![]() These plug-and-play data storage devices often include automated features for monitoring disk capacity, expandable storage and preconfigured tape libraries. An integrated data appliance is essentially a file server outfitted with HDDs and vendor-developed backup software. Both disk and tape are still used today, and often in conjunction.Īs file sizes have increased, some backup vendors have brought integrated data protection appliances to market in an effort to simplify the backup process. Data deduplication systems contain hard disk drives ( HDDs) and are equipped with software for setting backup policies.ĭisk-to-disk backup systems initially appeared as an alternative to magnetic backup tape drive libraries. Backup storage mediaĮnterprises typically back up key data to dedicated backup appliances or magnetic tapesystems. To supplement weekly full backups, enterprises typically schedule a series of differential or incremental data backup jobs that back up only data that has changed since the last full backup took place. The process is governed by predefined backup policies that specify how frequently the data is backed up and how many duplicate copies (known as replicas) are required, as well as by service-level agreements ( SLAs) that stipulate how quickly data must be restored.īest practices suggest a full data backup should be scheduled to occur at least once a week, often during weekends or off-business hours. What data should be backed up and how frequently?Ī backup process is applied to critical databases or related line-of-business applications. The terms data backup and data protection are often used interchangeably, although data protection encompasses the broader goals of business continuity, data security, information lifecycle management, and the prevention of malware and computer viruses. The process of retrieving backed-up data files is known as file restoration. ![]() The goal is to ensure rapid and reliable data retrieval should the need arise. Backups capture and synchronize a point-in-time snapshotthat is then used to return data to its previous state.īackup and recovery testing examines an organization’s practices and technologies for data security and data replication. ![]() Enterprises back up data they deem to be vulnerable in the event of buggy software, data corruption, hardware failure, malicious hacking, user error or other unforeseen events. ![]()
