Data recovery is the process of restoring lost, accidentally deleted, damaged, or inaccessible data. It is necessary due to physical damage to the storage devices or logical damage to the file system that prevents the host operating system (OS) from mounting it. Logical errors occur when the hard drive works, but the user or the automated OS cannot retrieve or access the date stored on them. Data recovery encompasses a set of methods used to recover lost data or information. Some companies don't implement a disaster recovery solution due to cost issues.
However, they must ensure that they at least have an appropriate data recovery solution in place. Data recovery is part of disaster recovery, but should not be confused with an alternative to disaster recovery. Various physical devices are used for data storage, such as hard drives, CD and DVD ROMs, solid-state drives, flash drives, and RAID systems. Hardware interruptions are actually the leading cause of data loss incidents, as cited by 47% of recent respondents.

can also be used to recover files that were not backed up and that were accidentally deleted from a computer's file system, but that still remain on the hard drive in fragments.It requires determination, experience, appropriate recovery tools, class 100 clean rooms, a biometric environment and, of course, a data recovery technician who can perform data recovery. The downside of this approach is the expense and downtime without the hard drive. But if the data is valuable enough, it may be the only difficult option on its own. If you take your drive to a data recovery specialist, they will take a number of steps, from reconstructing parts of the hard drive to creating a disk image and doing everything possible to repair the damaged parts with sophisticated software. Don't forget that data recovery specialists can charge up to three hundred or four hundred dollars per hour for their highly specialized services. We also need to consider modern storage solutions such as cloud storage and data stored on mobile phones and tablets which are capable of storing data on their removable memory cards.
SSDs handle deleted data and data recovery differently than hard drives do. There are numerous free data recovery programs that can help you recover lost data but while these programs can be useful it's imperative that you do your homework. A snapshot is created so that the backup remains in an impeccable state and all user writing operations are redirected to that snapshot; then users work from the backup virtual machine (VM) and the recovery process begins in the background. It's free because companies want you to try the possibilities of recovering your data and then just buy the software. Data recovery is possible because a file and the information about that file are stored in different places. The most important thing to remember when it comes to data recovery is to remove all energy from the drive experiencing data loss as soon as possible.
