Remote RN104 btrfs corrupted (empty volumes)
Hi, I was running a RN316 (v6.5.1) smoothly at work and Replicate to a remote RN104 (6.5.2). I know I did not update the firmware but those versions were the most stable for me and it's hard to keep...
I received my UBS drive, any more advice before I start?

The backup of course is very important.
On the firmware upgrade, you should be ok (since the RN104 is running 6.5.2). You'll lose Replicate and Remote though (and am a bit surprised that they were still working for you). You can substitute rsync over ssh (with port forwarding or over a VPN) - configuring rsync to delete files on the destination that are no longer on the source. Though that doesn't provide versioning, you can set up custom snapshots on the RN104 to give you retention.
On the maintenance tasks - "balance" is specific to btrfs. Also the scrub includes both a btrfs scrub and a RAID scrub. I suggest setting up a schedule that runs all the tests periodically. Personally I run each test every three months.
On the RN316 - if you are using "smart" snapshots, you might consider switching to "custom", and setting a retention limit. The "smart" snapshots keep the monthly ones indefinitely - requiring manual deletion from time to time.

I already scheduled those tasks every 2 months and the unit is on UPS power, but it did not prevent me to loose all data from the RN104.
Thanks.
The end of service for Replicate was announced as being Jan 2018, though I believe it was then pushed back to the end of 2018. I understand Netgear has left it up for those still using it (I don't, so can't confirm), but does not allow new accounts or include it in the latest OS updates. They have not announced when it will really completely end, but you are going to lose it at some point whether you update or not. Unfortunately, ReadyDR, the closest to a replacement for Replicate, is not available on ARM platforms.
The Replicate end-of-life was cancelled as Neatgear does not have any alternative solution to existing users. I'm not really confident to start playing with SSH, Rsync and ZeroTierOne... :-(
