Backing up koha

Hello,
How can we back up the files in koha? I noticed that the program does not have a backup tool so we can save the stored files. How can we back up so that we can not lose the database in the future?

I didn’t find the right solution from the internet.

Hello,

You can use the koha-run-backups command. This command will generate a koha system backup and a database backup. By default, the backup will be stored in the /var/spool/koha/instancename directory and will be stored for 2 days (that means yesterday backup and today backup).

You can also change the default configuration. For that, see reference Commands provided by the Debian packages - Koha Wiki
