Snow Leopard Killed SuperDuper
 

I updated to Snow Leopard and got the latest SuperDuper (2.6.1) and it hasn't worked since then.

It no longer does backups. It just gives an unkillable window that says "The variable previousSettings is not defined."

No backups since Aug 27.

What should I do?

My guess is that's happening during a scheduled backup. Recreating any schedules should fix it.

Right, as sjk indicated (and as is mentioned in the release notes/revision history and the update notice, you need to delete and recreate your schedules.

Fresh install issues

I can see the sparseimage being created, but it fails to mount and then disappears.

The backup is being created on a network drive

That would certainly imply the network drive is failing, disconnecting or -- for some reason -- not retaining the file that was created.

Any suggestions? Everything was running fine before upgrading to Snow Leopard and the latest SuperDuper

Well, you've changed two things, one more serious than the other (Snow Leopard is a far greater change than SuperDuper! 2.6.1). Perhaps there's a problem between it and your NAS?

The error you're getting is coming from the system - we've asked it to create the image, and it fails with that error -- which certainly supports the "problems with Snow Leopard and your NAS" theory.

I think I've figured out the problem. The server is still running OSX 10.4, so I tried changing the backup file type from a .sparseimagebundle to a .sparseimage

Seems to be working fine now!

same error - regular Leopard
 

I found this forum and thread via google, after getting the same error this morning. But... I am not running Snow Leopard. I just updated to the 2.6.1 yesterday and the schedule ran last night for the first time.
I'll try the previous suggestion above that perhaps the schedules have to be recreated. Current system is 10.5.6.

Thanks for posting. Sounds like we found a bug.

It's quite possible that sparse bundles require advanced features of AFP that Panther and some NAS devices don't support.

To clarify as much as I can: this is a known issue, which is why its mentioned in both the update notice and the release notes/revision history.
