HP Data Protector A.06.11 Integration Manual page 180

IMPORTANT:
To ensure data consistency, schedule a DPM replica synchronization before starting a
backup.
The DPM uses DPM snapshots for restore. These snapshots are not backed up. To be
able to recreate DPM snapshots you must manually schedule a backup of the replica
each time after the DPM creates a new replica.
Two backup types are supported:
• Full (for the DPM databases and replicas)
• Incremental (replicas only).
If you select unsupported backup types (Copy or Differential) when scheduling the
backup, Data Protector will abort the backup and display an error message.
Prerequisite
The MSDE writer (used for backing up the DPM databases) must be installed.
Limitations
• Hardware providers are not supported with DPM.
• If you start a backup while an incremental synchronization of the DPM replica is
still in progress, the backup gets corrupted, although Data Protector does not
report any errors. In case of synchronization with consistency check, Data Protector
automatically aborts the backup session.
