Abstract: 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.

Abstract: Various embodiments are directed to systems and methods for creating an archive of a set of logical storage units stored on at least one storage medium.

Abstract: A process of writing to a non-anonymous cloud storage is provided. On a client side, a write request to block X is received. A block key for the block numbers X is calculates as a function, which uses an Anonymous Key and X as its arguments. A hash function value of the block key is calculated. The content and the hash value are transferred to a Virtual Cloud Service. Then, on the Virtual Cloud Service, public cloud accounts are selected based on part of the hash value. A file name is generated from the calculated hash value. The content of block X is stored to the file with the generated name within the selected cloud account. Thus, there is no data reflecting the ownership of the user files on the cloud storage that is revealed.

Upon receiving the first lock request, the tracking utility may copy the current changes list to a frozen changes list and clear the current changes list. Upon receiving a second lock request, the tracking utility may merge the current changes list and the frozen changes list.
