Other features in Vembu NetworkBackup
Microsoft Exchange Server Backup:
Vembu NetworkBackup supports backup of Microsoft Exchange servers using Exchange Server Plugin. Microsoft Exchange Server Plugin is an efficient way of backing up Microsoft Exchange servers. The Microsoft Exchange Server Plugin backup uses the VSS API [Volume Shadow Copy Services] for all Microsoft
Exchange Server versions. Vembu NetworkBackup allows direct upload without dumping the data locally.
Microsoft Exchange Mailbox Backup:

Microsoft SQL Server Backup:
Vembu NetworkBackup supports backup of Microsoft SQL servers using SQL Server Plugin. SQL Server Plugin is a flexible and efficient option while backing up
Microsoft SQL servers. Vembu NetworkBackup's SQL Server plugin uses VDI API to backup database(s) and then uploads the locally dumped file to the backup server.
Microsoft SharePoint Backup:
Vembu NetworkBackup supports a site-collection level backup of Microsoft SharePoint Servers. Vembu NetworkBackup uses internal SharePoint dump utility(STSADM.EXE, offering a full fidelity backup) to dump the SharePoint
site-collection(s) and then uploads the locally dumped file(s) to the backup server. During a full backup, the entire site-collection(s) is dumped locally and then the dumped file is transferred to the backup server. And during an incremental backup, the entire site-collection(s) is dumped locally and only the modified content since the previous full backup is transferred to the backup server.
Microsoft Outlook Backup:
Vembu NetworkBackup's Microsoft Outlook Plugin backs up emails configured in the Outlook profile. All the emails and rules at folder level are backed up with this plugin Vembu NetworkBackup should be running in the machine where Microsoft Outlook is installed to create Microsoft Outlook backups.
MySQL Database Backups:
Vembu NetworkBackup supports backup MySQL database(s).
File Backup:
VembuHIVE™ :
VembuHIVE is our proprietary, patent-pending technology for next-generation data backup, recovery, sharing, and collaboration. One of the key components of this technology is the Vembu HIVE File System (VHFS) - a file system residing over native file systems with built-in version control, security, encryption, and error correction. The inherent flexibility that allows VHFS to host any file system is the key to its ability to seamlessly support a wide range of complex restore use-cases in Vembu NetworkBackup.
Rebuild Vembu NetworkBackup Server After a Disaster:
There are endless reasons why the OS can get corrupted, resulting in quite the disaster if you have not backed up your server machine. Vembu NetworkBackup has the ability to reconstruct all the backup metadata information from storage repositories and restore the entire backup server setup to its previous state.
Backup Server Clustering:
Vembu NetworkBackup Server can be setup as a cluster to manage huge loads and will ensure high availability of the Vembu NetworkBackup server. Backup/restore requests from the Vembu NetworkBackup clients are directed to the different nodes in a round-robin fashion. The first backup request is directed to the first node, the second request to the second node and so on. This load balancing algorithm needs centralized backup data storage solution such as SAN, NAS and MySQL and MongoDB should be installed in a separate machine. It supports the dynamica taking down and adding of nodes to the cluster on-the-fly.
Vembu Universal Explorer:
Vembu Universal Explorer is a separate application which is used to perform granular level recovery from Microsoft Applications such as, Exchange, SQL, SharePoint and Active Directory.

Network
-Microsoft Exchange Server Backup
1) A Storage Group configured for backup in a backup schedule cannot be configured in a second backup schedule. If required, the first schedule has to be deleted first and thereafter configured in the second backup schedule. 2) Every time a new Database is added under a Storage Group of the Exchange
Server, then before running a differential or incremental backup, "Additional Full Backup" should be configured to run through the "Edit Exchange Server Backup" configuration.
3) When you try to restore an Exchange Database's full backup which was empty during its first full backup, then restore operation will fail. Hence you should ensure that Exchange Database is not empty when a full backup is scheduled.
Microsoft Exchange Mailbox Backup
1) It is recommended that only critical mailboxes be configured for backup using the Vembu NetworkBackup Exchange Mailbox Backup. Backing up all the mail boxes individually takes much longer time than backing up the Entire database due to limitations of the MAPI protocol.
2) Local temporary dump location configured for Exchange Server backup should not contain special characters like single quote('), double quote("), forward slash(/), backward slash(\), question(?), colon(:), asterisk(*), lesser than(<), greater than(>), pipe(|) and plus(+).
3) Please ensure that the dump location configured for the backup schedule has enough space and has valid read and write permissions to accommodate the users mailbox dump data. Also, the dump location full path should be less than 256 characters.
4) If an Exchange Mailbox name(user name) contains forward slash(/) or reverse slash(\), that mailbox might not be backed up. You will need to change the full name of that mailbox without the slash characters to get them backed up.
5) If any special character is present in any folder name (present under a user), that character will be replaced with other set of valid characters while
creating the dump file.
Microsoft SQL Backup
1) If locally dumped SQL Server database(s) backup data is deleted manually while backup is in progress, then Vembu NetworkBackup will not have the information about the manually deleted file in client machine backup report and in server backup report.
2) Local Dump path configured for SQL Server database(s) backup is not
recommended to have special characters like single quote('), double quote("), forward slash(/), backward slash(\), question(?), colon(:), asterisk(*), lesser than(<), greater than(>), pipe(|) and plus(+).
3) Please ensure that the dump location configured for the backup schedule has enough space and has valid read and write permission to accommodate the SQL Server database dump data. Also, the dump location (full path) should be less than 256 characters.
4) If Vembu NetworkBackup is killed while SQL Server database(s) backup schedule configured with multiple database(s) dump process is active, then in the next schedule locally dumped files for the database will be transferred to backup server and dump process for the remaining database(s) will be processed in the next schedule.
5) If SQL Server database(s) backup schedule is suspended while local dump is in progress, then Vembu NetworkBackup will suspend the backup after completing the current MS SQL database dump process. On resuming the same backup schedule, the dump process will not occur in the next schedule; instead, the locally dumped files will be transferred to server and an error message will be reported in backup report.
6) In multiple databases backup, if a database does not support
Differential/Transaction Log backups, then that Differential/Transaction Log backup will be skipped for that database and the error message will be reported in backup report.
7) Number of differential backups count should be greater than or equal to 2. 8) If the local dump location is configured as a FAT32 disk partition, then the
local dump file size should not exceed 4 GB as the FAT32 file system cannot hold file size more than 4 GB. In this case, Vembu NetworkBackup cannot dump the data files and the backup schedule will fail.

1) For WSS2.0/SPS2003, only the sites added from 'SharePoint Settings' page will be listed in 'Add SharePoint Site Backup' page.
2) Though the whole SharePoint Server or a whole portal site is selected for backup, only a site-collection level of backup will be done. Hence, to restore all the site-collections under a portal site, you need to restore the
site-collections under that portal site one by one using STSADM.EXE. 3) Restoring default site-collections in WSS2.0/SPS2003 is not permitted. This
attempt is strictly not recommended for WSS2.0/SPS2003.
4) A site-collection whose total size exceeds 15 GB cannot be backed up as this is being a limitation with STSADM.EXE [which Vembu NetworkBackup uses] itself. However, in such cases, you can use Vembu NetworkBackup's SQL Server backup feature for backing up the SQL databases being used by the SharePoint Server.
5) Vembu NetworkBackup should be run with Administrator privileges to list and backup SharePoint sites as STSADM.EXE can be run only with
Administrator permissions.
6) If the dump path of the SharePoint backup exceeds 255 characters, dump process will fail. Hence, make sure, you have entered a shorter dump path to enable the dump to complete successfully.
7) Restoring SharePoint 'Central Administration' may not bring the original Central Administration's whole UI and its functionalities.
Other Limitations
1. If any special character is present in any folder name (present under a user), that character will be replaced with another set of valid characters while creating the dump file.
2. The feature to resume a restore from where it left off is supported only at a file level and not at a block level. That is, if a restore failed/aborted while transferring a large file, the restore job, when it resumes, will restore that file again from the beginning.
3. The tree display in the Vembu NetworkBackup Web Console will take a long time to load if a directory contains 1000s of files/directories under it.
4. Aborting a continuous backup from the server side will only make the client begin the next schedule, making the backup start again.
5. Vembu NetworkBackup does not allow restoring the selected mailbox to an alternate Exchange Server. If needed, .PST files can be restored to alternate Exchange Server manually after restoring the files to local disk from backup server.
6. While restoring the complete contents of the selected folder to the original mailbox folder, the existing folder contents will not be deleted prior to performing the restore and restore process will append all emails to the folders. It may result in duplicate email items within the original folder. 7. Search and restoring individual mails is not supported, however restoring up
to mailbox folders is supported using Vembu NetworkBackup Exchange Mailbox plugin.
8. If you have configured Clustered Exchange Server backups, then Exchange Server name cannot be edited from the Exchange Server configuration page. If you would like to backup a different Exchange Server, then you need to delete the Exchange Server backups that have already been created.
