Hi All
I havbe my time machine setup over an Airport Extreme and until the recent software upgrade on October 2011 i have been getting the following message when Time Machine tries to access the external HDD to backup my mac:
The backup disk image “/Volumes/Data/xxxxx’s iMac.sparsebundle” could not be accessed (error -1).
can anyone help as i am concerned that my information is not being backed up daily
Many Thanks
iMac
Try running disk utility on your hard drive to repair it, also repair your permissions. If you are still having problems take a look at this link, http://support.apple.com/kb/HT3275
I have not found a long-term solution (fix), but in my case the volume where the Time Machine backup should occur usually is mounted on the desktop but not as a shared volume (incidated as a drive with the people holding hands superimposed over the drive icon). If I drag the drive to the trash (unmount it), the next time Time Machine is scheduled to run, it completes successfully.
Time Machine Backup Error-1 - what the??
