Backing up

Preparation

  1. Copy the backup and backup-rotate scripts to /usr/local/bin
  2. Create a /backup folder (which might be symlink to a mounted file system`

Define cron jobs

Add cron jobs (in /etc/cron.d/backup) to run rotation first, then for each folder which is to be saved:

0 0 * * * root /usr/local/bin/backup-rotate
10 0 * * * root /usr/local/bin/backup /etc etc
10 0 * * * root /usr/local/bin/backup /var/lib/docker docker --exclude overlay2
10 0 * * * root /usr/local/bin/backup /var/apps apps
10 0 * * * root /usr/local/bin/backup /var/volumes volumes
