Q: The backup disk image “/Volumes/Data/iMac.sparsebundle” could not be accessed (error (null))

The above happened, but I also deleted the sparse bundle manually to make room for more backups (they weren't self-deleting to make room). I was following directions from another site, but I think I did the wrong thing. Please help...

MacBook Pro (13-inch Mid 2009), iOS 10.0.2

    You should never, ever, delete Time Machine backups manually. If you get the message that there is not enough space, you can check the checkbox in Time Machine Options that says, "just do it (delete the oldest backups to make room) and don't ask me again"

     

    A sparse bundle is a drive inside a folder, and when it needs to be reduced in size to make room, only Time Machine knows what can go, what must stay, and how to reduce the size.  You should not store other files on the same Volume as Time Machine files. If you must store them on the same drive, partition the drive so that Time Machine knows EXACTLY how much space remains on its Volume.

     

    I expect you have fatally damaged your Backup set and should start completely over. Remember that your FIRST Backup of a new set will be an all afternoon to overnight affair. It will not slow you down very much, but it will not finish quickly.
