What is 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 restoring data to a desktop, laptop, server, or external storage system from a backup.
How successful is data recovery?
In about 75-80% of cases at least 75% of the files can be recovered. If there is an NTFS volume involved, averages are a bit worse: 40% chance for a successful recovery (at least 90% of files) and about 75% chance to recover at least 70% of the files.
How does data recovery work?
In the case of accidental data deletion, data recovery software uses deterministic and heuristic algorithms to find the location of deleted files, and then attempts to recover as much of the data as possible. However, the chances of successful data recovery depend largely on the file system of the device in question.
How long does data recovery take?
Generally, data recovery will take 2-5 days. However, the time it takes to recover data will vary depending on the problem. After a technician takes a look and diagnoses the problem you will get a better estimate of the time it will take to recover your data.
Do data recovery companies look at your files?
If you’re talking about a data recovery service, they’re necessarily going to at least see the *names* of the files. They’re trying to recover the files after all. As for opening the files, while they’re technically not supposed to be opening files that have nothing to do with the repair…well…things happen.
