About reducing the size of VMware backups
This topic applies to policy configuration for NetBackup for VMware.
Table: Options for reducing the virtual machine backup size
Block level incremental backup (BLIB)
BLIB reduces the size of backups (full and incremental) by tracking block-level changes. Only the blocks that have changed since the last full or incremental are included in the backup. For incremental backups, this option applies to cumulative and to differential backups.
The VMware tab. NetBackup uses BLIB for storage optimization when the backup runs.option is enabled by default on the NetBackup policy
The first backup you run with BLIB must be a full backup.
BLIB works only with ESX 4.0 or later virtual machines at version vmx-07 or later.
If you used vSphere Client to manually create a VM snapshot and that snapshot is currently active, you may have to delete the snapshot.
Exclusion of deleted blocks.
Reduces the size of virtual machine backups by excluding any deleted sectors in the file system on the virtual machine.
To enable this option, click VMware tab.on the policy
Refer to Exclude deleted blocks in the following topic:
