Remote or online backup is a systematic way of storing backup and recovery data in an offsite location where folders, files and the entirety of a hard drive is copied regularly and is sent to the provider’s database over a network or the internet. It is also referred to as web based data recovery and backup.
Client software is at the heart of any online data backup. It runs daily on a set schedule and copies all the files that is set to be backed up. The process of collecting, compressing and transferring of copied data occurs simultaneously and is sent to the service provider’s data servers.

- Binary bits of data recently changed are transmitted by other remote backup providers.
The disadvantages on the other hand include:
- Data transmission and restoration depends on the internet connection and bandwidth. When something happens and connection to a network or the internet is slow. Tapes or labeled CD’s will be shipped from the provider.
- Guarantee that data will be kept private is not sure. It is always better to have data encrypted first before backup process is automated.
- Cost and access to data is at risk especially when a firm closes or is sold to a new owner.
- Loss of password for encryption will render all backup data useless and recovery will be impossible but proper management will be able to take care of this.
