SnapManager initiates a backup operation at the primary host, which then contacts the remote verification server. The remote verification server then uses SnapDrive for verification and sends the results back to the primary host.
The basic steps of this process are as follows:
- The SnapManager backup with verification (or verification only) is initiated on the primary SnapManager host, which is configured to run verifications on the remote verification server.
- The primary SnapManager host contacts the remote verification server and initiates the verification job.
- The remote verification server uses SnapDrive to connect to a LUN backed by a Snapshot copy containing the databases to be verified.
- The remote verification server performs the database verification on the LUN backed by Snapshot copy.
- When the remote verification server completes the verification, it sends the results back to the primary SnapManager host.
Note: You must be careful not to schedule backup operations while a verification operation is in progress. Verification is always performed on a LUN that is backed by a Snapshot copy. If you make a Snapshot copy of the same volume while a LUN backed by Snapshot copy exists, you create a “busy Snapshot copy,” which might cause problems when you attempt to delete some Snapshot copies.
