A system, method and computer program product for restoration of MICROSOFT Exchange Server mail. MICROSOFT Exchange Server mail is retrieved from a virtual copy of the MICROSOFT Exchange database. Virtualization is implemented by a system filter. Logs are applied to a virtualized DB in order to synchronize it with a real DB of the MICROSOFT Exchange. The data located in the remote archive does not need to be copied into the real folder, because the data is made available by virtualization means. After the logs are applied, the virtualized DB is opened (without being mounted) from files from the virtual folder. From this point on, the DB of MICROSOFT Exchange can be viewed and the data can be queried and retrieved from the virtualized DB. Thus, a single message or a mailbox can be retrieved very fast, as if it were being retrieved from a real MICROSOFT Exchange DB.

System and method for restoration of MS exchange server mail

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.

System and method for online backup and restore of MS exchange server

A method for managing archived data includes creating a plurality of images of storage devices of computing systems and for, different users, each image being associated with a restore point of a particular storage device; storing the images for the different users in different storage locations, the storage locations being controlled by a single backup server and belonging to storage pools. Multiple locations of one user are stored in different pools on different storage devices. The method also involves moving contents of locations of one user from one pool to another in predefined direction, simultaneously with reorganizing images within the locations. Each image is a backup of one user's data. At least some of one location's content is frozen so that it is never moved from one pool to another. The storage devices of locations of different pools differ from each other by type, such that storage devices in a first pool are hard disk drives, storage devices in the next pool are SAN, or an NAS, and a storage device in the next pool is a network disk drive accessible through a network and a storage device in the next pool is a magnetic tape drive.
