Deduplication is achieved through the use of algorithms (which means elimination of duplicates) that can act at the level of single files or block level, which is a set of files. Personal computer backup solutions can be performed before, during or after the copying or deferred in relation to the normal operation of information systems.
Deduplication is useful, in particular for groups of files or file folders that need a full duplicate. The storage of media in physically separate locations is necessary, so that in the event of theft, fire, flood or other catastrophic event, copies may not be lost along with the original.
Most current operating systems for personal computers integrate a duplication program, but only specially-equipped servers typically contain a native service. In companies, the type and its periodicity are usually regulated by a specific procedures subject to regular monitoring and other events that involve manual intervention. The safety officer is required to conduct regular checks and interventions on the systems.
The advantage of an online system is that an external supplier who can guarantee the storage while making the entire process easy to handle can handle the protection of data. Online service also come under different names such as remote storage and remote backup. There is the prevalence of fast Internet connections, which are settled with a fixed monthly payment, and the traffic is unlimited.
The main features that a back up program must provide include copying an image of a hard drive; selective copy of individual files and directories; selection criteria for the search of stored contents and the choice of those that must be covered (by date, file type, author of the amendment).
The incremental process includes all files added or changed since the last duplication (full, incremental). An incremental variant is less rapid than differential; may take a longer time because you need to restore from the last full copy and then add in sequence all the incremental backups. Remote backups perform data backups through the Internet to an appropriate server connected. In the majority of cases, an appropriate software is used.
Data recovery or salvage is an attempt to recover data needed when normal methods are impossible. For example, a hard-drive crash may still contain data. Specialists with special tools in controlled environments carry out the operation of data recovery: the damaged disk is opened in a room without dust. It is repaired as much as possible and most data is so often recovered. One of the main purposes of backups is to provide a basis for disaster recovery. To get a truly effective process you need to plan and carry out disaster recovery tests before the actual need arises.
Backup window is a period in which a system is available for copying. Related procedures can have an effect of slowing down the systems and network; some operations require that the primary use of system is suspended. These effects can be mitigated by agreeing on a reinforcement window. Backups policy is a set of rules in place to ensure that the process runs in a way that is appropriate to the needs of users or business organization. A policy defines the type (full or incremental), frequency (usually daily), and includes rules for checking compliance of restore process.
