Your tool does not create .snapshot subdirectories in EVERY directory like
Netapp does.
Example:

framstag@fex:~: cd ~/Mail/.snapshot/
framstag@fex:~/Mail/.snapshot: l
lR-X - 2017-09-09 09:55 2017-09-09_0000.daily -> /local/home/.snapshot/2017-09-09_0000.daily/framstag/Mail
lR-X - 2017-09-09 14:00 2017-09-09_1400.hourly -> /local/home/.snapshot/2017-09-09_1400.hourly/framstag/Mail
lR-X - 2017-09-09 15:00 2017-09-09_1500.hourly -> /local/home/.snapshot/2017-09-09_1500.hourly/framstag/Mail
lR-X - 2017-09-09 15:18 2017-09-09_1518.single -> /local/home/.snapshot/2017-09-09_1518.single/framstag/Mail
lR-X - 2017-09-09 15:20 2017-09-09_1520.single -> /local/home/.snapshot/2017-09-09_1520.single/framstag/Mail
lR-X - 2017-09-09 15:22 2017-09-09_1522.single -> /local/home/.snapshot/2017-09-09_1522.single/framstag/Mail

My users (and I) need snapshots in this way.
