There's different kinds of backups. For this you don't need off-site storage.

For this I set up zfs auto snapshotting which means when I delete stuff it isn't really deleted because a snapshot is still pointing at it until it rolls off the time window.

Both zfs and btrfs can do this but you do need to change the filesystem to use these which can be a lot of work.

Restic or Borg. For restic I use the great Backrest web GUI.

I mounted an USB drive to one of my OpenWRT access points and backup on that one.

Rclone or fuse can mount/access Google Drive and can be used as back end for your backup choice.

Simplest backup ever: restic/Borg on a folder on the same PC. Not very recommendable, but indeed a good starting point.

Zfs/brtfs seems a complex solution for a simple problem. True is that once you start eating you get hungrier so maybe worthwhile.

You can combine it with a FUSE mount of the Google Drive, I’m not sure if that works but I don’t see why it wouldn’t.

Restic, it has native S3 compatibility and when you combine with something like B2 it makes amazing offsite storage so you can enjoy the tried and true 3-2-1 backup strategy.

Also fedora magazine did a few posts on setting it up with systemd that makes it SUPER EASY to get going if you need a guide.

I have an ansible role that configures it on everyone’s laptops so that they have local, NAS, and remote, B2, backup locations.

Works like a charm for the past 8+ years.

rclone & restic work okay together to create backups in a Google drive mount. There are "issues" with backing up to Google drive since it doesn't guarantee file names are unique which is... a choice... but it should be reliable enough.

I use duplicacy, it's free as cli and pretty cheap if you want to manage the backup via gui. Restore by gui is always free and I would recommend it because it's way easier to navigate the backups if you want to restore single files or folders.

simplest tool to backup to Google drive

Without the need for versioning, I think rclone fits the description. For backup into USB drive / remote SSH server I would recommend rsync.

For those kind of issues I'd recommend snapshots instead of backups

I just uh, wrote a bash script that does it.

It dumps databases as needed, and then makes a single tarball of each service. Or a couple depending on what needs doing to ensure a full backup of the data.

Once all the services are backed up, I just push all the data to a S3 bucket, but you could use rclone or whatever instead.

It's not some fancy cool toy kids these days love like any of the dozens of other backup options, but I'm a fan of simple and well, a couple of tarballs in a S3 bucket is about as simple as it gets since restoring doesn't require any tools or configuration or anything: just snag the tarballs you need, unarchive them, done.

I also use a couple of tools for monitoring the progress and a separate script that can do a full restore to make sure shit works, but that's mostly just doing what you did to make and upload the tarballs backwards.

I had use Duplicati and Kopia. Duplicati works kinda well, the problem is the installation is such a pain in the ass, actually it never work as intended, that's why I switched to Kopia, the installation is a lot easier, have GUI and and system tray icon, have better documentation, the Google drive backups with GUI requires a liltle configuration of rClone , nothing crazy
