About recovering the MSDP catalog
The following are the recovery options for the NetBackup MSDP catalog:
Table: MSDP catalog backup recovery options
Recovery option | Description |
---|---|
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. |
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. |
Caution:
You must determine if your situation is severe enough to recover the catalog. Veritas recommends that you contact your Veritas Support representative before you restore or recover the MSDP catalog. The Support representative can help you determine if you need to recover the catalog or if other solutions are available.
