VSS backup characteristics

Edit online

Backups can be stored on local shadow volumes, 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 SQL Server data by using Data Protection for SQL Server, VSS backups have the following characteristics:
  • You can run backups 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.
