Duplicity VS others

http://duplicity.nongnu.org/ at least can use PGP public keys. I've used it for a long time and not seen any particular reason to change.

There are backup tools with built-in encryption like borg backup or duplicity, these should be fine. If you already have a backup process and it's missing encryption then you should be able to use e.g. age or gpg.

For my family photos (critical, irreplaceable, on plex), I use duplicity which can make use of Amazon Glacier and Deep Archive for really cheap storage (0.00099 /gb /month no joke) with incremental versioning and client side encryption. Long restore time, but perfect for disaster recovery on data that doesn't change much. Want to set up the same for music (which rarely but sometimes changes, e.g. Correcting tags).

And google docs / apple cloud etc. aren't proper backups. They can cancel your account, be inaccessible, or hacked even. There's software like duplicity that can upload encrypted backups to multiple services, which are handy. But in any case, if you're doing cloud backups, do do redundant local backups too. My setup is I've a USB stick tacked onto a Raspberry Pi computer, and use something called borg to do daily backups over SSH.

I have had good success using [Duplicity](http://duplicity.nongnu.org/) via [Duply](https://www.duply.net/) for a few years now. The main point for me is that duplicity directly backs up to many cloud-storage endpoints. I'm using google drive specifically, but it supports a ton of options.

Also see Restic's list of Linux backup software. https://github.com/restic/others

There is also https://github.com/restic/others which has some keywords (e.g. is it encrypted, does it do compression) for most FOSS backup solutions. It can be outdated or incomplete for some entries, though.

https://github.com/restic/others is a nice collection of free software links too - you can click through those and see if any are Windows supporting. But I'd personally just go with restic.

Backblaze is an awful piece of software when you look at it from “a backup software” point of view. It’s made pretty, simple, native (or is it Electron now?) - yes. But then it stops there. On top of that if you read there ifs, buts, and gotchas you’d want to stay far away from them.

They’ve downright absurd data deletion/retention and versioning rules.

Besides I do not trust any service that promises to give anything “unlimited” for a fixed cost.

As I usually mention in comments on this topic - I’d strongly urge people to use and support backup tools like borgbackup.org (Vorta is an excellent Borg GUI), restic.net (a GUI is glaringly missing), kopia.io (up and coming; promising; comes with a GUI), for smaller datasets there’s very good but more expansive Tarsnap (not FOSS).

And then there are others - https://github.com/restic/others#list-of-backup-software
