UPS

[trailer]

We had a thunder/lightning storm here last night and the power went off briefly.
I have a Netgear ReadyNAS Duo which lost power. I turned it back on this morning and it has spent (and is still spending) all day doing a RAID sync. To save this happening again I guess I need a UPS.

Would something like this be adequate?

Lets hope that data is OK Trailer.

I use the slightly larger capacity APC .

This 550va one for NAS and router and other low power devices:

700va for desktop PC's so the monitor still works for a while in power failure:

I generally use known brands such as APC as I once had a cheapy unknown brand name from China start smoking during the night....that nasty burning component smell that set our smoke alarms off.
They where all recalled by amazon or ebuyer (cant remember) and refunded shortly afterwards...must have happened to a few people.


Remember to make regular backups of the data on your NAS as it will most definitely fail one day. ( happened to me recently)

I have always had my router and network switch on a UPS so that in a power failure I can save what I am working on as the network wont work without the router powered up, ( sure you know that but many people forget :) )

I was stung once by failed RAID drive and won't use one again. Better to take scheduled incremental backups to another standard drive. In a RAID system both drive and controller can fail. In a standard drive system only the drive can fail. It's one less thing to go wrong...

I hope your system is all good though once it's done it's thing. But it's probably worth thinking about the most reliable form of backup. Does your data change a lot over the course of the day, or is it fairly static? How much data would be lost if you did scheduled backups hourly, or daily, rather than dual writing via RAID?

As Nick says, RAID shouldn't be used as backup, it should be used only as a high availability (24/24 7/7) solution.

Well the Raid Sync operation finished last night and it seems that all the data is intact, Phew!

I'm using a Nexstar LX external NAS USB'd into an Airport Extreme for the main storage. The ReadyNAS does a back up job from that drive onto itself every few days, which itself is set up for X-Raid, so I'm hoping I have enough redundancy in case of a failure!

It was a PITA that I couldn't get onto the ReadyNAS during this operation which lasted approx 12 hours, hence the thought for a UPS. I must admit the only UPS that I am familiar with are the APC variety so I'll probably go and get one of the ones that Mark has suggested.

Thanking you all for the helpful advice.

That's the one I use. I've got three of them :)

Yep I use the 700va one too very good value for money.

Well I have an APC Back-UPS ES 700VA.

A bit more peace of mind. A nice touch is the unit has a USB to Ethernet cable supplied to install the APC PowerChute software. I can plug this cable into the USB socket on the ReadyNAS and the ethernet of the UPS and the ReadyNAS detects that it is running off a UPS. The ReadyNAS will then turn itself off when the UPS battery life drops. :eek:

There's even an app for it too:
