We have around 50 linux clients with borg backups to two different
backup server, provisioned with Ansible. A new host is in the backup in
around 30 seconds :) One backup server is internal for DMZ and LAN and
one is for external hosts. The internal backup server syncs its backup
to the external server. Storage is made with ZFS summed up to 16 TB each
server.

This runs nicely for around two years without interruption. We learned a
bit her e and there about some side effects with borg cache in the
beginning and invested some time in hardening and Ansible role.

Before we choosed borg restic was on the list. Looks good too. Do not
now anymore why we decided for borg. Maybe the name :)
