Yesterday I followed Erik J. Barzeski’s instructions to configure Time Machine to backup to a sparse bundle disk image on my Drobo. I wasted a lot of time trying to figure out how to tell Time Machine to use the disk image and not the whole disk; eventually I discovered that if you just select the disk, Time Machine finds the properly named disk image and automatically uses that. So, if you happen to think like me, I hope this note has saved you a few minutes of confusion.
Other things I’ve learned:
- Changing the volume name of the backup disk during a backup will cause the backup to fail and start over again. Not a big deal.
- If you want your backup disk to have a nice looking Time Machine icon, you can find it in the file GenericTimeMachineDiskIcon.icns in the folder /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources.
