Re: What all do I need to migrate tarsnap-gui setup to new MacBook?
Thanks for the info!
On minor warning: in point 2, you added a name for the new laptop.
Unfortunately version 1.02 of the gui is misleading: that field doesn't do
anything. The "machine name" is only used when creating a new key; after you
have a keyfile, all archives made with that keyfile come under that name.
(That field has been removed in git master, and will only be present in the
setup wizard if somebody is creating a new key.)

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)
