The definition of a Data Recovery Services backup (English: backup) describes the copying of data with the intention of copying them back to the main system in the event of data loss. A Data Recovery backup is therefore considered one of the most important measures for data security and includes all possibilities that can protect data from manipulation, damage and loss.
If the data is stored redundantly on a separate storage medium, there is a backup. Restoring the original data from a backup copy is data recovery, not data rescue .
Data loss due to defective data backup :
The creation of a backup is commendable and generally mandatory for companies. In our personal experience, however, there is much more to it than just backing up Facebook data from A to B on a weekly or daily basis. It is not uncommon for the functionality and integrity of the backed-up databases to be completely neglected. In an emergency, this can lead to faulty data stocks being uploaded in the event of data loss and subsequent restoration of the data.
Scenarios such as a corrupt database backup or faulty snapshots are not uncommon and are part of everyday data recovery. But data loss does not always have to be of such magnitude. Apple’s Time Machine Backup or Acronis backups can also backup data incorrectly without being noticed. In most cases it is not noticed, because the automatisms are intended to reduce the manual effort and to minimize the necessary controls by humans.
However, the announced effort minimization usually develops into a risky convenience and one increasingly relies on the algorithms. So it can happen that data is transferred and backed up over weeks or months, which the user can see, but is there also a qualitative evaluation of the process? Is the emergency rehearsed with a failure of the original system? Can the secured data backups be transferred back without any problems? As part of the disaster recovery plan, it is necessary to preventively play through the occurrence of an emergency and to take the associated eventualities into account.
However, if you rely too much on the automatic data backup mechanisms that work in the background and fail to manually check that the data backup is correct, you run the risk of suffering a permanent loss of data. There are certainly chances and possibilities to get the main or source system running again and possibly get away with it with a dread. But in view of the supposed data backup in the back hand, all possible measures are taken in such cases and work is risky – since it is assumed that the network and double bottom are used safely. So it can happen that afterwards not even a data rescue can be possible, since the attempts to iron out the errors have caused even more damage.
