About the MSDP catalog backup policy
Veritas recommends that you protect the MSDP catalog by backing it up. A NetBackup catalog backup does not include the MSDP catalog. The NetBackup Deduplication Catalog Policy Administration and the Catalog disaster recovery utility (the drcontrol utility) configure a backup policy for the MSDP catalog. The policy also includes other important MSDP configuration information.
The MSDP catalog backups provide the second tier of catalog protection. The catalog backups are available if the shadow copies are not available or corrupt.
The following are the attributes for the catalog backup policy that the drcontrol utility creates:
|
Schedule |
Weekly and daily . |
|
Backup window |
6:00 A.M. to 6:00 P.M. |
|
Retention |
2 weeks |
|
Backup selection |
The following are the default catalog paths. UNIX: /database_path/databases/catalogshadow /storage_path/etc /database_path/databases/spa /storage_path/var /usr/openv/lib/ost-plugins/pd.conf /usr/openv/lib/ost-plugins/mtstrm.conf /database_path/databases/datacheck Windows: database_path\databases\catalogshadow storage_path\etc storage_path\var install_path\Veritas\NetBackup\bin\ost-plugins\pd.conf install_path\Veritas\NetBackup\bin\ost-plugins\mtstrm.conf database_path\databases\spa database_path\databases\datacheck By default, NetBackup uses the same path for the storage and the catalog; the database_path and the storage_path are the same. If you configure a separate path for the deduplication database, the paths are different. Regardless, the drcontrol utility captures the correct paths for the catalog backup selections. |
You should consider the following items carefully before you configure an MSDP catalog backup:
Do not use the as the destination for the catalog backups. Recovery of the MSDP catalog from its is impossible.
Use a storage unit that is attached to a NetBackup host other than the MSDP storage server.
Use a separate MSDP catalog backup policy for each MSDP storage server.
The drcontrol utility does not verify that the backup selections are the same for multiple storage servers. If the backup policy includes more than one MSDP storage server, the backup selection is the union of the backup selections for each host.
You cannot use one policy to protect MSDP storage servers on both UNIX hosts and Windows hosts.
UNIX MSDP storage servers require a Standard backup policy and Windows MSDP storage servers require an MS-Windows policy.
