Hybrid Online Backup works by storing data to local disk so that the backup can be captured at high speed, and then either the backup software or a D2D2C (Disk to Disk to Cloud) appliance encrypts and transmits data to a service provider. Recent backups are retained locally, to speed data recovery operations.
Traditional backups only restore data from the time the backup was made. True continuous data protection, in contrast to "snapshots", has no backup schedules. [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]
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.
Backup validation is the process whereby owners of computer data may examine how their data was backed up in order to understand what their risk of data loss might be. It also speaks to optimization of such processes, charging for them as well as estimating future requirements, sometimes called capacity planning.
Data portability requires common technical standards to facilitate the transfer from one data controller to another, such as the ability to export user data into a user-accessible local file, thus promoting interoperability, as well as facilitate searchability with sophisticated tools such as grep. [1] [2] Data portability applies to personal data.
A backup service supporting network backup can back up multiple computers, servers or Network Attached Storage appliances on a local area network from a single computer or device. Continuous backup – Continuous Data Protection Allows the service to back up continuously or on a predefined schedule. Both methods have advantages and disadvantages.
The backup data needs to be stored, requiring a backup rotation scheme, [4] which is a system of backing up data to computer media that limits the number of backups of different dates retained separately, by appropriate re-use of the data storage media by overwriting of backups no longer needed. The scheme determines how and when each piece of ...
the ability to back up a file while it is in use by another application. See File locking. Remote store. backing up data to an offsite permanent backup facility, either directly from the live data source or else from an intermediate near store device. Restore time. the amount of time required to bring a desired data set back from the backup media.
