Backup Setup

(see doku/policy.md for general idea)

Preparation

  • buy two large external USB harddrives
  • format each drive (I use ext4)
  • set label to backupN, where N is the number of the disk. e.g.: 
    sudo e2label /dev/sdx1 backup1  # replace sdx1 by correct value

Initial Setup (as root)

(The scripts are tested with Debian "Buster" and borg 1.1.4)

  • checkout this repo to /root/backup
  • Adjust all paths (replace all occurences of nchiapol)
  • store the passphrase you want to use for your encryption-keys in the file /root/backup/borg-passphrase (Make sure its only readable by root chmod 400 /root/backup/borg-passphrase)
  • plug-in backup disk and run setup.sh
  • plug-in second disk and run setup.sh
  • add a cronjob for root crontab -e 
    15 21 * * * /root/backup/scripts/backup_home.sh
  • copy file helpers/10-udisks.pkla to /etc/polkit-1/localauthority/50-local.d and adjust Indentity to match the user used when mounting in the backup scripts

KMail Backups

  • create a directory to store the mail backups (e.g. ~/.mail-backup)
  • add subfolder archives
  • setup KMail's 'Archive Mail Agent' 
    Path: ~/.mail-backup/archives
Backup each: 1 Days
Maximum number of archives: 1
  • add (user-)cronjob to run helpers/unpack_archive.py for each account a few minutes before the backup_home.sh cronjob
