Hi guys!
This time I'm not posting because of an issue xD. This time I would like to ask if something is posible.
In my job, we want to make backups of the important data. Therefor , we want to have 1 HD in the office, doing incremental backup (rsync :D), and the other one outside the office for more security in case of fire, crash, bomb (?),... etc.
My idea is to make a RAID 1, and unplug one of the disks. Then, once a week (Fridays), we would like to take the unpluged disc and stick it to the nas, and have the DNS to make an autobuild of the data. When finished, remove it again, and take it home. But I don't know if that is possible. We don't actually have a DNS-323 at the office (I'm asking before I'm buying), so, if you don't recommend that option, could you please suggest me one?
Thank you !! :D

Hi topikito,
It's not recommended practice to remove a functional member (HDD) from a RAID solution. You will run into synchronization issues and likely lose your data.
If you are looking to "backup" (and I'm using the term very loosely) the data on the NAS, you would be better off purchasing a 2nd NAS and duplicating the content of one NAS to the other. Once the duplication is completed, you could take the 2nd NAS offline until it's time for another "backup".
Of note, RAID is not a backup solution ... it's a redundancy measure.
HTH,

Ok, thanks for replying

HTH,
Would it just be better to use a USB external drive to do the backups or am I missing something here?

You're not missing anything, it would be MUCH better to simply use a different drive. Once I stick the drives into the NAS, I don't tinker with it, just let it run!

I wrote a fun_plug script which formats and mounts an attached USB hard drive and copies the data from Volume_1 to the drive. It runs when the NAS boots if the USB drive is attached and turned on. It also creates a log file and unmounts the drive when it has finished. What would be better is if I could use rsync to do it. Is there an easy way to install rsync without installing FFP? I.e. a standalone file I can run.
