It depends on several crucial points.

1)      For how long do you need 50 TB (months, a year, several years, for-ever)

2)      How quickly do you need to retrieve

3)      Reliability

4)      Sensitivity


4-> Depending on WHAT you are going to store, it might be that you are simply not even allowed to store it in some cloud

2-> Tape might be an option, if you can wait a day or so J

1-> This defines your financial break-even-point

If it is for a short while, you might look for external storage,

But when paying hundreds per month, for several years…


When you think of local (self) storage, you should definitely look at CEPH-cluster technology: reliable storage, affordable, and master in scalability

With 5 machines as OSD, each holding four 6TB-drives, and a couple of monitors, you could get away with it

I think DIY is the best route. While some corporations are willing to risk having their data exposed (FB/Cambridge Analytical et al. ) and others can pay the financial price for having their data seen by others, it always boils down to what you want to deal with more (or less)....the amount of times you'll have to explain how some cloud provider screwed up?....or the reliance on your own backups...on your own schedule..and secured through means which fall a little more under your control.

Just sayin'...
