What's probably happened, is that the auto-snapshot service has
dutifully destroyed snapshots that have reached their expiration, and
this has broken -R, which is trying to send those now-non-existent
snapshots.
I bet what you really want is 'zfs send -r f...@snap' which would send a
snapshot of all descendant datasets with an '@snap' snapshot, rather
than all snapshots of all descendant datasets up to '@snap':
unfortunately that command argument doesn't exist.
You could easily script this with:
# zfs snapshot -r mydata...@t1
# for ds in $(zfs list -t filesystem,volume -o name -r mydataset)
