Backup of VM frequent  full backup.

Hello,

DPM 2012 R2 UR6, protecting many VM's. Some of them, have VHD's of 400 - 1500 GB. These VMs very often are backuped as full backup. 3 times a week backup downloads only changes, about 10GB of data. Other 4 times a week DPM downloads all VM's data on backup job, 400 - 1500GB of transferred data. Why ?

On these VM's nothing special is happening. they are just RDS or File server.

Are all of these backups full backups? I suspect some are express full and others full?

I am suspecting following

- 3 times a week, incremental backup (express full) is happening which is why only changes are backed up

- Other times a full backup is happening.

Can you re-validate PG settings in DPM?

There is no long term retention.

Only short term retention with HDD disks.
