May I ask why you decided to switch from rsnapshot to rdiff-backup, and
then to borg?
The main issue I hit with rdiff-backup was if I wanted to move files
or directories containing large files around on my storage: that
resulted in the new locations being considered "new", and the next
backup increment being comparatively large.
I use rdiff to do the backups on the "server" (its job is serving video
content to the TV box over NFS) and ran into that problem, so what I did was
write a series of scripts that relinked identical files. It's not perfect,
I suspect there are still bugs. It tries to be efficient (by not comparing
files that can't possibly be the same because they have different sizes, or
are already linked), but it gets the job done. Eventually. Running it
takes about as long as running the backup in the first place. But hey,
we're talking about 1 GiB of filespace which might change by 10-20 MiB
between backups, so not a big deal.
