Still, if I were you I’d probably have cloud backup from Backblaze or something like that.
I don’t trust other people with my stuff. Two external hard drives to back my stuff up.
It’s the off-site part about cloud backup that I like. Protects against on-site property damage. Also, it automatically uploads changes to files without dicking around with backing up manually.
JEDIT: Although I suppose one could use bittorrent sync instead to backup to offsite, if that was the real issue. I use Backblaze for my server because it’s cheap, it’s easy, and available storage is unlimited (which is nice when I have 4.7 TB of data).
