Backup software is software designed to backup data for the purpose of having a second copy of an original source in case of damage to the original data source. Software redirects here. ... For other uses of Backup, see Backup (disambiguation). ...

Key features of backup software

There are several features of backup software that make it more effective in backing up data.

Volumes

Main article: Volume (compression)

Voluming allows the ability to compress and split backup data into separate parts for storage on smaller, removable media such as CDs. It was often used because CDs were easy to transport off-site and inexpensive compared to hard drives or servers. A volume is a term in data compression for a file who has been compressed and split into different parts. ... A volume is a term in data compression for a file who has been compressed and split into different parts. ... Removable media are transportable drives or disks that can be moved easily from one computer to another. ... CD may stand for: Compact Disc Canadian Forces Decoration Cash Dispenser (at least used in Japan) CD LPMud Driver Centrum-Demokraterne (Centre Democrats of Denmark) Certificate of Deposit České Dráhy (Czech Railways) Chad (NATO country code) Chalmers Datorförening (computer club of the Chalmers University of Technology) a 1960s... Typical hard drives of the mid-1990s. ... In information technology, a server is an application or device that performs services for connected clients as part of a client-server architecture. ...

However, the recent increase in hard drive capacity and decrease in drive cost has made voluming a far less popular solution. The introduction of small, portable, durable USB drives, and the increase in broadband capacity has provided easier and more secure methods of transporting backup data off-site. A 3. ... Broadband in telecommunications is a term that refers to a signaling method that includes or handles a relatively wide range of frequencies, which may be divided into channels or frequency bins. ...

Data compression

Since hard drive space has cost, compressing the data will reduce the size allowing for less drive space to be used to save money. Source coding redirects here. ... Typical hard drives of the mid-1990s. ... Source coding redirects here. ...

Remote backup

Main article: Remote backup

Several factors have contributed to a surge in the use of remote or offsite backup of data to geographically distant sites. This article needs to be cleaned up to conform to a higher standard of quality. ...

1. The rapid growth of data and its importance to business.
2. The rapid adoption of high-speed broadband internet.
3. The falling price of disk drive technology.
4. The rise of risks such as hackers, hurricanes, viruses, hardware failure.

These structural changes present opportunities for young startups, which are serving this growing market with next-generation backup technologies that automatically backup data to offsite data centers (sometimes called vaults) via the Internet. Many banks, stock exchanges, and other large institutions often do this to ensure data integrity. For other uses, see Bank (disambiguation). ...

Access to open files

Main article: File locking

Many backup solutions offer a plug-in for access to exclusive, in use, and locked files. File locking is a mechanism that enforces access to a computer file by only one user or process at any specific time. ...

Incremental backups

Main article: Backup rotation scheme

Backup solutions generally support incremental backups in addition to full backups, so only material that is newer or changed compared to the backed up data is actually backed up, in order to dramatically increase the speed of the backup process. A Backup rotation scheme is a method for effectively backing up data where multiple media (such as tapes) are used in the backup process. ...

Schedules

Main article: Job scheduler

Backup schedules are usually supported to reduce maintenance of the backup tool and increase the reliability of the backups. // A job scheduler is a enterprise software application that is in charge of unattended background executions, commonly known for historical reasons as batch processing. ...

Encryption

Main article: Encryption

To prevent data theft some backup software offers cryptography features to protect the backup. Encrypt redirects here. ... Data theft is a growing problem primarily perpetrated by office workers with access to technology such as desktop computers and hand-held devices, since employees often spend a considerable amount of time developing contacts and confidential and copyrighted information for the company they work for they often feel they have...
