A backup involves copying of data in order to restore it in the event that the original is lost. In simple cases, it is enough to copy individual files from their original location to other storage media. If there are ongoing personal computer backup solutions, it is necessary to block updates as long duplication is in progress. To limit the time when updates occur is done in two steps. First, copy the data to a fast medium such as a hard disk. Then copy data from this disk to the destination medium.
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.
The restoration of copied data is usually called restore. Operations involved in retrieving data are routinely subject to specific authorization from the Security Officer in case of failure or cancellation. The system administrator or users who have similar access rights ensure the restoration of required files.
Hot backups are performed while the program that uses the file to be copied is active. Data can then be modified while copying is in progress.Use of a disk image is a method of backing up an entire disk or file system into a single image. This method is useful to create exact copies of a disk, for example, perform an installation on many computers simultaneously.
Full backups entail backing up of all files on the system. Unlike the disk image, a full copy does not include the allocation tables, partitions and boot sectors. Differential backups involve copying of all changes made since the last full copy. The advantage is the reduced time compared to a full and incremental copy. The disadvantage is that the data to be saved for each day increases since the last copy.
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.
Portable hard drives with external connection USB and USB flash drives (usb-stick) have taken the place of floppy disks that are no longer in use due to poor reliability and limited capacity. You can also back up continuously using services such as online backup or the backup appliance which are instruments that allow this type of operation through agents.
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.
