A method, computer program product, computing system, and system for automated disaster recovery are described. The method may include creating, using a backup engine running at a computing device, a backup of a server at a primary computing site; storing the created backup at a storage device at a secondary computing site; monitoring, using a monitoring component, an operating status of the server at the primary computing site; in response to determining, via the monitoring component, that the server at the primary computing site is unavailable based on the operating status, initiating a disaster recovery process at the secondary computing site; and running a copy of the server from the created backup at the secondary computing site.

Automated disaster recovery and data redundancy management systems and methods

Systems and methods for migrating and/or replicating computer systems are disclosed. Computer systems may be migrated and/or replicated from physical systems or virtual systems to physical or virtual systems. Migrating/replicating computer systems comprises determining the structure of the source computer system, generating instructions for migrating/replicating the structure of the computer system, and packaging the instructions in an executable package. The instructions may be formatted as a template, such as an OVF template, and be packaged with an executable agent and task list. The executable agent may be received and executed by a destination computer system. Executing the executable package may cause the instructions to be executed, as well as the optional agent, there configuring the destination computer system, possibly copying data present on the source computer system, and possibly rebooting the destination computer system.

System and method for platform-independent migration and replication of computer systems

The subject matter of this specification can be implemented in, among other things, a method that includes receiving, from within a guest operating system hosted by a host operating system at a computer system, requests to access sparse files within a guest file system of the guest operating system. The sparse files each correspond to an external data file outside the guest file system. Each of the requests to access the sparse files within the guest file system is directed to the corresponding external data file outside the guest file system. The method includes identifying a frequency with which each of the sparse files is accessed. The method includes moving an external data file from a first type of storage device to a second type of storage device based on the frequency with which the external data file is accessed relative to others of the external data files.

Access frequency-based file management in virtualized computing environments using sparse files

The subject matter of this specification can be implemented in, among other things, a method that includes receiving, from within a guest operating system, a request to create a data file in a guest file system of the guest operating system. The method further includes in response to the receipt of the request to create the data file, creating an external data file in a first storage device for a file system outside the guest file system, creating a sparse file in the guest file system, and storing metadata that directs requests to access the sparse file from within the guest operating system to the external data file in the first storage device.

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.
