How to backup a NAS? by alegator on 11-04-2011 at 11:01 PM
Hi, I'm starting to research as to how to setup a home NAS. From what I've read most NAS that are sold can be accessed via ethernet, wireless or USB2, all of which are too slow to backup say an 8Tb NAS. So what's the fastest and most inexpensive way to back it up? Thanks.

If you set your NAS with RAID 1/5/6 and have some unused spare disks at hand, then you shouldn't have to worry about backing things up since when one disk fails (two with RAID 6) you can replace it with the spare disk without losing your data.

Aka, what would be the best and fastest way to completely backup your NAS on an external storage?

When I mentioned "Backup" , I meant an identical bit by bit copy of your entire NAS to an external location, sort of like when you clone a hard disk to another physical drive.

Do you really need a bit by bit clone? Why not some kind of intelligent backup? I backup my NAS to a server, and it just checks for changed files and uploads only those each day, and over a 3 mbit line, no need for huge speeds.

Menthix, I guess that the first time you need a total backup, and then you can do incremental backups as you say. By the way, what is your NAS and server hardware? and what backup software do you use? Just to have some feedback, thanks

I have a Synology, DS409+ I believe. They make pretty nice devices. The backup is done through a regular pc with SyncBackSE. The server happens to be a Windows box too, but but can be any FTP/SFTP.

There are lots of ways to do this.
