Question

Nas drive backup

Jul 9, 2016 5:20PM PDT

Hi guys

I'm having some issues regarding my qnap ts 453a nas. My nas acts as my media server and to backup my phone. The problem is I have over 20tb of videos in true hd (some movies like avatar are 50gb and some tv shows like top gear are 239gb) and if I was to put the hdds into raid 1 my 32tb nas wouldn't be able to do it.

1) would an expansion unit, another nas drive or my pc allow me to rtrr backup to them? If so how would I set it up so that all the files on my nas are replicated identically on the the backup?

2) can I put the backup drive whatever it is in to sleep mode, auto wake up when files are added/deleted/changed backup them up and then go back to sleep mode?

3) what battery/ups would work with my nas?

Basically what I want is a off site backup of all my videos but I don't want it running 24/7 only when changes are made to the files.

Thanks for reading and any help will be much aporeciated

Odd to choose RAID 1.

My experience is that data errors are then instantly copied and the content is lost. Have you talked with anyone about this?

As to backup, Qnap should be answering most of these questions but for battery backup, there are too many good UPS systems out there. I can't guess the number of hours you want.

The biggest problem I find with folk that have such large file servers is they usually have no backup. And to do it right you would have 3 copies so you never exit the backup state.

Hi Thanks for the reply.

I have contacted qnap over a week ago still waiting for a response.

The reason I choose raid 1 is so all the same data is backed up exactly the same. So if I loose the main hdd no problem replace it withe the back up, get another hdd, back it up and I can carry on

I guess you have to experience the RAID 1 issue.

For me the issue of how a corrupted file or other item instantly corrupts the other drive has happened more often than a drive failure so for me, RAID 1 is a liability, not an asset.

I've also found poor implementations of RAID 1. It's very easy to test such a setup. You get it all working then safely shut down then remove a drive from the array. Remember I have seen good RAID systems over the years and the good RAID 1 will still operate but flag that it's in degraded mode in need of attention. So many RAID 1's just fail and want attention rather than keep on working.
