Each node within a hyper-converged system contains its own integrated storage, compute and network resources. One of the main benefits of hyper-converged systems is that they are easily scalable. These systems consist of collections of standardized servers that have been clustered together and collectively handle backup-related processes. Some backup vendors have also begun offering backup platforms that are based around the use of hyper-converged systems. These plug-and-play data storage devices often include automated features for monitoring disk capacity, expandable storage and preconfigured tape libraries. At its simplest, an integrated data appliance is essentially a file server outfitted with HDDs and backup software. These systems gained rapid popularity because they acted as online backups, meaning data could be backed up or restored on demand, without having to mount a tape.Īlthough some backup products still use separate backup servers, backup vendors are increasingly transitioning to integrated data protection appliances.

This software coordinated the backup process and wrote backup data to a storage array. In the early days of disk backup, the backup software was designed to run on a separate server. These types of backups can protect both structured data - data stored on a database server - and unstructured or file data.

The systems perform an initial full backup to disk, and then perform incremental backups every few minutes as data is created or modified. This forced many organizations to create nightly incremental backups.Ĭontinuous data protection platforms avoid these challenges completely.

As time went on, the backup files became larger, while the backup windows remained the same size or even shrank. Early on, the nightly backups were all full system backups. Prior to disk-based backups, organizations would typically create a single nightly backup. Some organizations have adopted the practice of using a removable external drive instead of a tape, but the basic concept of backing up data to removable media remains the same.ĭisk-based backups made it possible for organizations to achieve continuous data protection. Tape is still used today, but mainly for archived data that does not need to be quickly restored. Backup software also enforces policies that govern how often specific data is backed up, how many copies are made and where backups are stored.īefore disk became the main backup medium in the early 2000s, most organizations used magnetic tape drive libraries to store data center backups.

Backup software handles processes such as data deduplication that reduce the amount of physical space required to store data. Backup software - either integrated in the appliances or running on a separate server - manages the process of copying data to the disk appliances. The evolution of backup storage mediaĮnterprises typically back up key data to dedicated backup disk appliances.

To supplement weekly full backups, enterprises typically schedule a series of differential or incremental data backup jobs that back up only the 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 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 snapshot that 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. The process of backing up data is pivotal to a successful disaster recovery plan.Įnterprises 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. James Alan Miller, Senior Executive Editorīackup refers to the copying of physical or virtual files or databases to a secondary location for preservation in case of equipment failure or catastrophe.
