Move from 6x2TB to 6x3TB

InterClaw - about two weeks ago while responding to a members post, I looked at a Pro 6 listing and they had a super deal. I have basically set it up with a spare 1TB drive and discovered it was running 4.2.15 so I updated and it is a sweet machine. (I think they were rotating their stock).

It sounds as if you already have the drives (WD30EFRX drives are hard to get right now) so if you have the resources to purchase the Pro 6 I would do so, and use your Pro as a backup unit. Normal backups with a very large array (your current array is 10TB gross) and with 3TB drives and single redundancy it would be 15TB gross. It will take a lot of external drives and a days to back up that size volume. Instead, you can set up a backup job using NFS to copy all the data over to the Pro 6 (after a factory default with all drives present) and then convert to rsync to verify the backup. You can then update the Pro, perform a factory default and then set up the backup jobs on the Pro 6 to copy the files back for backup purposes.

I currently have in operation two NVX units (two years old) and every night my primary automatically rsyncs all the files to the backup unit. Now that I have the Pro 6, I will have to use the two NVX units as backups, each backing up part of the Pro 6. It is a great comfort, knowing that if something goes wrong on my primary, my data is still secure. (My critical financial and important files such as photos and videos that are not replicated elsewhere is copied periodically to an external drive and stored offsite (in case a disaster takes the house).
