OSX: Time machine backup failed, error code 11.


I am running a time machine backup that suddenly kept giving "backup failed" error messages. The description was completely unhelpful and after having restarted and repair the disk solved nothing, I had to open the terminal n order to know what was going on.

sudo grep backupd /var/log/system.log

Ah finally an error code, a quick search on google gave this helpful page: http://www.bytebot.net/blog/archives/2008/08/13/fixing-time-machine-backup-failed-with-error-11

Turns out deleting /Time Machine Backups/Backups.backupdb/nameOfComputer/date.inProgress  was enough :S. Thanks apl.
