Anyway I took this opportunity to combine two of my previous jobs into one. I save the same set of data via other methods as well so I knew what to select for backup. This time I selected ~/.config/tarsnap/tarsnap.db as well (maybe I will add cache files “directory” and “cache” as well later or in some other backup). (I will also consider pruning old archives - in a way all the files ever backed are preserved i.e. out of e.g. 200 archives if I can have last 7 + min number of archives post that that has all my data ever backed up)
