Got a strange problem here...
On my Macbook Pro (6,1), i7 2,8Ghz, 8Gb ram, 500Gb HD i have Time Machine running to a network disk.
OS X: 10.6.7
All works well for a while, but suddenly i get a warning from TM, saying that it needs 178Gb of backup space to do a backup, and it doesn't have that much available.
The funny thing is, my Macbook HD is only using 160Gb AND i have about 120Gb in the Excluded list.
Only way i have found to fix this, is disabling TM, cleaning the backup drive (removing all files), rebooting my macbook, enabling TM and do a complete new backup.
If i follow that procedure, it says (during backup): "Backing up ... of 37.38Gb", which is WAY more realistic (and actually about the size i would expect of a full new backup).
So my question is: What is the cause of this problem, and how can i fix it without doing a full clean backup?
I had to do this procedure three times in the last 2 months, btw
*i searched the forum, but couldn't really find a similar problem, sorry if i missed it*
