Does anyone here have experience with backing up ZFS pools in cloud storage like S3, B2, ...? I have a bunch of snapshots (https://github.com/jakelee8/zfs-auto-snapshot https://github.com/jakelee8/zfs-auto-snapshot) that I want to backup along with the active tree. But don't want to keep extra copies of the data. - Do these services offer snapshotting? ...that can be automated? - Is there zfs integration, e.g `zpool send | b2 receive`?
