DrivePop offers its DrivePop 512GB 1-Machine Lifetime Backup for $49.99. That's the lowest price for any lifetime backup option we've seen from DrivePop since November. (We listed a two machine plan for $90 in May.) It features unlimited backup space, unthrottled bandwidth, "military grade" AES-256 encryption, and online streaming of music and movies. It's good for use on one computer.

Of note, you can upgrade the 512GB license to unlimited for an additional $39.99 during checkout, $89.99 total.
