Thank you OP for sharing your discovery! And the DH response to your support inquiry.
I checked my own account(and will be checking on others - both personal and biz) and found that one user doesn’t even have .snapshot directories(anywhere). This is a change that happened sometime in the last 3-4 months since I last checked filesystem backups.
Interesting. Very good to know, especially in advance of the upcoming cluster move. And always a good datapoint for comparison. No cheap host will guarantee backups but it’s certainly true that some do better than others at delivering it…
Thanks again for sharing the heads-up!
