Can someone please help decide what is the "best" backup software?

• Restic (https://restic.net/)
• Borg backup (https://www.borgbackup.org/)
• Duplicati (https://www.duplicati.com/)
• Kopia (https://kopia.io/)
• Duplicay (https://duplicacy.com/)
• Duplicity (https://duplicity.us/)

Do yourself a favor and use zfs as your primary backup, even though it means you'll have to replace your filesystem, it's just that good.

Faster than any other backup software (because it knows what's changed from the last snapshot being the filesystem itself but external backup tools always have to scan the entire directories to know what's changed), battle tested reliability with added benefit like transparent compression.

A bit of explanation on how fast it can be than external tools. (I don't work for the said service in the article or promote it.)

Then you'll realize Borg is the one with least data corruption complaint on the internet which is good as your secondary backup.

Easily checked with, "[app name] data corruption" on Google.

And see who else lists vulnerability and corruption bugs upfront like Borg does and know the developers are forthcoming about these important issues.

The term "best" apparently means reliable for backup and also they don't start choking on large data sets taking huge amount of memories and roundtrip times.

They don't work against your favorite S3 compatible targets but there are services that can be targeted for those tools or just roll your own dedicated backup $5 Linux instance to avoid crying in the future.

With those 2, I don't care what other tools exist anymore.

I use ZFS + Sanoid + Syncoid locally and Borg + Borgmatic + BorgBase for offsite.

Seconding zfs

Bupstash (https://bupstash.io/) beats Borg and Kopia in my tests (see https://masysma.net/37/backup_tests_borg_bupstash_kopia.xhtml). It is a modern take very close to what Borg offers regarding the feature set but has a significantly better performance (in terms of resource use for running tasks, the backups were slightly larger than Borg's in my tests).

Personally I use borg with BorgTUI (https://github.com/dpbriggs/borgtui) to schedule backups and manage sources/repositories. I'm quite pleased with the simplicity of it compared to some of the other solutions.
