Online backup is the use of a third-party service to back up data remotely over the Internet. It is a safeguard providing data management and protection for individual users as well as businesses.
Online backup is also known as remote backup, Web backup, Web-based backup, net-based offsite backup and other similar phrases.
The major advantage of an online backup system compared with a local manual backup is that the data is stored offsite. When files are backed up locally, whether to a file server, external hard drive or other device, there is always the risk of both copies being lost.
Formerly, it was mainly larger companies that could afford the cost of having an offsite backup. With the prevalence of cloud computing, cheap bandwidth and the decreased cost of storage, a solid backup system can be affordably created by both individuals and small businesses.
