I'm not an rdiff-backup developer mind just a user.
I think you might find a few bits of software that crash if they run out
of hard drive space.
There are other alert programs that alarm when drive space is getting
low.
True, except all of this works from cron, when i have a 100G filesystem to
back up every day, it's very difficult to calculate at what threshhold it
should send a warning.
- The real problem is that you can't add space to the storage, and so you
loose all your backups because you ran out of space: this (in my humble
oppinion) kind of beats the purpose.
Sure it would be nice if rdiff-backup could recover and save one when
this happens and it
does happen. There was some discussion on list some time back about
being able to specify
temp space so that rdiff-backup could perform at least a roll back.
Imho there is no need for temp space for cleanup (removing snapshots), but
that's just my first impression, didn't dive that deep in the code
Another option is to have rdiff-backup look for a certain amount of free
space (configurable) and fail if its not available
Again, very difficult to know how much space is needed for a new incremental
step for the filesystem beforehand.

Yes one could certainly put this in the wrapper script that is calling
rdiff-backup.
Not sure how easily rdiff-backup could do this in a cross
platform/enviroment way.
Cheers

It is an interesting topic of discussion as i think many users are affected by
this issue, and it shouldn't be that difficunt to fix, since there shouldn't
be any need for free space for cleanup.
Thanks for the comments.
John
