    摘要: A method includes identifying a first boot configuration type for a disk image. The disk image includes a master boot record and a disk partition. The disk partition comprises a volume boot record. The master boot record comprises first instructions for loading an operating system, and the volume boot record comprises second instructions for loading the operating system. The method further includes receiving an input indicative of a second boot configuration type. The method also includes modifying the disk image to use the second boot configuration type to load the operating system by modifying the first instructions and the second instructions.

    摘要: Systems and methods for generating a bookmark for a snapshot of one or more volumes of a production server include initiating a snapshot process to capture a shadow copy of a snapshot-volume set, which includes one or more volumes of the production server. The snapshot process (e.g., Volume Shadow Copy Service of Windows™ operating system) may include (a) temporarily freezing operations on a file system of the production server, and (b) releasing a freeze of operations on the file system of the production server. A bookmark for the shadow copy (representing a consistent state of the associated volumes) may be generated such that the bookmark corresponds to a completion of the temporarily freezing or releasing a freeze of the operations. The bookmark may include a point in time of the completion of the temporarily freezing or releasing the freeze of the operations.

    摘要: Systems and methods for replicating data from a production server to a backup server include recording at least one operation on one or more data items stored in a volume of a production server. The operation may be recorded as at least one journal event in a memory. A determination may then be made regarding whether a system malfunction incident has occurred in the production server and if so, a first set of journal events may be transferred from the memory to an auxiliary storage at a first time instant. At a second time instant, a second set of journal events recorded in the memory between the first and second time instants may be transferred to the auxiliary storage. At one journal event stored in the auxiliary storage unit may then be sent for replication to a backup server.

    摘要: Systems and methods for replicating data from a production server to a backup server include identifying one or more data blocks of a file that were modified after a first time instant and before a second time instant. The file may be associated with a protected directory of the production server. An representative data block (e.g., including a hash value) for at least one of the identified data blocks may be computed using a cryptography algorithm, e.g., MD5 or SHA-1. The computed cryptographic data block representing the identified data block may then be sent for replication to the backup server. An operation performed between the first time instant and the second time instant on one or more files of the protected directory may be recorded, and sent to the backup server.
