EBS snapshot backups from a FreeBSD zfs file system: zpool freeze?

For starters, I suppose very few people are using FreeBSD on AWS, so
"most of us" don't have a choice :-)

But this might simply be my understanding: what if I want to use the
EBS snapshot of the 5 disks I've taken and attach them to another
machine, and mount it?

But perhaps you don't know what an EBS snapshot is? It's not a backup
of your file system, it's a hardware-based backup of a disk at a
single point in time.


I.e. with EBS I can take a snapshot of 5 1TB, create new disks from
it, and attach it to another machine. In SECONDS.

I'm not looking for a way to take a ZFS snapshot, stream that to S3
for hours, and stream it back and write to another disk for hours.


But in case I didn't get you: could you please let me know if your
approach would allow me to take a consistent backup of my disks and
mount them on another server or use them for recovery purposes?
