Many network administrators, while designing the network, only consider data backup, but do not consider data restoration which is an equally important process. In the literature, some authors have even emphasized the importance of restoration of data more than the back up by mentioning that the backup can only be as good as the ability to restore and problems occur if the system designers do not put in sufficient consideration in the architecture of for data restoration as well as for backup.

There are a number of issues which should be considered in the restoration of data. These issues must be dealt with in order for the restoration process to be easy and swift. First of all, the network administrator needs to constantly monitor the data integrity of the backup before a restoration is needed. To accomplish this, the network administrator has to constantly test for proper integrity of the back using the catalog software to make sure all the files are accounted for. Furthermore, restoration of an archive also relies on how comprehensive a catalog is. Therefore, for a comprehensive restoration the catalog of the archive should also be ensured by the network administrator (Krogh, 2010).

From the network point of view as well, there are several issues that need consideration. One important issue that should be looked at by the network administrator is that cause of corruption of data which caused for data restoration. Data can get corrupted in a number of ways. For example, a user can delete a database of file by mistake or it can also be caused by a problem in database software, the file system, by the device driver or a firmware problem. Hence, it is important to take care of these issues first in order to ensure that the process of data restoration does not take place on constant basis. Furthermore, it is also critical to consider the architecture of the network as well as the backup policy to ensure that the data restoration process does not become cumbersome. For example, in a large environment where all the backups are done on a single backup server connected to the same network as the user computers, a restoration procedure could lead to a network bottleneck causing severe degradation in restoration speed and would significantly extend the restoration procedure.  Several strategies can be employed in order to prevent such degradation from happening. For example, the network administrator should enforce different levels of storage performance. Furthermore, different media can be used to enforce various types of restoration of data. For example, to restore the data for a particular user, CDs and DVDs can be used, however, to restore large amount of data such during disaster recovery, backup tapes can be used. Furthermore, users should also be encouraged to back-up their data on their own computer, so that and accidental deletion of a file does not require from a network administrator to go through the whole back up catalog to look for the file. In addition, the network architecture should also support the quick restoration of data.  This could be provisioned by ensuring different network topology for different users which would restrict the exchange of data to only few segments and hence would enable the network to support full rate data restoration and functionality (Newman, 2006).
