A method for data synchronization is provided. Custom Objects are stored in MICROSOFT Outlook as Outlook items. Two continual processes check if there are changes in the Outlook Items and whether these changes are saved on the hard drive. MICROSOFT Storage Items are used to store information about fields of Outlook items that have been changed and fields of Outlook items that have been saved to the hard drive. Then, information about both changed and saved fields is sent to an external server. Subsequently, notifications about successful saving of the fields on the external server are received. The information about the fields changed on the external server is received, as well. The fields changed on the external server are saved to the Outlook items. Thus, two-way synchronization between Outlook and the external server is achieved.

A system, method and computer program product for booting a computer system from the backup and working with the backup as if it were a normal storage device, including loading an initialization application to run in a single thread mode and that identifies a storage media with the backup that includes boot blocks; installing and activating a handler of a Basic Input/Output System (BIOS) interrupt module, for intercepting boot loader requests to the storage media, and for redirecting them to the backup; creating a bitmap of the data blocks stored in the backup and of a writable data storage device to which new data will be written; initiating the BIOS to load and execute the boot blocks from the backup; transferring control to a routine defined by a boot record stored in the backup's boot blocks; installing and activating an I/O filter for intercepting the requests to the writable data storage device, and after a write request is received, the I/O filter writes a corresponding data block to the writable data storage, and marks this data block in the bitmap to indicate that this block is stored on the writable storage device; after a read request is received, the I/O filter checks the bitmap to see if this data block was not changed, and redirects the read request to the backup to read the data block, and if the requested data block was changed and written to the writeable data storage device, then the I/O filter redirects the read request to the written blocks on the writeable data storage device.

System and method for booting a computer from backup

Continuous data protection is performed as two parallel processes: copying a data block from the storage device into the backup storage device (creating initial backup) and copying the data block to be written to the data storage into the incremental backup. When a write command is directed to a data storage block, it's intercepted and redirected to the backup storage, and data, which is to be written in accord to the write request, is written to the incremental backup on the backup storage. If write command is also directed to a data storage block identified for backup that has not yet been backed up, the identified data storage block is copied from the storage device to the intermediate storage device, the write command is executed on the identified data storage block from the storage device, and the data storage block is copied from the intermediate storage device to the backup storage device. In case of an error accessing a block on the storage device, the block is marked as invalid. The system suspends a write command to the storage device during the initial data backup process if the intermediate storage device has reached a selected data capacity; and copies a selected amount of data from the intermediate storage device to the backup storage device.

Method and system for continuous data protection

Method for booting from a backup, including loading an initialization application that identifies a storage with a backup; activating a handler of a BIOS interrupt module, for intercepting boot loader requests to the storage, and for redirecting them to the backup; creating a bitmap of the blocks in the backup and of a writable storage device to which new data will be written; initiating the BIOS to load and execute boot blocks from the backup; transferring control to a routine defined by a boot record in the boot blocks; activating an I/O filter for intercepting requests to the writable storage device; for write requests, the filter writes a corresponding block to the writable data storage, and marks this block in the bitmap; for read requests, the filter checks the bitmap if this data block was unchanged, and redirects the read request to the backup, otherwise, the filter redirects the read request to the writeable storage device.

A method of and system for protecting a disk drive or other data storage includes mounting a virtual storage that combines a READ-only portion of a volume of the main storage and a full access temporary storage located on the same data storage, wherein the READ-only portion represents a protected area of the volume of the main storage; generating a bitmap for blocks of the virtual storage; redirecting virtual storage write requests to the temporary storage; marking, in the bitmap, blocks of the virtual storage corresponding to blocks of the temporary storage that are being written to; redirecting, to the READ-only portion, read requests for unmarked blocks; redirecting, to the temporary storage, read requests for marked blocks; upon an acceptance of a state of the virtual storage, merging the temporary storage with unmarked blocks of the READ-only portion of the volume of the main storage, to form an integral storage; and upon a rejection of a state of the virtual storage, terminating the redirecting. Optionally, data in the temporary storage can be archived.
