Okay, this has taken me many hours and I still can't fix it. Here's my problem.
I have been using Time Machine to back up three of my computers to a DNS-323 network attached storage drive. For months, I've been doing this with a Netgear router and using the sparsebundle images that are suggested throughout this discussion area.
However, on the same day last week, I got a new MacBook Pro (fully updated to latest software) and an Airport Extreme Base Station. The backups for the three original computers still work fine with the AEBS but I cannot, for the life of me, get the new MacBook Pro backup to work through Time Machine. The backup starts preparing but I guess the dreaded "Backup disc image could not be created" message after about a minute of chugging.
I have troubleshooted the following:
1. took out all spaces and punctuation out of the computer name in the 'Sharing' preference tab and the sparsebundle image name (although my other backups all have spaces and apostrophe's in their names - ignorance is bliss I guess)
2. made sure ethernet address is same in MBP and sparsebundle image name
3. made sure I've got proper r/w access to the sparsebundle image after I've moved it over to my NAS
4. I got rid of the sparsebundle image entirely off of the NAS and received the same error message.
I know this error msg pops up if there's a disconnect between the computer name and the sparesimage name but my computer name is 'MacBookPro' and my sparsebundle image name is 'MacBookProxxxxxxxxxx.sparsebundle" which I created with Disk Utility (as I did with my other three images (xxxxxxxxxx is my ethernet address).
I'm fresh out of ideas and would greatly appreciate any help anyone could provide.
Thanks in advance
