Mount Sparseimage - what is happening?

[raf]

OS: 10.5.2
SD: 2.5 v84

I too have had nothing but grief with network images and SuperDuper. It seems to fail (not mounting the image) most of the time. And to top it off, the Growl notification system is not reliable in telling you when it fails. In the end, I just gave up trying to debug the problems and attached a firewire disk as needed to each computer manually. Not really an ideal solution.

Now I have a TimeCapsule with a 500 GB internal disk and an external USB disk. I want to use TC as a NAS so I tried to backup to a sparse image on the external disk. It got about 1/3 of the way through after 4 hours (30 GB done) and I mistakenly put the MacbookPro to sleep. When SD woke up it said that it failed since it couldn't find the image. Understandable, although the finder seemed to remount the time capsule just fine.

In any case I tried to continue the backup manually: it tried to mount the image and failed. When I tried to mount it in the Finder it told me that the image was un-repairable. Apparently, putting SD to sleep in the middle of the clone trashed the image. I deleted the sparse image and set SD to try again tonight, but the fact that it trashed the image when stopped doesn't give me confidence that i will always have a recent bootable image. One interrupted backup and it could go through days or weeks of failing to mount the corrupted image without me knowing about it. And Murphy's Law being what it is ...

So now I really don't know what to do. Ready to give up on this whole idea. Anyone have any ideas on how to get this to work reliably and without constant attention from me?

Thanks,
Martin
