I am running a Drobo FS with 4 x 2TB drives set to dual disk redundancy with a 1TB partition for Time Machine on Mac OS X 10.6.8.
Everything was working fine for a few months but recently I have had much trouble with Time Machine.
First TM said the back up disk ran out of space unexpectedly and it would try and make space by removing expired backups next back up. But next back up it tried to back up my entire computer (240GB) when less than 10GB of data had changed.
Then it got into this situation where TM said it was backing up 120GB of 120GB and both these figures remained in sync and kept going up? This happened a number of times so I had to stop the back ups.
Today TM has been stuck on backing up 1.24 GB of 9.26 GB for hours with out these figures changing, so I again had to stop it, which took hours more to stop and clean up!
Looking at the Time Machine partition I notice it has created a .sparsebundle and a .tmp.sparsebundle is this correct?
I am wondering if I should delete both of these files and start again with Time Machine?
Any advice greatly appreciated?
