I can only stand in line with the rest, there is having issues with the latest firmware and TimeMachine.
All to late I did found a workaround for corrupt backups (http://bit.ly/GIuk7e
), but I ditched my backup and started from scratch - bad idea.
I think I have tried everything. Deletet the TimeMachine sparsbunde file, re-enabled the TimeMaschine service, created a new backup, that fails because I only have 140 GB of the 500 GB allocated to do an initial backup on 250 GB.
What I can't figure out if this is a Mac problem (is there a setting I have missed, that keeps trying to do more backup than the 250 GB), or is it the buggy firmware of QNAP.
What ever it is, it is not a reliable situation, given in mind that most of us by a QNAP do do some backup.
I am somewhat disappointed right now
EDIT: Just an update, since I spend all night trying to figurering this out.
If you are running Lion (OSX 10.7.x) you can't downgrade due to changes in the AFP. Latest firmware that supports Lion is 3.5.x
This seems to be consisten with what other is writing, people running prior versions like Snow Leopard (<OSX 10.6.x) doesn't have these problems.
What stills annoys me is, that even if I delete the sparsbunde and create a new fresh version, the TimeMachine still insists there is allready used like 400 GB of my TimeMachine space, and I have not yet figured out what is taking up the space...
