HDD rotation for security backup

[joergstockinger]

Hi *.*
I use a NAS AS5102T for all my privat data (Pics, Music, Docs etc.) with two 2TB HDD in level RAID 1.
For security reason I will rotate one of the two HDDs every month to store the HDD on a different place (security backup).

What do I have to consider for this action?

Many Thanks.

Kind Regards

Joerg

Do you mean you own 3 disks in total:

• Disk A and B in RAID-1 in sync state.
• Power NAS off. Remove disk A.
• Power NAS on. Insert disk C. NAS will re-sync.
• Bring disk A to other place.
• Replace disk B with disk A by the previous way on the next month.

If yes, that's all right for the complete backup. However I won't do that (because of many drawbacks).

Hi Orion,

many thanks for your reply. You are right with your steps.

What kind of drawbacks may occur?

From data security perspective I need a backup outside of my environment.
What is the best security plan to do so?

Kind Regards

Your way will do full backup copy each time. And you'll need to do backup actions (power off, on, plug disk, bring disk, ...) manually. I would prefer to simply setup a backup task, then I'm free to do other things. And the backup task should be incremental backup. That means I would setup another NAS on other place and setup rsync backup task with secured connection.
