backups

backups are done with vykar to borgbase

always remember to docker compose stop before doing any of this!

creating

• if on a new borgbase repo, run vykar init first
• to back up, run sudo vykar backup (sudo required as we are accessing /var/lib/docker/volumes/)
• to back up automatically, run sudo EDITOR=micro crontab -e and add the following:

  TZ=UTC
  0 6 * * * /home/admin/thingy/scripts/volume-backup.sh
  

restoring

the restore process is kind of fucked up but doable

• restore on new system
  • run vykar list to find a snapshot to use
  • sudo rm -rf /var/lib/docker/volumes/
  • then sudo vykar restore abcd1234 /var/lib/docker/volumes/
  • figure out the UID:GID for all containers and sudo chown -R UID:GID /var/lib/docker/volumes/.../_data/ their respective volumes
• restore on same system
  • run vykar list to find a snapshot to use
  • then sudo vykar restore abcd1234 /var/lib/docker/volumes/

todo

• further secure the server (ratelimiting, hardening...)
• figure out best way to store .env, other credentials, and various secrets
• more services
  • gitea (need to change host ssh port)
  • vaultwarden
• tie all services together with an sso
• use postgres for everything

misc

useful commands

• docker exec <service> env
