I have accumulated a vast amount of data (almost 8TB) in my personal collection. That being said, I have been neglectful in how it's managed and how it's backed up.
Currently, I have a custom built system (Windows) which has four (4) internal drives and four (4) external hard drives with a combined total storage capacity of about 12TB. The drives are not identical so RAID is not an option. Yes, I know, very sloppy. In addition, I have no back up policy in place and; thus, no way of recovering data in the event of a hard drive failure.
My goal would be to create a local backup of all data (inclined to use QNAP) and one off-site option. For the off-site (cloud) option, I was considering either getting a second QNAP and house that in another location or using a reputable third party cloud storage vendor.
I am considering getting two TS-420...
