About local backup of a snapshot
A snapshot can be backed up to any NetBackup storage device. A Fibre Channel network or SAN is not required. The following diagram shows a network configuration sufficient for backing up a snapshot on the primary client (sometimes referred to as a "local" snapshot backup). The network configuration is identical to the configuration for normal NetBackup (no snapshot).
The figure shows the following phases in the local backup process:
Phase | Action |
|---|---|
Phase 1 | NetBackup primary server tells the client to create the snapshot of the primary data. |
Phase 2 | Client reads the snapshot, formats a backup image reflecting the primary data, and writes the image to the media server. |
Phase 3 | Media server reads the backup image. |
Phase 4 | Media server writes data to local storage. |
