Duplicity

I'm a huge fan of this backup tool. Used for around 5 years for sure.
But I suggest using duply.net (front-end part for easier managing and configuration)
https://wiki.archlinux.org/index.php/Duply which can be configured just in 2-3 minutes and you're ready for doing backups where you want.

Cons:

• in repos super old versions with tons of bugs
• even new versions full of bugs
• different alternative storages require extra python tools installed (and very frequently does not work)
• no modern features which offer restik or borg.
• not so fast as restic or borg
• hard to say, there is a lot what can I say about the program by using it for really long.

Pros:

• duply.net (front-end fork) super easy to configure and use, any newbie can configure for himself backups and add it to cron via few clicks and editing really human-friendly config file with examples and short documentation.
• pretty fine works for years. If you properly configure it once and do not update, it will work for years without issues.
