Description Felix Botner univentionstaff 2020-11-10 11:27:38 CET 
+++ This bug was initially created as a clone of Bug #51765 +++

Frequently customers notice strange behaviour which is caused by no more disk space available.

Besides of logfiles customers are usually NOT aware of our build-in backup procedure and therefore loads of unneeded backup data is located at /var/univention-backup.

I never experienced a customer wanting to roll back a full year or more!

Customers not monitoring the free space will likely fail at some stage as replication will suddenly fail and other errors. They call support then.

In order to prevent the outdated backups to fill up disk space we should *by default* limit the backup files to 365 days.

So the variable should be set even on all already installed hosts (when not set otherwise).

backup/clean/max_age=365
