On-Demand Client Backup dialog box

How to display it?

On the Clients tab, select one or more virtual machine clients and click Back Up Clients.

The On-Demand Client Backup dialog box lets you define various options for an on-demand backup or archive of one or more virtual machine clients.

The On-Demand Client Backup dialog box has the following features:

Name of job

A unique name for this on-demand job. This name will appear on the Status tab.

Type of job

The type of backup or archive to be performed. Choose from one of the following:

l Full machine backup

l Incremental backup

l Full machine archive

l File-level archive

Incremental backups are file-level backups when the VDDK backup technology is in use, and block-level backups when the TSM for VE technology is used.

NOTE! VDDK file-level incremental backups and archive jobs are performed ONLY for virtual machines that are running on Microsoft Windows platforms, and only with Windows versions that are supported by both VMware and TSM.

Data management class

(Optional) Define this value to apply different retention policies to selected clients. (The default management class is used by default.) The management class that you specify here controls retention of client data as well as associated control files, which are described in the next section.

Tip! The following retention policies are recommended for virtual machine data:

l Versions Data Exists (how many backup versions TSM keeps of a file that is on your local drive) — Unlimited

l Versions Data Deleted (how many backup versions TSM keeps of a file that you have deleted from your local drive) — 1

l Retain Extra Versions (how many days will elapse before the last remaining inactive backup version of a file is deleted) and Retain Only Version (how many days will elapse before all but the most recent backup version of a file that is on your local drive is deleted) — The number of days that you want to keep these copies (45, for example)

Control management class

(Optional) Define a control management class to instruct TSM to store VMware metadata information about selected virtual machine clients and disks (also referred to as control files) on disk when backing up or migrating data files to tape. During a restore, the VMB user interface (or whatever UI you are using to perform the restore) can then quickly obtain the location of the files to restore. Otherwise, the UI could be unresponsive for a period of time, while attempting to locate the files, and could even hang indefinitely if the files are on a tape that is stored in a vault, for example.

Specify a management class that uses a disk storage pool with no migration to tape. This management class affects the storage of control files only, and overrides the associated parameters specified in the data or default management class. Retention parameters specified in a control management class are ignored. Control files are expired along with virtual machine data files according to the retention policies set in the data management class or, if no data management class is defined, the default management class.

TSM server

The TSM server that will manage the files that are backed up or archived by this on-demand job. If you do not specify a TSM server, STORServer VMB assigns clients to the default TSM server.

Transport mode

Specifies the transport mode to use when moving virtual machine client data. By default, STORServer VMB uses the transport mode that is selected for each client. (Clients are configured to use Best available by default.) When changing this setting to a specific transport mode, consider the type of storage device to which the ESX/ESXi host has access.

Choose one of the following values:

l Use client value

Instructs STORServer VMB to use the transport mode defined by the virtual machine client's properties. When multiple clients are backed up, each will use its own

transport mode. This is the default selection.

l Best available

Allows STORServer VMB to choose the fastest available transport mode. Transports are tried in the following order:

SAN, HOTADD, LANSSL, LAN

l SAN

Use with a shared Fibre Channel or iSCSI device.

l LAN

Use when SAN and HOTADD are not appropriate or permitted.

l LANSSL

Same as LAN except that all data is encrypted during network transfer. If an unencrypted network channel will be used, you may also want to enable SSL certificate verification.

l HOTADD

Use with any shared or local storage device that is accessible to the ESX server hosting the backup server. The ESX/ESXi host's I/O stack is used to move data. This method is more efficient than LAN, but not as efficient as SAN.

The HOTADD transport mode is used only if the VMB software is running on a virtual machine.

Refer to theVMware documentationfor more information on transport modes and instructions for configuring roles and enabling SSL certificate verification.

Log retention period (in days)

The number of days to retain log messages related to this on-demand job. This setting

determines how long status information remains available on the Status tab. The default period is 7 days.

NOTE! STORServer VMB stores status information (logs) in its internal database.

To conserve database space, set this value to a minimum number of days.

Allow non-queisced snapshots (VDDK only)

Select this check box to allow STORServer VMB to back up selected virtual machine clients in a non-quiesced state when a quiesced snapshot is not possible. This value takes

precedence over the corresponding value specified for each client.

CAUTION! Carefully consider the use of this feature before enabling it.

Some virtual machine clients, such as those running databases, may not be good candidates for non-quiesced snapshots. If the file system is not quiescent when the snapshot is taken, the system may be captured in a transitional state, with inconsistent disk entries.
