When protecting a SharePoint farm, DPM takes the disk backup for all the databases that are online at that time. When DPM retries backup for failed databases, two different recovery points are created for the farm.
If long-term backup is configured for a SharePoint farm, DPM needs to find databases across multiple recovery points and ensure that the complete set of databases in the farm are backed up on tape. To do this, DPM does the following:
Checks the list of databases present in the latest topology of the SharePoint farm. The latest topology is stored in DPM.
Checks the latest recovery point on the disk and copies the databases on the disk to the tape.
Checks the previous recovery point for all the databases that were missing in the latest recovery point.
Similarly, DPM traverses older recovery points one-by-one unless the recovery points of all the databases are found.
If there is a database for which a recovery point was not created since the last successful scheduled tape backup, then that database’s recovery point on the tape fails.
|Long-term protection for a SharePoint farm on tape is available only on the primary DPM server.|
