VMware Image plug-in backup options

These backup options are available for the Avamar VMware Image plug-in.

Table 1. Backup options for Avamar VMware Image plug-in
Setting	Description
Use Changed Block Tracking (CBT) to increase performance	If selected, the VMware changed block tracking feature is used to identify areas of the virtual machine file system that have changed since the last backup and only process those changed areas during the next backup. NOTE:Changed block tracking must be enabled at the virtual machine level in order for this feature to work.
Set Annotionation Tag LastBackupStatus and LastSuccessfulBackup	If selected, enables the Avamar server to report information to the vSphere Web Client or the legacy Windows-based vSphere client about the most recent backup and most recent successful backup. When selected, the following information is displayed in the Annotation list of the vSphere Web Client: LastSuccessfulBackupStatus-com.dellemc.avamar: The date and time of the most recent successful backup. LastBackupStatus-com.dellemc.avamar: The date and time of the most recent backup, whether successful or not.
Exclude page file blocks when performing image backup on Windows VM	If selected, excludes the Windows page file (pagefile.sys) from the backup for all the partitions. It is not limited to primary partitions. NOTE:Page file exclusion is supported only for Windows Servers version 2008 R2 and above. For client versions of Windows, this option has no effect; the page file is included in backups of Windows clients, regardless of this setting. NOTE:The proxy uses NBD transport mode internally in order to read the page file blocks. After recognizing the required blocks, the available mode (hotadd/nbdssl/nbd) will be used accordingly for backup or restore operations.
Exclude deleted file blocks when performing image backup on Windows VM	If selected, excludes the deleted file blocks from the backup for all the partitions. It is not limited to primary partitions.
Exclude files with path and filter	Excludes the files with path and filter from the backup for all the partitions. It is not limited to primary partitions. Type the full path of the file or folder or the filter path of the files and folders. Separate multiple entries with a comma. To exclude files with path and filter, type the path in the following format: Start with driver letter End with "/" to exclude a folder End without "/" to exclude a file Use "" as a wildcard in the filename to exclude all files. Do not use "" as a wildcard in the file path. For example: ://.TXT is not supported. D:/folder/.txt is supported. D:/folder/* is supported.
Store backups on Data Domain system	To store the backup on a Data Domain system instead of the Avamar server, select the checkbox and then select the Data Domain system from the list. NOTE:To enable this option, add a Data Domain system to the Avamar configuration. The Avamar and Data Domain System Integration Guide provides instructions.
Encryption method to Data Domain system	Specifies the encryption method for data transfer between the client and the Data Domain system during the backup. As of Avamar release 7.5, the only supported encryption method is "high."

Max times to retry snapshot delete	The maximum number of times that a snapshot delete operations should be attempted.
Guest credentials
Username	Guest operating system user account with sufficient privileges to run scripts.
Password	Password for the guest operating system username.
Pre-snapshot Script
Script file	Full path and filename of the script that will be run before the vmdk snapshot.
Maximum script run time (minutes)	Maximum number of minutes this script is allowed to run before timing out.
Post-snapshot Script
Script file	Full path and filename of the script that will be run after the backup completes and the vmdk snapshot is removed.
Maximum script run time (minutes)	Maximum number of minutes this script is allowed to run before timing out.
Snapshot quiesce timeout
Snapshot quiesce timeout (minutes)	Maximum number of minutes to wait before the snapshot quiesce operation is considered to have failed (Windows WMware Image plug-in only)
Microsoft SQL Server authentication

Application Authentication	Uses the SQL Server Username and SQL Server Password to log in to the SQL server.
Microsoft SQL Server post action
Post Action Timeout (minutes)	Maximum number of minutes to wait before post-action operations are considered to have failed. Default is 900 seconds.
Post Action Type of MSSQL	The type of post-action operation to perform. The only available option is LOG Truncation, which performs log truncation after the backup has been performed. When backing up a single VM, all disks of the VM must be selected or log truncation will not occur.
Quota limit per backup
Soft limit size (MBs)	Indicates the soft limit size of a backup. If the size of the backup source exceeds the soft limit, the backup succeeds with a warning. If you provide both the soft and hard limit size, ensure that the soft limit size is smaller than the hard limit size.
Hard limit size (MBs)	Indicates the hard limit size of a backup. If the size of the backup source exceeds the hard limit, the backup fails.
