Snapshots have disappeared
I upgraded this morning to 6.9.5, and I noticed that all my snapshots have disappeared. I don't know whether or not this disappearance is a result of the upgrade.
Quotas are enabled.
Disk spin-do...

Also, were I to run a btrfs scrub from the shell, would I be crossing any lines with respect to future support from Netgear?
General guidance from Netgear is that support won't help you if they decide that your use of ssh did damage. If there was damage, then doing a factory reset would resolve it. https://kb.netgear.com/30068/ReadyNAS-OS-6-SSH-access-support-and-configuration-guides
Personally I don't think doing a btrfs scrub would do damage (since the scrub in the web ui includes it). But I don't work for Netgear, and their views might differ.

Honestly, I don't think there is a correct order. I run them all periodically (on a three month schedule), so the cycle could begin with any of them. FWIW my current schedule is
- disk test (month 1 of the quarter)
- balance (month 2 of the quarter )
- defrag (middle of month 2 of the quarter)
- scrub (month 3 of the quarter)
Are you using smart snapshots or custom settings?
What firmware were you running before you upgraded to 6.9.5?
I am using Smart Snapshots, set to "Weekly".
P.S. Previous firmware was the previous version -- 6.9.4. I generally update when the new firmware is released
Are new scheduled snapshots being created?
FWIW, I updated my backup NAS to 6.9.5 recently, and I didn't lose any snapshots.
