Depending on what's being backed up, I use either duplicity or rclone for online storage. Both of them will back up to S3-compatible object storage.

At work, we have a Synology RS3621RPxs on which MinIO is running in a Docker container to provide local object storage. It holds archived VM data stored with rclone, among other things.

Thanks for the suggestion.

I bought a USB drive and formatted it to ext4 and used rsync to back up
the Pi 5.

DonrCOt forget the tips on how to keep a rolling set of timestamped backups, without needing space for extra copies of files which havenrCOt changed.

rsnapshot does that for you, using rsync and hard links.

Sure, these convenient wrappers around rsync handle some common cases
with less work. But they still donrCOt offer the full power and
generality of rsync itself.

Also, rsnapshot refers to this article <http://www.mikerubel.org/computers/rsync_snapshots/>, which has been
obsoleted by the addition of --link-dest to rsync. Does rsnapshot make
use of that to simplify things?

That page is 20 years old!

The rsnapshot utilitiy will take care of rotating your snapshots (keeping
N daily/weekly/monthly etc) which pure rsync won't do.

It looks like it can optionally use --link-dest with a config option:

link_dest 1

If your version of rsync supports --link-dest (2.5.7 or newer), you can
enable this to let rsync handle some things that GNU cp or the built-in
subroutines would otherwise do. Enabling this makes rsnapshot take a
slightly more complicated code branch, but it's the best way to support
special files on non-Linux systems.
