So we recently acquired a customer that uses datto backups with an on premise box that replicates to the cloud . Fantastic solution and so far we have had zero complaints.

Until today we noticed the Ubuntu on prem box hasn’t checked into prtg (onboarding mode was enabled - 100% my fault and a good spot from my colleagues)

Spent an hour or so troubleshooting the basics , and in the process decided to reboot it to see if that would help ( 90% of problems are fixed by turning it off and on again amirite)

So we see a handful of pings during what we assumed was the reboot then nothing .. weird … really weird

I’ll save you the saga of us checking things like firewall rules which quite frankly we knew were not the problem as we hadn’t changed them

We ended up giving their support a call and was basically told yeah , no more icmp and no your not getting it back . Big sad

In all honesty I get it .. just annoying that I know have to figure out monitoring for these backups that does not rely on email and I was quite happy to leave this thing as a set and forget device considering how good the rest of the system is as a whole

TLDR: datto on prem device firmware update has disable icmp pings and it wasted a few hours of my day
