With Tivoli® Storage FlashCopy® Manager software you can configure and manage storage management policies for backups.
Policy definitions are only applicable when you use a stand-alone configuration. If Tivoli Storage FlashCopy Manager is configured to use the Tivoli Storage Manager server, the policy definitions are defined on the Tivoli Storage Manager server. VSS policy bindings are still managed locally.
Tivoli Storage FlashCopy Manager uses a policy to determine how backups are retained. With Tivoli Storage FlashCopy Manager, you can create, change, and view policies, and set binding policy statements to manage your backups.
Backup retention on local shadow volumes is dictated by version and time-based policies. Sufficient local storage space must be available on local shadow volumes for a VSS backup strategy to be successful. Ensure that there is enough available storage space that is assigned to the volumes to accommodate your backup operations. The shadow copy volume that is the storage destination of a snapshot must have sufficient space for the snapshot.
Environment and storage resources also impact how many backup versions are maintained on local shadow volumes. The amount of space that is required is dependent on the VSS provider that is used.
