Keeping a remote hard drive up to date requires regular coordination and is not especially convenient. More recently, cloud storage has addressed the issue, although most companies typically offer just a few gigabytes.

A while back, flickr increased its capacity to 1TB and now Microsoft is offering unlimited OneDrive storage to Office 365 customers.
