Things to consider before you use the instant rollback feature
Note the following about the instant roll back virtual machines feature:
This feature is supported with backup copies. These copies are created with protection plans (web UI) or classic policies (NetBackup Administration Console).
This feature is supported for NetBackup Appliance, NetBackup Virtual Appliance, and Build Your Own (BYO) server.
This feature does not support backups of VMs that have independent disks. VMware does not support snapshots of independent disks in a VM, either persistent disks or non-persistent disks. As a result, independent disks are not backed up.
For more information, see the following:
This feature does not support VMs that have the disks that were excluded from the backup. In the NetBackup Administration Console, on the policy's Exclude Disks tab, select . Or, in the NetBackup web UI, in the protection plan, clear the check box.
This feature does not support VMs that have a disk in raw device-mapping mode (RDM).
This feature lets you select a maximum of 100 VMs for rollback at a time. If you select more than 100 VMs the option is not displayed.
For example, if you want to rollback 180 VMs, you need create two rollback requests for the same job. One for 100 VMs and the second for 80 VMs.
In this feature, one instant rollback VM requires one livemount. Each livemount can be retained for one day. So the number of VMs that can support roll back depend on the total number of livemounts available. By default, the livemounts value is set to 200.
You can change this default value from the following location:
storage path/spws/etc/spws.cfg
