After testing mailcow for two months and learning a little about docker I’m ready to switch my primary email domain to mailcow. I have a few questions:
I plan to run centos8 for the host as I’m most familiar with it. I plan to mount a sufficient volume on /var/lib/docker
Should I go with ext4 or xfs? Centos 8 supports d_type
What is a good update strategy?
I assume I can enable automatic security updates on centos and update mailcow every few weeks or so before I automate it.
What about backup strategy?
I need /opt/mailcow-dockerized and /var/lib/docker/volumes
I can script a local backup. What would be a good strategy to pull backup from mailcow server and store it on backup server?
