A remote backup service or online backup service is a service that provides users with an online system for backing up and storing computer files. Remote Backup Service Providers are companies that the software and server space for storing files. Remote backup is similar to file hosting service; files are usually guaranteed not to be lost for a high premium.
Remote backup does not require user intervention. (The user does not have to change tapes, label CDs, etc.)
Remote backup maintains data offsite. Perhaps the most important aspect of backing up is that backups are stored in a different location from the original data. Traditional backup requires manually taking the backup media offsite.
The client runs a scheduled software program (typically once a day). This program compresses, encrypts, and tarnsfers to the remote backup service provider's servers.

Disadvantages of remote backup
Remote backup has some disadvantages:
The restoration of data can be slow, though today's increasing broadband Internet connections are rapidly removing this disadvantage. Because data are stored off-site, the data must be recovered either via the Internet or via tape or disk shipped from the online backup service provider. Sometimes systems capable of bare-metal restore are preferable.
It is possible that a remote backup service provider could go out of business or be purchased, which may affect the accessibility of one's data or the cost to continue using the service.
