Hi,
I'm wondering, will zfs diff work between two zfs pools?
No. Only between snapshots within the same dataset within the same pool.
I want to know if the current snapshot of my data differs from the
snapshot I created by "zfs send | zfs receive" while ago (on the same
machine, just different pool), so that I should refresh my backup.
Does 'zfs diff' read all the data in snapshot, or compares just some
checksums and thus is fast?
We do our best to only read meta-data in finding the differences.
