Hi,

I need to move protected server to another group

When I stop protection and then add to new protection group, DPM transfer inactive protection.

Old protection group reduce allocated disk space, but in manage->disks unallocated space does not grow.

How to free used space in disks ?

Hi !

1) Try go to DPM console -> Management -> Disks -> Action "Rescan"

if you have not result that go to step 2

2) You can try stop dynamic DPM service and put disk to offline. And after that put dynamic DPM disk to online and start DPM services.

Have a nice day !!!

Hi,

It's not works, because DPM does not delete old partition although backup data are in new partition.

I found other way to free space:

Before moving I look to partition name

After move I delete it

Unfortunately old recovery points not accessible

I think DPM allocates new space, but old backups keeps in old partition until they will expire.

Thanks,

I see that does not passible to move backups.

My problem still not resolved. I need to save/export backups and create new backup job to new HDD

MigrateDatasourceDataFromDPM does not suitable because it does not clear out old disk until backups expires.
