We just got home from 3 weeks at the MIL’s house. One of the first things I do when I get home is check my Nucleus backups and they were inaccessible. I use an attached 1TB USB HDD. Not only were the backups inaccessible, but the drive was not showing in Roon or Windows, but was visible when plugged into my laptop.
We had a power outage 6 days after we left home. The Nucleus rebooted but lost connection to Tidal and Qobuz, so Roon ARC would only play my 42 local files for the remaining two weeks we were gone. Needless to say, I was happy to have Apple Music for CarPlay.
I did several reboots of everything and was not able to get it working. I finally plugged the drive into my computer and reformatted it to exFAT and plugged it back into my Nucleus. All is working now and I have reestablished my daily, weekly, monthly, and quarterly backup routines. I also did a manual backup to each of these 4 folders.
I guess the power outage somehow took out the USB HDD, but all is good now.
EDIT: All scheduled backups worked last night as expected.
That sounds off, maybe download CrystalDiskInfo and check that drive for pending/reallocated sectors. If a reformat fixed it, I would guess that your hard drive is on its way out.
I would suggest you keep an eye on it. Power failures are bad for hard drive and sudden data corruption indicates early hard drive failure. I wouldn’t rely on that drive for something as critical as backups.
I have other backups on my laptop. I check my backups frequently. At this point, I don’t know that the data was corrupted. I lost connection and my solution was to reformat the drive.
That’s a start, but the only real solution is for Nucleus and ROCK OS to gracefully shut the Core machine down when the UPS detects a power failure and have the BIOS set to power up after power is restored.
That’s a shame, no ssh access? I’m glad I run my core on my unRAID server using the community supported docker container. For those of us technically inclined unRAID is a great NAS OS and it can run on any old hardware. It has APCUPSD built in so when I’m on battery for more than a few minutes my server will gracefully shutdown and then conserve the UPS power for my router and Verizon ONT so at the very least I can browse the web on my laptop for an hour or two while I wait for the lights to come back!
I finished charging for 8 hours and just plugged everything in. All is working as expected.
On the surge protection/battery side, I plugged in U-Verse router, Nucleus, backup HDD, and switch.
On the surge protection only side, I plugged in TV and U-Verse TV receiver.
Tomorrow, I will look at routing my incoming internet through the ethernet surge protection.
Unfortunately, the Cyber Power units are poorly designed. I had the same model ( CP1500PFCLCD). When the battery failed it cut power to everything connected to the unit (even on the protection only side). Also, had this happen to a different Cyber Power model.
Long as there is no data loss on any devices with hard drives. I got lucky when it happened to me. My desktop computer and NAS didn’t experience any data loss. Whole point of a UPS is to avoid putting devices like that at risk in the first place though so needless to say I was beyond irritated when I discovered (the hard way) Cyber Power’s fatal design flaw.
