When I try to make a back-up using time machine, the back-up gets to about ~500 MB and than halts. The following error is given:
An error occurred while copying files. The problem may be temporary. If the problem persists, use Disk Utility to repair your backup disk.
I've already repaired the disk several times, so I believe that is not the problem. The errors given by console for "backupd" are -
Copy stage failed with error:11
Backup failed with error 11: 11
Another error message also popped up several times, from the process "TMHelperAgent" -
Month 13 is out of bounds
I'm using a 2016 MacBook Pro, running MacOS High Sierra (version 10.13.2). The hard disk I'm backing up to is a Samsung 1TB SSD, partitioned into two volumes (one for data, one for the backup).
