Feature Suggestion: Automatically create/delete LVM, ZFS or Btrfs snapshot Well, currently I don't have any servers.
At the moment, I have a desktop computer that dual boots Windows and Ubuntu 18.04 LTS. Ubuntu is currently just using an ext4 partition. I am considering reformatting the root partition to either an LVM PV/LV, or Btrfs, for snapshots, still with Ubuntu. Probably use LVM with Ubuntu, as that's easy to setup out-of-the-box with Ubuntu.
I have used SuSE and OpenSuSE at work - they have very nice Btrfs integration, including a snapshot management system called snapper, although Ubuntu does NOT have snapper, but it will work with Btrfs.
ALSO, I am running an experiment of sorts - I have set my fiance's mother up with Linux Mint, with LVM (because I wanted to have snapshot capability for making consistent backups). If I like Cloudberry, I might try setting her up with Cloudberry for backup. If I find I can get her working well with Mint or Ubuntu, I may try convincing some of my other relatives to let me get them setup on Linux.
I think, for simplicity sake, I'd probably mostly have them on Either Mint or Ubuntu with LVM. So, for what it's worth, that's where my vote for first support would be.
