While I would have preferred Cent OS, OpenMediaVault uses Debian and I'd prefer a standard installation.
I abandoned Nextcloud because frankly it's too complicated for what I want. ssh and radicale fulfill 2/3 of what I use Nextcloud for.
The last 1/3 is photo backup. This is the one thing I still haven't figured out.
Every forum post I find recommends Nextcloud, but I just abandoned that, so I don't want to use it.
I chose OpenMediaVault as an easy way of setting up something like ZFS or RAID, still haven't decided but I haven't bought new hard drives yet, so I'll have some time to think about it.
