Hi,
There are several ways of keeping your data safe. You can look into MaxxDigital, they have great solutions. The Evo2K is an excellent choice for the workflow you are talking about. You can also look into LTO for Backup. Cache-A is a nice appliance, just plug and play, and LTO4 drives can take upto 800GB, LTO5 1.5TB and last more than 30 years.
Hope this helps.
