My 5-ish TB of data over at Crashplan begs to differ (and yes, I have a local copy as well).
Mirrored drives are not a good idea for data protection - for one thing an accidental delete (or overwrite, or ransomware, or whatever) will take your data out completely and instantly. Much better to do incremental backups at the file level, so you can restore deleted or damaged files from whenever you want in their history. Even if you don't want to pay for the cloud service, the crashplan software will do this very nicely to any target server.
