Incremental Backups Not Working - DPM 2012 R2

Question

Hi
Having a strange issue where incremental backups in some situations are not working, however the daily full backup is succeeding.
This doesn't seem to be a SQL instance issue, in that within the same protection group, on the same sql instance, the incremental backups are working on other databases.
All of the databases are set to full recovery model, and I'm not seeing any failed jobs (although when I check the jobs, the only scheduled job is the full backup, none for the incremental backups are listed (which isn't the case for the databases that are
incrementally backing up).
What am I doing wrong?

Answer 1

Hi,
I recommend the following to start troubleshooting for one of the problem databases that incremental backups seem to not take place on. Carry out the below.
From DPM console select the protection tab navigate to one of the problem SQL DBs.
Select Recovery Point from the top ribbon.
Within the Create recovery point Window if you identify that the second radio button (figure 1 is greyed out) DPM thinks the SQL DB in question is in a recovery model of simple.
Ensure the SQLDBs in question are set to a recovery model of Full or Bulk-logged.
Select the protection tab navigate to Protection Group with the problem SQLDB select Modify Protection Group. From the select group member’s page select the Server in question and then select Refresh button step through the rest of the wizard and select
update group at the end.
Note if you do not see the refresh button just walk thought the rest of the modify protection group wizard and select update group at the end.
