Please how do I handle a backup in my library?

This depends on the kind of backup you want to create. I suggest the following: 1. Read the sections on the commands "koha-dump" and "koha-run-backups" here: https://wiki.koha-community.org/wiki/Commands_provided_by_the_Debian_package... In a Koha standard installation the command "koha-run-backups" in "/etc/cron.daily/koha-common" is running by default: koha-run-backups --days 2 --output /var/spool/koha So you will finjd your daily backups in directory "/var/spool/koha/<instancename>". 2. Watch this video by RAFLIMTS: Koha backup & alternatives: Backup Koha before version upgrade https://www.youtube.com/watch?v=gLcZWEAW6fA Hope this helps.
