Data Recovery Services software needs storage media to set up your Mac backups . Several means are possible: internal or external hard drive , NAS , RAID or even a partition dedicated to recovery.
It is recommended to use a medium of at least 1TB , more if the user produces a lot of Data Recovery Services especially in audiovisual production. The implementation of the backup is simple and its action must be planned on a regular basis.
Thus, in the event of data loss, the solution will be able to establish precise monitoring of file modifications, thus facilitating their protection. Depending on the software, several types of backups are available: there are no better ones, only the operation is different.
Regardless of the Data Recovery Services application, the principle is the same: it will first analyze the disk allocation table to establish a map on the distribution of files. The index being created, any modification, deletion and addition of file is recorded in this mapping allowing the solution to know the location of the files on the support.
Therefore, when the Data Recovery Services is launched, each file is put back in its place during the last analysis. For optimal efficiency in data protection, it is useful and simple to set up a complementarity with a secure online space ( cloud ). Security is thus reinforced and the user can retrieve and use his data quickly. When a file is written to disk, the zone or cluster is then busy.
This space is free when the file is deleted. In the event of accidental deletion of a file, do not rewrite new files at the risk of leaving no more room available for recovery.
