Hi guys. I have a very small installation of OS X, my total install up until a few months ago was only 40GB or thereabouts. I recently switched my VM from bootcamp w/fusion to a pure VM with parallels, in part, so that I could start to use Time Machine to backup my Windows installation also. I am using the Parallels option 'optimize for TM' with snapshots. Around the time I did this, I increased the quota size on my Synology Diskstation so that I would have more room for TM backups. My original quota was for 100GB, which worked for years without ever complaining the backup disk was full (I think I had used perhaps 60GB of the 100GB that was available). I increased this to 200GB so that I would not run out of space anytime soon with the 25GB or so that the Windows VM was going to take. However, I am now getting "disk full" messages from TM almost every time I backup and it has removed most of my older backups (my oldest backup is now only six weeks old)... what's particularly confusing is that right in the TM preferences I can see that my backup disk has over 100GB of free space. Is there any way to fix this short of destroying my old TM backup and starting over? Thanks.
