Data recovery
Data recovery is the process of restoring data that has been lost, accidentally deleted, corrupted or made inaccessible. In enterprise IT, data recovery typically refers to the restoration of data to a desktop, laptop, server or external storage system from a backup.
Logical data recovery
The logical case is simpler and deals with a fully working hard drive, where data was lost due to accidental user actions, a crash by an application or the OS, or even partitioning/formatting of the hard drive by mistake.
Physical Data Recovery
The extraction of the raw data from a damaged disc. If a hard drive is not accessible by software such as the system BIOS, Windows' Disk Management, or other disk utilities it can be considered as truly dead and in need of physical data recovery.
Instant Data Recovery
Instant recovery makes backups directly accessible for quick restoration of files but also enables checking whether the backup system itself is actually working.
Continuous Data Protection
Continuous Data Protection (CDP), also called continuous backup, is a system that backs up data on a computer system every time a change is made. CDP maintains a continuous journal of data changes and makes it possible to restore a system to any previous point in time.
