Auto-Remove not working

[michael da cova]

I have a 500gb disk with 1.9g disk space left
I have set auto-remove to, keep for 1 year, if free space is less than 2gb
smart remove, 2d,7d,4w,24m and don't remove named snapshots
I have snap shoots 1 of each for dec-2010,jan-june-2011 last week and 3 this week, when I run the backup I get insufficient space

os is ubuntu 11.04 64bit

You can get the size used by all snapshots by getting the size ("nautilus" or just "du -sh <path>" command) of the folder:
   <SNAPSHOTS PATH>/backintime

I see that you backup virtualbox drives (*.vdi). This file can be real big and change every time you start the virtual machine.
You should check this files sizes.

The problem is that BIT remove old snapshots only after it takes a new one (because it doesn't know how disk space it will use).
If you take big snapshots you should change the rule to "if free space is less than 50gb" (or more).

I do a backup of my laptop every day before I start using Virtualbox,
and must say BIT has saved me on a number of times

  I removed one of the snaps and all is working again.

Keep up the good work, is there a user forum

No, at least not for now.

Even it works now it can stop working next time.
You should evaluate the size of a snapshots and configure "if free space is less than XXX gb" where XXX is the size of a full snapshot + 2-3 GB.
