Abstract
A system, method and computer program product for backup and restore of MS Exchange server. The method for MS Exchange Server backup and restore comprises launching a system filter and applying logs; mounting a data base from files located in a virtual folder; moving the file data from the archive into the real folder while the MS Exchange Server remains open and the database being restored is mounted. The data is moved into the real folder from the archive by blocks. The database files of the MS Exchange Server are divided into data sets (i.e., blocks). For each block a special bit in its bitmap is marked to indicate, whether this block has been moved to the real folder or still remains in the archive (i.e., backup). When the blocks are moved, the updated blocks do not need to be transferred from the archive into the real folder. After the data blocks are moved into the real folder, the restored database is dismounted and the virtual folder is dismounted. The system filter is turned off and the database is mounted without employing the system filter.
