[ 5 ] When data is written to disk, it is also asynchronously written to a second location, either another computer over the network [ 6 ] or an appliance. [ 7 ]

Site-to-site backup. backup, over the internet, to an offsite location under the user's control. Similar to remote backup except that the owner of the data maintains control of the storage location. Synthetic backup. a restorable backup image that is synthesized on the backup server from a previous full backup and all the incremental backups ...
This is a list of notable backup software that performs data backups. Archivers, transfer protocols, and version control systems are often used for backups but only software focused on backup is listed here. See Comparison of backup software for features.
Another kind of database software exists to manage the provisioning of new databases and the management of existing databases and their related resources. The process of creating a new database can consist of hundreds or thousands of unique steps from satisfying prerequisites to configuring backups where each step must be successful before the ...
