Yev from Backblaze here -> If you have a lot of data (over 4TB) I'd recommend a local NAS or a simple Drobo to hold the data locally in addition to Backblaze for the computer. If you get a NAS we're integrated with a few NAS vendors with B2 cloud Storage so you can also have those NAS systems directly moving data to B2 as well (separate cost structure - but good stuff).
