VSS backup characteristics
Backups can be stored on local shadow volumes, on an IBM Storage Protect server, or at both locations. You can define different policy settings for each backup location.
Databases must have unique names. If a database has the same name as another database, but the capitalization differs, the software does not differentiate between case.
When you back up Exchange Server data by using IBM Storage Protect Snapshot,
VSS backups have the following characteristics:
- Backups provide an Exchange Server database integrity check function, but do not provide a zeroing function.
- You can run full, copy, differential and incremental backups.
- You can restore a backup to a local disk only on the same system.
When you back up SQL Server data by using IBM Storage Protect Snapshot, VSS
backups have the following characteristics:
- Backups can run in a valid Microsoft Windows Failover Clustering or Veritas Cluster Server (VCS) environment.
- You can only run full and copy-only full backups.
- You can run legacy differential and legacy log backups after you restore a full VSS backup.
- You can back up SQL server databases in an AlwaysOn Availability Group (AAG).
- To relieve resources on production servers, you can offload backups from IBM Storage Protect server storage to another system.
For custom application and file system data, data is backed up at the file system level. You can use drives and mount points. You can back up data in a valid Microsoft Windows Failover Clustering or Veritas Cluster Server (VCS) environment.
