Pictrs is a mix of both cache and long-lived images on anything you post, your profile image, etc. So you may want to back it up… Apparently there may also be some sort of internal database pictrs uses as well, but I haven’t looked into that…
I would suggest taking postgres dumps and backing those up rather than trying to back up the data directory, as according to the pg docs when taking a disk-level backup “[t]he database server must be shut down in order to get a usable backup.”
