Managed backup providers are companies that provide this type of service.
Online backup systems are typically built around a client software program that runs on a schedule, typically once a day. This program collects, compresses, encrypts, and transfers the data to the remote backup service provider's servers. Other types of product are also available in the market, such as remote continuous data protection (CDP).
Providers of this type of service frequently target specific market segments. High-end LAN-based backup systems may offer services such as near-realtime transaction-level replication or open file backups. Consumer online backup companies frequently have beta software offerings and/or free-trial backup services.
History
Most online/remote backup services came into existence during the heyday of the dotcom boom in the late 1990s with the exception of a few early pioneers like industry originator Rob Cosgrove, CEO of Remote Backup Systems. While the initial years of these service providers were about capturing market share distributed among the top few providers, the large industry players took cognizance of the importance and the role that these online backup providers were playing in the web services arena and M&A activity has become quite predominant in the last few years. Today, most service providers of online backup services position their services using the SaaS (software as a service) strategy and its relevance is predicted to increase exponentially in the years to come as personal and enterprise data storage needs rise. The last few years have also witnessed a healthy rise in the number of online backup providers with them existing independently as also as part of a business unit of a larger industry behemoth.
Typical features
- Opened File Backup: The ability to back up files that are frequently left open, such as Outlook files (*.pst) or SQL database files. This feature allows IT administrators to run back-up jobs at any time of the day, not requiring server down-time. Most enterprise online backup products support an add-on for this. Higher-end products may support this natively.
- Multi-platform: A multi-platform back-up service can back up multiple platforms such as the various flavors of Windows, Macintosh, and Linux/UNIX.
- Multi-site: Some services offer the capability to back up both data at the primary site and data located at remote offices and branch offices, in a relatively seamless manner.
- Continuous backup - Continuous Data Protection CDP: Allows the tool to back up continuously or on a predefined schedule. Both methods have advantages and disadvantages. Most backup tools are schedule-based and perform backups at a predetermined time. Some services provide continuous data backups which are used by large financial institutions and large online retailers. However, there is typically a tradeoff with performance and system resources.
- Online Access to files: Some services allow you to access your backed up files via a normal web browser. Many tools do not provide this type of functionality.
- Data Compression: Data will typically be compressed with a lossless compression algorithm to minimize the amount of bandwidth used.
- Differential Data Compression: A way to further minimize network traffic is to transfer only the binary data that has changed from one day to the next, similar to the open source file transfer tool Rsync. More advanced network backup tools use this method rather than transfer entire files.
- Transfer Encryption: Encryption to prevent interception of data. This does not mean that the data will necessarily be encrypted during storage.
- End to End Encryption: Encryption of data at the client. The encrypted data is then transmitted and stored on the server. This requires a client generated key, and precludes data recovery should the key be lost. It also precludes certain optimization techniques (such as recognition of common operating system files which don't need to be stored multiple times, and removal of duplicate user files - 'de-duplication').
- Bandwidth Usage: User-selectable option to use more or less bandwidth; this may be able to be be set to change at various times of day
