Another sparse image bundle failure

What does this mean?

I can’t tell you how little faith I have in Time Capsule.  My week is filled with troubleshooting this failed implementation from Apple for a wifi backup system.  It’s even number 6 on my least favorite products list for exactly the reason you’ve come across here.  I even put on the front page of my web site from time to time “don’t trust time capsule”.  As a router, it’s great but as a backup system, the method that apple chose to encapsulate your data is called a sparse image bundle.   And that is the cause of the problem.  This method is very fragile and prone to failure.  While there are ways to resolve it, I’ve found the easiest thing to do is simply reformat the drive and start the backup all over again.  However, I strongly encourage you to take the same opportunity to go out and buy a good old USB drive for backup.
