What about retention? How long are the backups kept?
Currently forever. Sometime down the road we might start pruning them.
We are currently using about 2TB of a 25TB volume and it's growing
I'll add a note.
On my own systems, I run rdiff-backup with
`--exclude-if-present .NOBACKUP`. This makes it skip any directories
containing that file, and is useful for subdirs with a lot of churn.
For example, /etc/selinux/targeted -- but perhaps most useful for
people to put in home directories where they may be dropping large
temporary files that are actually okay to not be backed up.
Good idea, we could add this if there's call for it.
Also, you probably already know this, but rdiff-backup does not have
any special handling for moved files -- they are treated as deleted
and created anew. This can mean that simply renaming something a lot
can use up a lot of space (unless of course the underlying filesystem
is deduplicated, of course).
The netapp volume we are using is in fact deduplicated, also we aren't
backing up /var/log/ or the like on most machines. (we are backing up
logs from log02 which gets a copy of them, but it's setup to use
