Restore from a shadow copy

If NetBackup detects corruption in the MSDP catalog, the Deduplication Manager restores the catalog automatically from the most recent shadow copy. The automatic restore process also plays a transaction log so that the recovered MSDP catalog is current.

Although the shadow copy restore process is automatic, a restore procedure is available if you need to recover from a shadow copy manually.

See About the MSDP shadow catalog.

Recover from a backup

If you configured an MSDP catalog backup policy and a valid backup exists, you can recover the catalog from a backup. As a general rule, you should only attempt to recover the MSDP catalog from a backup if you have no alternatives. As an example: A hardware problem or a software problem results in the complete loss of the MSDP catalog and the shadow copies.

The greatest chance for a successful outcome when you recover the MSDP catalog from a backup is when the recovery is guided. An unsuccessful outcome may cause data loss. For the customers who need to recover the MSDP catalog, Veritas wants to guide them through the process. Therefore, to recover the MSDP catalog from a backup, contact your Veritas support representative. You can refer the support representative to Knowledge Base Article 000047346, which contains the recovery instructions.
