Thank you for the script! I've modified somewhat it so that:

1. Now EXCLUDES the /Cache directory (that was trickier than expected) which for me saves ~700 mb of space per backup.
2. Also updated log to append so log is a continuous track of when and what.
3. Also updated as I have both a READ ONLY mount and a READ/WRITE mount, so now the R/W share is ONLY mounted at run time of script (me and my “this user should ONLY ever have READ access to my media” paranoia… lol)… NOTE: this also then requires the /mnt/buplex share to have the “noauto” option in /etc/fstab file…
4. Creates a different backup file via TAR each time, vs using RSYNC (which I found walking my tree rather slow and painful, and I want separate DB backups in case DB gets corrupted somehow... I don't to overwrite a good backup with a bad one etc).
5. Possibly a few other tweaks I'm forgetting. Sorry.

NOTE: the LAST bit of the file (unmounting R/W share) happens AFTER logging and r/w access to the log file (in my setup) ends... so NO ERROR will be caught if unmount of r/w mount fails. Move your log file somewhere else if this concerns you more than me (ie, you set this up to be automated, not manually run) ;-)

Some of the above others probably don’t want or need, but just FYI might prove useful (and as a note to self for my own future sanity!)

Tested on Linux Mint 19 Mate, works great

Can you add the feature to delete Backup-Version there are older then like 14 versions?

Create another bash file and add the following then run a cron weekly to keep things tidy, this is set to 10 days but depends how often you backup.

#!/bin/bash
#Name:
#Author:
#Date:
#Description: Cleanup files older than 10 days inside DIRECTOR_TO_CLEANUP

DIRECTORY_TO_CLEANUP="/mnt/buplex/Archive/Plex_Backups"
LOGFILE="/home/cleanup.txt"

/usr/bin/find ${DIRECTORY_TO_CLEANUP} -type f -mtime +10 -delete >${LOGFILE} 2>&1

Sadly I have a huge /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Media folder that rsync and tar got killed within the process to backup that 'Media' folder.

Any other idea?

tar -zcvf is running for a while and it gets killed:
