Accelerator forced rescan for virtual machines (schedule attribute)
Accelerator forced rescan helps to prevent corrupt backup image issues by manually executing the ForcedRescan command. When Accelerator forced rescan is used, all the data on the virtual machine is backed up. This backup is similar to the first Accelerator backup for a policy. For the forced rescan job, the optimization percentage for Accelerator is 0. The duration of the backup is similar to a non-Accelerator full backup.
Force rescan enhances safety, and establishes a baseline for the next Accelerator backup. This feature protects against any potential damage like failure of checksum verification on the data in the staging area.
Recommendations for using forced rescan:
Do not trigger force rescan for the VMs which are turned off.
If the storage location memory is full, you can see a notification in the UI. Initiate the force rescan only when sufficient memory is available at the storage location.
NetBackup creates a schedule named 'ForcedRescan' for every protected VM. To manually trigger the backup with force rescan execute the following command in the command prompt or the Linux terminal:
bpbackup -i -p <policy_name> -s ForcedRescan
For example, bpbackup -i -p msdp_10mins_FRS+5d990ab5-f791-474f-885a-ae0c30f31c98 -s ForcedRescan
You can obtain the policy name from web UI from the relevant protection plan.
