This is some test data simulating snapshots on a source and target machine's
zpool. If processed correctly, it should result in several zfs send commands
which would bring target up to date with source.

Contains three test datasets
   files_share
   iscsi
   nextcloud

each contained in paired files of the form dataset.(source|target).test.data

files_share and nextcloud have children datasets while iscsi has none

files_share has inconsistent snapshots (storage/files_share/nfs has no snaps
for 12/14 or 12/15) so should generate sends for each child dataset

nextcloud is completely consistent and should generate one send command
with the -R parameter
