I have a 3TB time capsule to which 8 different computers backup. Every week I archive to an external disk and take off site. The total size of the backups is 1.31 TB and my external disks are 2 TB. Up until recently the archiving has worked perfectly but now the archiving stops at 1.05 TB and a Achieve_temp file is created. Does anyone have any suggestions as to what the problem is?
