Automate Backup of Factorio Saves (self.factorio)

I found this Python script a few years ago, it is simple enough that a non-programmer could understand 90% of it. I just remembered it had been running as a scheduled task all this time when I thought I had lost some saves.

Thought I'd post it here in case anyone can use it. Minor things are hard coded but they are few and easy to edit.

Neat. Mine are saved on steam cloud and in my system wide backups

Ah yeah, I did that for a while until my save files started going over 200MiB, and I timestamp my base 4-5x per session, so I'm usually generating about 1-2GiB worth of save data per session (depending on the base). Steam cloud was no longer an option, so I had to fallback to some sort of manual solution.

Maybe Steam cloud is improved now? In that case I could re-enable it and have a double backup :)

My Factorio save list is... Unwieldy

[–] stembolts 3 points 5 months ago* (last edited 5 months ago) (1 children)

Same. Dozens, maybe hundreds of files most of them 250-300MiB.

The nice thing about automation is I have no idea, it just works!*

(As long as your save files are in one parent directory.. and not in a place with other "zip" files)

Snapshotting really helps too! (file system level)

It's really cool! Though I just do a backup both to my external HDD with rsync and Steam Cloud
