Hello again!
Unfortunately the script I wrote in my message yesterday in certain cases did
not detect ongoing backups. I have therefore made an additional SQL check for
this. Please use the updated script below instead. It works for me, but you of
course use it on your own risk.
Best wishes,
Thomas

#
# PURPOSE
# Bash script to purge old Bareos volumes both from the Catalog of Bareos as
well as from physical disk,
# as Bareos unfortunately does not delete old AlwaysIncremental volumes of type
VirtualFull automatically.
#
# DISCLAIMER
# This script is used at your own risk, without any warranty whatsoever!
#
# USE
# First save the script as /usr/local/bin/bareos-purge-old-volumes.sh
# Then make it owned by root and the group bareos and make it executable:
# chown root.bareos /usr/local/bin/bareos-purge-old-volumes.sh
# chmod 770 /usr/local/bin/bareos-purge-old-volumes.sh
#
# Then make the script run as a Bareos job:
#
#Job {
# Name = "PurgeOldVolumes"
# Type = "Admin"
# Description = "Purges old volumes left behind from AI consolidations"
# Schedule = "DailyPurgeOldVolumes"
# JobDefs = "DefaultJob"
# Client = bareos-fd
# RunAfterJob = "/usr/local/bin/bareos-purge-old-volumes.sh"
# Priority = 31 # run after consolidation
# }
#
# Also make a new schedule for the job, which should be prioritised below the
priority of the Consolidate job
# and ran for example one hour after the Consolidate Job:
#
# Schedule {
# Name = "DailyPurgeOldVolumes" # Purges old volumes left behind from
AI consolidations (priority 31)
# Run = Incremental mon-sun at 13:00
# }
#
# REQUIREMENTS
# Bareos version 16.2.5 or later installed with PostgreSQL as databse
# Bash
#
# PLEASE NOTE
# In order for this script to delete old volumes from disk you may need to set
these 3 directives in your Bareos Pool directive(s):
# Recycle = yes # Bareos can automatically recycle
Volumes
# Auto Prune = yes # Prune expired volumes
# Action on Purge = Truncate # Delete old backups
# Please read more about these directives in the Bareos manual at
https://docs.bareos.org/ to understand them before making these changes.
# If you choose to set these 3 directives, then update old volumes with the new
settings from the Pool(s) through running bconsole:
# bconsole <Enter>
# update volume <Enter>
# 14 <Enter> to choose 14: All Volumes from all Pools
