I moreso meant if Enhance was built around using ZFS for a ZFS snapshot backup sytem etc. Enhance's backup system is good (MUCH better than Acronis on cPanel), but incremental ZFS snapshots are still vastly more efficient. It would be a huge architectural change, but it would be nice if Enhance was built in such a way from the beginning.
I've been working on a custom daemon (specifically for WP hosting) that uses FreeBSD Jails and using ZFS Snapshots means backups take up next to zero space and restore instantly, and use barely any resources to create. There are limitations and downsides but they are worth it for such an application imo.
ZFS does have a level of CPU overhead too but it's worth it, and being able to easily enable ZSTD compression is nice.
