Configuring the snapshot backup type
1. Open the Authentication Console from the Start→Programs→HP→HP StoreVirtual menu.
2. Select Action→Preferences from the menu bar.
3. Specify the snapshot backup type.
• Full Backup – All files, regardless of whether they have been marked as backed up or
not, are saved. This is the default backup type and schema, and all writers support it.
• Incremental Backup – Files created or changed since the last full or incremental backup
are saved. Files are marked as having been backed up. A requester can implement this
type of backup on a particular writer only if it supports the VSS_BS_INCREMENTAL
schema. If a requester's backup type is VSS_BT_INCREMENTAL and a particular writer's
backup schema does not support that sort of backup, the requester will always perform
a full backup (VSS_BT_FULL) on that writer's data.
• Differential Backup – Files created or changed since the last full backup are saved. Files
are not marked as having been backed up. A requester can implement this type of backup
on a particular writer only if it supports the VSS_BS_DIFFERENTIAL schema. If a requester's
backup type is VSS_BT_DIFFERENTIAL and a particular writer's backup schema does not
support that sort of backup, the requester will always perform a full backup (VSS_BT_FULL)
on that writer's data.
• Copy Backup With No History Update – Files on disk will be copied to a backup medium
regardless of the state of each file's backup history, and the backup history will not be
updated. A requester can implement this type of backup on a particular writer only if it
supports the VSS_BS_COPY schema. If a requester's backup type is VSS_BT_COPY and
