best way to backup (lsio) docker jellyfin data?

[TheDreadPirate]

I had some hardware failure last summer and was able to restore from the backup made with this script.  No corruption.

Code:

#!/bin/bash

BACKUP_LIST=/root/backup_list.txt

while read list ; do
source=$(echo $list | awk -F ':' '{print $1}')
dest=$(echo $list | awk -F ':' '{print $2}')
rsync -a -r -p --progress --exclude /var/lib/docker "$source" "$dest" --delete >> /root/backup.log
done < $BACKUP_LIST

It reads in a text file that has a source directory to backup and a destination of where to place the backup.  If you delete or change a file in the source directory it will delete it from the backup directory (the --delete option).

Excluding /var/lib/docker is important because it only contains temporary data and takes up a lot of space if you don't exclude it.

An example of the text file specifying what to backup.  The colon separates the source (left) with the destination (right)

Code:

/home:/media/extended/Backups/
/etc:/media/extended/Backups/
/var:/media/extended/Backups/
/media/storage:/media/extended/Backups/media/
/media/storage/Pictures:/media/extended/Backups/
/docker:/media/extended/Backups/

In /etc/cron.d I created a text file that contains the cronjob schedule.  You can also put this in root's crontab.

Code:

0 3 * * * root /root/backup.sh
0 1 * * mon root cat /dev/null > /root/backup.log

This runs the backup script nightly at 3am.  Every Monday at 1am it nulls the backup log file.
