I am fighting with snapd since yesterday… Long story short: snap is broken, I am not able to start the caddy, the rocketchat-server or the mongo database and I have not a single manual backup. (I was so naive that I thought those are created automatically). If someone is interested, here is my desperate call for help regarding the snap installation: https://forum.snapcraft.io/t/snap-is-broken-cannot-perform-operation-mount-bind-snap-core-current-etc-alternatives/8253
Now I have only the files on the machine (and a full system backup of 4 weeks, but none of them with a working snap, it seems that the issue was there for a long time and only revealed when I did a system update).
My question: how can I rescue the data of Rocket.Chat and feed it into a fresh installation? As far as I understood everything is stored under
/var/snap, but where is the actual mongo database file, or how can I make a valid backup archive, which is recognised by Rocket.Chat?
