OS: Unraid (Nvidia) 6.8.3
Plex Server: 1.18.9.2571
My daily Plex backup exceeded 4 hours now and is running way to long. Before I ask what might be left out, here comes some info about my systems:
The Plex Server runs as a LinuxServer.io docker container on a very fast NVM M.2 BTRFS RAID1 (Unraid cache pool). Every night I stop the docker container at 4:00 to take the backup. As I’m really strict on backups I do not only copy the Plex appdata store, in addition I copy individual files. The first and daily backup goes to the Unraid array at 50-60MB/s (dual parity). A second and a third backup go weekly and monthly to a second and third Unraid backup server. Here are the commands for the daily backup:
# Stop docker
docker stop plex
# Daily sync of the complete plex appdata store (without Cache, Logs and Crash Reports)
# from the Unraid Cache pool to the Unraid Array pool
# This is running way to long because it happens while Plex is stopped
rsync -avPX --delete-during --delete-excluded --exclude="Cache/" --exclude="Logs/" --exclude="Crash Reports/" "/mnt/user/system/appdata/plex/" "/mnt/user/Backup/unRAID/appdata_backup/plex/"
# Save Plex preferences to a separate backup folder
cp /mnt/user/system/appdata/plex/Library/Application\ Support/Plex\ Media\ Server/Preferences.xml /mnt/user/Backup/unRAID/plex_backup/
# Save Plex SQLite DB to a separate backup folder
cp /mnt/user/system/appdata/plex/Library/Application\ Support/Plex\ Media\ Server/Plug-in\ Support/Databases/com.plexapp.plugins.library.db /mnt/user/Backup/unRAID/plex_backup/
# Dump View Statistics from Plex DB to a separate backup folder
echo ".dump metadata_item_settings" | sqlite3 /mnt/user/system/appdata/plex/Library/Application\ Support/Plex\ Media\ Server/Plug-in\ Support/Databases/com.plexapp.plugins.library.db | grep -v TABLE | grep -v INDEX > /mnt/user/Backup/unRAID/plex_backup/settings.sql
# Dump Plex SQLite DB to a separate backup folder
echo ".dump" | sqlite3 /mnt/user/system/appdata/plex/Library/Application\ Support/Plex\ Media\ Server/Plug-in\ Support/Databases/com.plexapp.plugins.library.db > /mnt/user/Backup/unRAID/plex_backup/dump.sql
# Start docker
docker start plex
So my question is: What can I leave out in the rsync task? The huge amount of metadata in the docker container is killing me. As you can see I store configuration settings, SQLite DB and view statistics. What is really really required without losing to much?
Any hint is highly appreciated.
Many thanks in advance.
