(yes I know they rotate already... )
dns-321 installed and visible on network, now I need a backup strategy
I want to back up daily to a hard drive, then once a month rotate the drive offsite and bring back a previous drive to wipe and reuse. (there will be a permanent archive as well)

So is the best way to do this:
Use raid 1, keep 2 disks in, and at the end of the month (randomly) pull one disk and shove in an older one? This gives the goodness of raid 1, but I worry that when I plug an older raid-filled drive, it might overwrite the newer drive - i.e. how does the DNS know which raid drive is correct?

Or...format the unit as 2 drives, populate and backup to one, then at the end of the month put in a second reused drive and manually copy the data to it? This means during the month I don't get raid.

Is there a standard better answer for this? Must be a common question.

thanx

The best way is to forget about taking disks in and out of the NAS and simply have a separate USB connected backup disk that you periodically update.  You can have two of them that you swap periodically.  You are playing with fire continually taking disks out and putting them in, and the RAID takes hours after you stick a disk in to sync, performance is really poor during that time.

Thanx - sounds simple. I'll leave 2 drives in all the time in raid 1, and rotate offsite with a USB drive.

If you use a file sync application for the USB backup, you'll only have to copy changed files from the NAS to the drive, it'll save a bunch of time as a rule.
