Offsite Backup

Offsite Backup
Offsite backup services, also known as remote backup or online backup services, allow making data backups and storing them at a remote site, while providing access to the files from any location having the Internet connection.

Pioneer companies which offered offsite backup services made their appearance in late 1990s. Today the majority of online backup service providers use the SaaS (Software as a Service) model.

SaaS is a business model of selling and using the software such that the provider develops a web application and maintains it on his own, while customers purchase the right of accessing the software over the Internet.

The principal advantage of SaaS model for a customer is the absence of expenses connected with installation, updating and maintenance of hardware, and software running on it.

A payment is usually made in a form of yearly or monthly subscription fee depending on data storage capacity ordered.

Thus, offsite backup users are totally free from spending money on purchasing and upgrading their own storage systems. Using remote storage run by acknowledged, reputable providers may even significantly increase enterprise storage system security level in whole.

Online data backup services have a few common features. All of them are using Internet for transferring information to remote data storage, they suggest automatic backup while computer is idle, and allow scheduling backup creation during off hours.

System administrators can adapt data backup scheme for any particular machine. Recovery after disastrous situations as well as casual recovery from backups is also accomplished via Internet.

The distinction of offsite backup services lies in customer fee, speed and control options over remote backup modes. The majority of such services only transfer that portion of data which was changed since the latest backup has been made.

They also adjust data transfer rate so a backup service doesn’t take away the entire Internet channel bandwidth. The list of additional functions can be extended with data encryption, compression, and data deduplication options.
