Backup and Restore LDT on NFS GuardPoints

Native backup capabilities in an NAS server is the recommended method for backing up and restoring GuardPoints on a NAS share. You may also backup or restore GuardPoints on NAS shares on the host designated as the primary host for an LDT GuardPoint Group, as described earlier.

Backup LDT on NFS GuardPoint

Backups of the NAS servers are remote from an LDT perspective.

It is extremely important that while you are backing up the NAS server:

• LDT is not performing data transformation in the GuardPoint

• No client is modifying data in the GuardPoint

This rule applies for:

• Initial data transformation

• Automatic or manual key rotation

• Backups of an entire GuardPoint, or any subset of files within a GuardPoint namespace.

Restore LDT on NFS GuardPoints

All clients must have their GuardPoints disabled prior to restoring the backup on the NAS server. GuardPoints is required because LDT over NFS clients are unaware of changes being performed to the files, and LDT metadata for the files, on the NAS server.
