In the original RHEV instance - there were 3 storage domain
i) Hosted engine storage domain: engine
ii) Master data domain: vmstore
iii) An export domain: expVol (no data here)
To my backup RHEV server, I only imported vmstore.

No - there was no file with this id (checked both in the original RHEV
instance)
[root at dhcp42-105 mnt]# pwd
/rhev/data-center/mnt
[root at dhcp42-105 mnt]# find . -name 6f4da17a-05a2-4d77-8091-d2fca3bbea1c

No. The only operation done was creation of a snapshot - and it
completed before the recovery was attempted.
