I like pikabackup it’s based on borg

There is no such thing as the objectively best solution. Each tool has advantages and disadvantages. And every user has different preferences and requirements.

Personally, I am using Borg for years. And I have had to restore data several times, which has worked every time.

In addition to Borg, you can also look at Borgmatic. This wrapper extends the functionality and makes some things easier.

And if you want to use a graphical user interface, you can have a look at Vorta or Pika.

I don't have backups. :/

And I will regret it some day.

I use github for code so that's backed up though.
