The next step is to enable (or disable) specific encryption keys for specific volumes. See

“Enabling Encryption Keys” on page 77 or “Disabling Encryption Keys” on page 79.

• Nasuni recommends safeguarding your encryption keys yourself. You can download generated encryption keys for safeguarding. See “Downloading (Exporting) Generated Encryption Keys”

on page 290.

(26)

Changing performance

Role-based access control

Rather than managing the permissions for performing tasks for each individual user, it is simpler to create groups that have specific combinations of permissions, and then assign users to the appropriate groups. You can define users and groups of users, and then assign specific permissions to each group. • To control who has permission to perform actions on the Nasuni Filer, you can define users and

groups of users, then assign specific permissions. See “Users and Groups” on page 315. • To control who has permission to access CIFS shares that have Active Directory security, you

can define users and groups of users, then assign specific permissions. See “Editing a CIFS

Share” on page 113.

SSL certificates

The user interface of the Nasuni Filer is Web-based. In order to secure this Web site, SSL certificates or self-signed certificates are used. You can view or add SSL certificates or a self-signed certificate that you can use when accessing the Nasuni Filer user interface. See “SSL Certificates” on page 301.

Antivirus protection

Nasuni offers the option of protecting data with antivirus scanning, and review of files flagged for violations.

• You can enable or disable the Antivirus Service. See “Antivirus Service” on page 69. • You can review antivirus violations. See “Reviewing Infected Files” on page 71.

Firewall protection

You can limit which network hosts are allowed to connect to the Nasuni Filer user interface and the Nasuni Support SSH port, which provides firewall protection. See “Firewall” on page 294.

Changing performance

There are a number of ways that you can change the performance of the system.

• The Quality of Service (QoS) settings specify the inbound and outbound bandwidth for moving data to and from the Nasuni Filer. Snapshots are slower during periods of lower bandwidth. Local user read/write operations are not affected. Limiting the bandwidth of inbound and outbound data between specific hours can help decrease network congestion. See “Quality of

(27)

Changing performance

• The cache is the local storage of the Nasuni Filer. All data and metadata that are accessed regularly are kept locally in the cache. By default, the amount of local cache space reserved for new writes is managed automatically, using an advanced algorithm to optimize cache usage. However, you can override the amount of local cache space reserved for new writes in order to suit your company’s workload. Reserving a large portion of the cache for new writes allows snapshots to complete more rapidly, but reduces the amount of data that is kept locally. Conversely, reserving a small portion of the cache for new writes allows keeping more data locally, but increases the time for completing snapshots. See “Cache Settings” on page 333. • Frequent snapshots increase the system load significantly. You can change when and how

frequently snapshots occur. See “Snapshot Scheduling” on page 88.

• Pinning a folder forces a folder to remain in the local cache at all times. This can improve performance and reduce the time necessary to return accessed data to clients. See “Pinning

Note: To exit and return to the previous page, click the x at the top of the page, or click Cancel.

2. Enter a Username (case-sensitive) and Password (case-sensitive) that has permission to perform this operation.

3. Select one of the following options:

• Perform snapshot before shutting down: The Nasuni Filer performs a snapshot before shutting down. This ensures that data is fully protected in cloud storage before shutting down. However, this process can take considerable time, depending on the size of the

(42)

• Shut down immediately: (Default) Shuts down the Nasuni Filer without performing a snapshot. Data that has not already been captured by a snapshot is not protected in cloud storage. However, data in the cache is not lost. A message on the Nasuni Filer Home page notifies you that the Nasuni Filer is shutting down. If you change your mind, you have 60 seconds to cancel the shutdown.

Tip: On the Windows Azure virtual platform, virtual machines that have been shut down continue to incur compute charges. To avoid these charges, use the Windows Azure Management Portal at https://manage.windowsazure.com/ to stop or delete the virtual machines.

• Reboot immediately: Reboots the Nasuni Filer without performing a snapshot. In a few moments, the console reloads and the Nasuni Filer Home page re-appears.

Note: On a high availability hardware appliance Nasuni Filer, rebooting this node triggers a failover to the other high availability node, if that node is online.

• Reboot and perform a filesystem check: Reboots the Nasuni Filer and forces a file system check (fsck) on the cache disk when the Nasuni Filer reboots.

Note: On a high availability hardware appliance Nasuni Filer, rebooting this node triggers a failover to the other high availability node, if that node is online.

Note: File system checks (using fsck) are necessary at least every six months. However, a file system check might take hours to complete (depending on the size of the cache) and might interfere with normal operations. To determine if a file system check is actually necessary, the Nasuni Filer periodically performs a background test. If this background test determines that a file system check is not necessary, the next file system check is postponed for another six months. However, if the background test determines that a file system check is necessary, you receive an alert suggesting that you perform a reboot and a file system check. This allows you to select a time for performing a reboot with a file system check that does not interfere with normal operations.

Even if you don’t receive such an alert, you can choose to perform a reboot with a file system check, for example, if you want to proactively verify the integrity of the cache, such as after an unexpected power loss.

Tip: If your Nasuni Filer is a Nasuni Filer hardware appliance or runs in a VMware ESXi environment or Microsoft Hyper-V environment, you can also force a file system check (fsck) by holding down the Shift key during a reboot. When the file system check (fsck) is done, the usual processing continues.

4. Click Shutdown.

The message “The Nasuni Filer is shutting down.” appears.

5. To stop the shutdown, click the hyperlink marked “click here” to cancel the shutdown. You have 60 seconds to cancel the shutdown.

The message “Shutdown cancelled at user request.” appears. The shutdown stops.
