Patent number: 11762740Abstract: Disclosed are systems and methods restoring a computing system. The described method includes emulating a virtual disk using a backup of the computing device and generating an ancillary virtual machine (VM). The method includes determining and writing, to a delta disk linked to the virtual disk, configuration modifications to the ancillary VM that enable booting of the ancillary VM using the virtual disk on a different device with dissimilar hardware as the computing device. Responsive to receiving a request to perform recovery of the computing device, the method comprises restoring the backup by creating on the different device a recovery virtual machine (VM) having a base virtual disk emulated from the backup, and modifying the recovery VM by attaching the delta disk having the configuration modifications.Type: GrantFiled: March 24, 2021Date of Patent: September 19, 2023Assignee: Acronis International GmbHInventors: Vadim Karasev, Vasily Semyonov, Stanislav Protasov, Oleg Shaikhatarov, Serguei Beloussov

Patent number: 10990485Abstract: Disclosed are systems and methods restoring a computing system. The described method includes receiving a delta disk that was generated based on a backup of a computing device executing a protected application. The delta disk comprises one or more configurations for executing the protected application on a different device than the computing device. In response to a request to perform recovery of the computing device, a recovery virtual machine (VM) is created having a base virtual disk emulated from the backup. The recovery VM is modified by attaching the delta disk having the one or more configurations for executing the protected application. Execution of the protected application on the recovery VM is resumed.Type: GrantFiled: February 9, 2018Date of Patent: April 27, 2021Assignee: Acronis International GmbHInventors: Vadim Karasev, Vasily Semyonov, Stanislav Protasov, Oleg Shaikhatarov, Serguei Beloussov

Patent number: 10678651Abstract: A method, computer program product, computing system, and system for backing up a virtual machine using a snapshot with memory are described. The method may include receiving a selection of a virtual machine to be backed up, wherein the virtual machine reads from a source virtual disk. The method may further include creating a non-quiesced snapshot with memory of the virtual machine that captures a state of the virtual machine. The method may also include creating a linked clone of the virtual machine and reverting the linked clone back to the state of the virtual machine using the non-quiesced snapshot with memory. Additionally, the method may include gracefully shutting down the linked clone of the virtual machine such that the linked clone is in a consistent state. Moreover, the method may include reading data from one or more virtual disks associated with the linked clone and saving the data.Type: GrantFiled: December 10, 2015Date of Patent: June 9, 2020Assignee: ACRONIS INTERNATIONAL GMBHInventors: Alexey Borodin, Vasily Semyonov, Stanislav Protasov, Serguei M.

Patent number: 10514989Abstract: A method, computer program product, computing system, and system for recovering a virtual machine while running the virtual machine from a backup archive are described. The method may include emulating the virtual machine in preparation for finalizing the recovery of the virtual machine. The method may include creating a snapshot of the emulated virtual machine to redirect changes to the emulated virtual machine to a second delta file in the production datastore. The method may include cloning an original base virtual disk, including the first delta file, to the production datastore to create a cloned base virtual disk. The method may include patching a virtual disk file descriptor of the second delta file of the emulated virtual machine. The patching operation may include replacing links to the original base virtual disk of the emulated virtual machine, including the first delta file, with links to the cloned base virtual disk.Type: GrantFiled: September 8, 2016Date of Patent: December 24, 2019Assignee: ACRONIS INTERNATIONAL GMBHInventors: Alexey Borodin, Vasily Semyonov, Stanislav Protasov, Serguei M.

Patent number: 10481984Abstract: A method for minimizing VMWARE™ snapshot lifetime, by reading data from a storage snapshot created on the VM storage side. The reading is performed by mounting the storage snapshot as a new datastore on an ESX(I) host and accessing the host using a standard VMWARE™ VDDK (vStorage API) method. A pre-configured source ESX(I) host contains a VM that needs to be backed up. A SAN storage connected to the ESX(I) host over iSCSI or FibreChannel or NFS protocols is used. The backup agent, which contains the proprietary code, is installed on a physical or a virtual machine connected to an ESX(I) host. This backup agent maintains the operations with the ESX(I) host and the SAN storage and coordinates the VM virtual disks data read and write operations. The backup agent contains the executable code, which provides compatibility with SAN storage and ESX(I) host.Type: GrantFiled: November 23, 2015Date of Patent: November 19, 2019Assignee: ACRONIS INTERNATIONAL GMBHInventors: Vasily Semyonov, Stanislav S. Protassov, Serguei M. Beloussov, Mark Shmulevich, Victor Shulga

Patent number: 10296423Abstract: A system and method is disclosed for live virtual incremental restoring of data from a cloud storage. An example method includes, in response to detecting a data backup, collecting information by a hardware processor of a computing device for configuring a list of changed sectors (LCS) of a storage medium of the computing device as a result of the data backup. The method further includes virtually restoring at least a portion of electronic data saved in the storage medium of the computing device from the cloud storage, the selected electronic data being previously saved in the cloud storage. The method also includes rebooting the computing device and applying changes to the storage medium of the computing device based on the LCS during a subsequent data backup.Type: GrantFiled: March 31, 2016Date of Patent: May 21, 2019Assignee: Acronis International GmbHInventors: Victor Shulga, Vasily Semyonov, Serguei Beloussov, Stanislav Protasov, Mark Smulevich, Andrey Redko
