I have a Qnap TS231 NAS with 2 x 4TB WD red drives in a striped array I use for most of my file storage.
I also have 2 x 4TB Seagate green drives that have been sitting in my gaming computer as a software dynamic disk backing it up once a week using a scheduled robocopy script.
Thing is I don't really like using the gaming machine for that purpose and it's the only PC I have with drive bay space to do it so I'm looking for some way to have it all happen without the PC being involved.
I put the 2 Seagate drives into a 4 bay USB 3.0 drive enclosure I have and plugged it directly into the NAS but that failed (after a few hours), I believe the enclosure is faulty and this last attempt at using it seems to confirm that.
Currently I have the 2 drives in a dual bay USB 3Dock which is not Ideal, they have to be formatted as individual drives and it's really slow. Currently it looks like it'll take about 4 days to do the initial backup of around 3.5 TB
So, any thoughts on how best to achieve this preferably using the 2 drives I already have? A new dual bay enclosure possibly with RAID functions?, 2 single enclosures for simplicity and price?, put the disks back in the PC and live with it?, a second NAS ?(pricey), find an old low power PC to use just for that?, something else?
I'm not concerned with separating the backup to another location, nothing on it is really that critical. I just like to have a backup to prevent me losing stuff due to stupidity on my part or a hardware failure. Don't bother suggesting RAID solutions, RAID is not a backup.
