Problems making a backup imagine

[ajcowell]

I'm backing up my powerbook to a firewire drive. Back works fine. Problem comes when trying to unmount the drive to create an image. The end of the log is shown below:

|11:04:22 AM|Info| Scanned 111794 items occupying 8.64 GB (21149 directories, 87737 files, 2908 symlinks)

It seems it's looking to see if there are any open files but can find none. Help!

I should have mentioned that this sometimes works fine, but almost every other time it fails. Sometimes I just restart the application and retry, other times I reboot and retry. This morning, both of those approaches have failed.

OK -- let's see what we can figure out here!

I don't have much information about your system: typically, unmount problems are due to running things like Norton AntiVirus or Utilities while doing the backup. Recent versions cause the image to be scanned, and since NAV opens files to scan them, you can end up with an unmount failure. Is that possible in this situation?

[ajcowell]

It certainly is possible. I do have NAV on there. Will make sure to turn it off first. I was able to use disk utility to create an image that worked perfectly but it would be nice for it to work without having to use another util.

Will let ya know how it works out!

OK, I'll look forward to your response.

Yep, looks like that was the problem. Maybe thanks for the help!
