Not sure I understand how this subvolume is related. You send differences between Video_ro.20180205_21:05:15 and Video_ro.20180307_22:03:03, so you need to have (replica of) Video_ro.20180205_21:05:15 on destination. How exactly Video_ro.20180220_21:03:41 comes in picture here? > Name: Video_ro.20180220_21:03:41 > UUID: 2afc7a5e-107f-d54b-8929-197b80b70828 > Parent UUID: e5ec5c1e-6b49-084e-8820-5a8cfaa1b089 > Received UUID: 0e220a4f-6426-4745-8399-0da0084f8b23> > Creation time: 2018-02-20 21:03:42 -0800 > Subvolume ID: 11228 > Generation: 4174 > Gen at creation: 4150 > Parent ID: 5 > Top level ID: 5 > Flags: readonly > Snapshot(s): > Video_rw.20180220_21:03:41 > Video > > > Wasn't I supposed to set 2afc7a5e-107f-d54b-8929-197b80b70828 onto the > destination? > > Doesn't that look ok now?
