What do you use to back up local files from Linux to external hard drive?
I have been using rsnapshot, but maybe there are better solutions out there?
Does anyone have an experience with btrfs and snapshots? Do you trust it?

@mirekdlugosz I am a big fan of restic at the moment. Encrypted backup repo by default. Validity checks. Easy to learn cli for most basic tasks.
I just use a few one liners for backup, consistency checking, mounting and restore.
@mirekdlugosz What's your use case regarding btrfs snapshots?
I would recommend other methods like rsnapshot, restic, borg, etc. rather than filesystem snapshots in most cases.
@blasfisq
I donโt have one. The question is what pros and cons of such thing would be.
I imagine doing rsync from laptop to external drive, and then doing btrfs snapshots on external to go back in time (like recovering old version of file etc).
@mirekdlugosz a pro argument would be space efficient and fast local filesystem snapshotting to use them to recover e.g. from mistakes like accidently deleting files, corruption, broken system upgrades and so on. Those snapshots are not backups.
Visone already mentioned a solution to combine btrfs snapshots - on the same drive - with other tools to replicate copies of the snapshots to external storage locations. @visone
@mirekdlugosz 2/2 con argument would be that you need more tools, more manual consistency checking, separate tooling for encryption and so on.

For the mentioned use case I'd recommend restic in combination with the 3-2-1-1-0 strategy if possible: https://www.techtarget.com/searchdatabackup/tip/How-the-3-2-1-1-0-backup-rule-reflects-modern-needs
@mirekdlugosz I don't do external drive backups. My main reason for it is: if I get infected with ransomware (doubt, but who knows) then the external drive will also be fcked.
I use Borgbackup via https://www.borgbase.com/
They have a thing setup so that even if you have the api key to backup to borgbase, you can't mass delete all the backups. Only if you login can you do that.
They make an easy to use backup client as well: https://vorta.borgbase.com/
