Upgrading Disks and Reshaping Time
Hi My ReadyNAS has 2x1TB and 2x4TB drives in it. I just purchased 2 more 4TB drives to replace the 1TB drives as I need more capacity. I've swapped in a 4TB drive to replace the first 1TB...

So what is your solution?
Only one I can see is to have 2 duplicate NAS's
That is what I do. My main NAS is a pro-6 with a 15 TB RAID-5 volume. I have two backup NAS - an RN102 and an RN202, both with 6 TB + 8 TB jbod (two volumes on each). I learned pre-nas that it was wise to have 3 copies of everything I care about.
I also use crashplan cloud backup for disaster recovery, but I am not so confident in any cloud backup to rely on it completely. At some point I might drop one of the backup NAS and rely on crashplan (or amazon cloud) for the second copy.
I think another option is to use 8 TB usb drives (though you'd need two of course). If a lot of the data is archival, you could use a Seagate SMR drive for that.

And I do backup my critcial data, just not all 16TB.
If you have the ability/discipline to separate criticial and non-critical data, then that's a great way to reduce the impact.
I find its difficult to keep "critical" separate from "non-critical" myself. So I just back up everything.
First it had to add the disk into the 4x1TB array, now it is adding it to the 2x3TB disk array to create a 3x3TB array so the volume can then expand.
You must wait for the resync to complete and the volume status to return to a redundant state before replacing the next disk. Please be patient.
If you try replacing another disk before the reshape completes your volume would go offline. Don't try this.
Not sure where the 4x1TB, 2x3TB and 3x3TB references are coming from as the 4 slots only contain 1TB or 4TB drives and no sign of any 3TB ones!! :0)
Original starting configuration:
Slot 1: 1TB
Slot 2: 1TB
Slot 3: 4TB
Slot 4: 4TB
At the moment it is sync'ing with one disk inserted
Slot 1: 4TB
Slot 2: 1TB
Slot 3: 4TB
Slot 4: 4TB
I will end up with this when last disk is inserted.
Slot 1: 4TB
Slot 2: 4TB
Slot 3: 4TB
Slot 4: 4TB
