Possible to keep auto logging in from clients after full server reinstall?

[TheDreadPirate]

Here is what I did to backup and restore my Jellyfin completely.

Code:

mkdir -p /path/to/backup/drive/jellyfin
cd /path/to/backup/drive/jellyfin
mkdir jellyfinEtc jellyfinVar jellyfinCache
sudo rsync -a -p --progress /etc/jellyfin jellyfinEtc/
sudo rsync -a -p --progress /var/lib/jellyfin jellyfinVar/
sudo rsync -a -p --progress /var/cache/jellyfin jellyfinCache/

NOT putting a slash at the end of the SOURCE path is important.  Without the slash rsync will pull the entire directory, including hidden files and folders.  If you put a /* at the end of the source path it would not grab hidden folders and files.

To simulate a fresh OS install

Code:

sudo apt purge jellyfin*

To reinstall

Code:

curl https://repo.jellyfin.org/install-debuntu.sh | sudo bash

To restore

Code:

sudo systemctl stop jellyfin
cd /etc
sudo rsync -a -p --progress /path/to/backup/drive/jellyfin/jellyfinEtc/jellyfin .
cd /var/lib
sudo rsync -a -p --progress /path/to/backup/drive/jellyfin/jellyfinVar/jellyfin .
cd /var/cache
sudo rsync -a -p --progress /path/to/backup/drive/jellyfin/jellyfinCache/jellyfin .
sudo chown -R jellyfin /var/lib/jellyfin /var/cache/jellyfin /etc/jellyfin
sudo systemctl start jellyfin

None of my clients had to re-login.
