Home Forums Discussions Problems SBS2011: delete backups to free space?

Can somebody (probably Sandeep) tell me how to free up backup space taken by client computers in SBS2011. The volume that has AC is on is about 400GB of which 300GB is taken up by client backups! (and is now full) I have removed most clients from backup list and reconfigured the remaining few clients to only backup data directories.

But the space used does not re-adjust. Does this happen at the next scheduled backup?

Also, how do I know the server is not being backup'd twice (as a client and under the server backup application).

Thank you in advance for your help.
