All but about a couple of backups a week are failing between Time Machine and my Macbook Air. The error message from Time Machine is
“Time Machine couldn’t complete the backup to “WDMyCloudMirror_AFP_TimeMachineBackup”. The backup disk image “/Volumes/TimeMachineBackup/[name]’s MacBook Air.sparsebundle” is already in use.”
- My Cloud Mirror (1st gen) with ver 2.11.153
- 2013 MacBook Air running macOS Sierra 10.12.1, with 8GB of RAM
Any advice is appreciated.
