Recently Time Machine has stopped backing up to my Time Capsule on both my MacBook Air and MacBook Pro. It spends a few hours "Preparing backup" and then just gives up.
I've had a look in Console and when it says it is "Preparing backup"
com.apple.backupd is running an
initial consistency scan for '/' and then when it stops I get the following messages in the Console:
Error writing event cache at /Volumes/Time Machine Backups/Backups.backupdb/... : Error Domain=NSPOSIXErrorDomain Code=20 "Not a directory" Error writing to backup log. NSFileHandleOperationException:***
The latest backup on my MBA is 23 July and on my MBP is 24 July so I think that coincides with me updating OS X but I can't be sure. These are the things I have tried so far (I've turned Time Machine off on my MBP so I can focus on getting the Air working first)
- Turning time machine off and back on again
- Reselecting the back up disk
- Hard resetting the time capsule
- Factory resetting the time capsule
- Booting into Safe Mode on my MBA and then restarting into normal mode
- "First aid" (Disk Utility) on my MBA
- Renaming the Time Capsule to a short name
The only thing I haven't done is erase the contents of the Time Capsule for two reasons. 1) I don't have a hard drive with enough capacity remaining to archive the data to. 2) When I enter Time Machine all of the backups are there and available for me to restore so I don't want to loose all that.
Please let me know if you have any ideas. The TC has over 300 GB of space remaining.
