Hi,

I've been using rdiff-backup to backup several hundred gigs of data
for around a year now. It seems to work well so far. However...

One problem with backups of stuff that is rapidly in flux (eg. email)
is getting the stuff to be backed up to stay still while it is backed
up. :-) Otherwise rdiff-backup may fail, or at best will not make a
perfect backup.

I've been using LVM's snapshot facility for this, but it is not
perfect, since it seems to have problems with larger volumes with
rapidly changing amounts of data.

What are other people doing about this?
