Hello

For my Server 2012 Essentials, I backup the server manually ("Backup once") - since today I cannot backup any more as there is insufficient space on the external USB disk.

How can I free up space? If I ran "Backup Cleanup", nothing happens, the disk space on the HDD remains the same.

I'm assuming you're backing up to the said external USB drive?

 

If so, I don't think there is a way to clean that.

 

What is the capacity of the disks that you are a backing up, and the of the backup drive?

Yes, I'm backing up to that external USB drive.

I even have 2 external drives, which I use alternately to backup to, I rotate them after each backup.

 

As I don't need automated backups, I followed your instructions in another post here and changed from regular backups to one time backups (backup once). But now the external USB drive is full, and - as you write - there unfortunately is no way to cleanup old backups.

 

I switched back to regular backups yesterday.

 

The capacity is: 120 GB OS disk, and 2 x 1 TB drives (but only 600 GB used at this moment, on all drives). The USB drive has 1.5 TB.

Aside from formatting, I'm not sure there is a way to "fix" them.

 

I think that if you're not setting up a schedule, each backup takes up additional space, rather than being incremental. And I think that's what is happening here.

 

Though, I'm not sure, and there isn't a good way to check.

Thank you! Yes, I think the only way is formatting.

And - it seemed to me that the updates weren't really incremental. They took more and more space.
I reverted back to scheduled backup. I did one full backup yesterday, and 2 incremental, which only took a few minutes. With these one time backups, each backup took 1 hour ore more.

If you're doing manual backups, they may not be incremental. I'm not sure, to be honest.

 

And as for the scheduled backups, I'm using a 2TB drive, which is backing up a 120GB SSD, and a 500GB partition. It's not used more than maybe 300GBs.

Yes, that's what I think, too.
I'm using scheduled backups again.

Thank you for your suggestions - as always!
