Dell PowerEdge C2100 with 24 Drive bays

Ha ha, no not really, but that is a great way to think about it.
-
So really my only choice would be something like a R720XD.
Loaded with 12 6TB SATA drives in RAID 10.

Would you need RAID 10 for this? Maybe RAID 6 would work for this use case?
-
It's a matter of reliability.
Using consumer grade SATA drives RAID10 seems to make more sense, doesn't it?

Why not an R510, much cheaper.
-
Plus moving as much data as we have off weekly the write speed gain would be worth it.

Check the price of RE drives in RAID 6. Might be cheaper with 12 drives.
-
Western Digital Red's at 4TB (12 in total) would cost ~$1800.
At RAID 6

At RAID 6
So WD Red (Consumer 5400 RPM) for 24TB is $1800.
-
WD RE (Enterprise) in RAID 6 would be 30TB for $1884.
-
So Red would be just barely cheaper, RE would be just barely larger. Red would be faster for random writes. RE way faster for reads.
-
If you went for smaller WD RE drives (2TB instead of 3TB) you could get 20TB usable for just $1,380.
-
For everyone's reference:
WD Red is consumer, 5400 RPM
WD Red Pro is consumer, 7200 RPM
WD RE is enterprise, 7200 RPM -
The trouble is at 24TB for backup there isn't much room for growth with this backup solution
So larger drives would be needed.

Then going to 30TB would be good.
-
If you splurge to $2,352 you can leap to the 4TB RE drives and suddenly you have 40TB to work with!
-
Now that remains SATA. If you are worried about performance the 4TB WD RE SAS drives will give you a huge boost in random access and only cost $2,436. Now that much more.
-
And, of course, to overwhelm you with options, you could get WD RE 6TB drives and get 8 of them. This would be much slower and give you 36TB today in RAID 6. But over time you could grow up to 60TB in that setup. Up front 36TB cost would be $3,280.
-
So 3TB Drives RAID 6.
No write performance though from the RAID.
Off Hypervisor, over the internet at 5841GB (30MBps pipe Asymetric) ...
Weekly.... would take 21 Days to perform a single backup operation... (roughly) -
I'm thinking our internet performance would have to take a huge leap as well for off site.
