The operation of restoring the backup data of the US website server is not very simple. It requires a suitable solution to perform the operation. In order to basically achieve the goals of the US website server users, this article will introduce some solutions for restoring the backup data of the US website server. .

　　1. File-level restoration

　　File-level restore is one of the earliest methods of backing up data on U.S. website servers, and it is still widely used. Through this method of operation, U.S. website server users can directly restore individual files in the backup data back to the U.S. website server. These restores are performed through an agent on the source side, but most are now agentless and perform image-level backups at the hypervisor layer, so they perform file-level restores slightly differently than traditional methods.

　　The current operation method is to first access the file from the backed-up mounted virtual disk or .vmdk, rather than accessing it from the backup storage. When performing this mount, the virtual disk containing the target files is mounted read-only so that the integrity of the backup virtual machine used for subsequent backup jobs of the US website server is not affected. This enables the backup server to access the required files, perform a copy operation, and transfer the files back to their original location or to connect to the backup server's local disk. Once the operation is complete, the virtual disk can be unmounted and reattached to the backup copy of the virtual machine directly in a compressed and deduplicated format.

　　2. Virtual machine file/disk level restore

　　In VMware, the US website server virtual machine is packaged into a group file, with a .vmx file, one or more .vmdk files, and various other files. Backup solutions such as Veeam Backup & Replication process these files during the backup process and provide corresponding restore methods.

　　The most important practical effect of virtual machine file-level restore is the ability to restore a single .vmdk file, which allows US website server users to restore the entire virtual machine disk one by one. This is useful for cases where the data disk is damaged but the operating system disk is still running normally. Situations can be very useful. US Web Server users will be able to restore just one data disk, rather than choosing to restore an entire virtual machine or handle multiple file-level restores.

　　3. Image level/virtual machine restoration

　　Sometimes file-level restore of U.S. website server backup data is not enough to restore the virtual machine, so image-level/virtual machine-level restore needs to be performed. Virtual Machine Level Restore Leveraging virtualization, backup servers are able to perform point-in-time backups of entire virtual machines and restore them to their original location or to a different location. In this way, US website server users can flexibly restore to different storage arrays or different US website servers.

　　4. Quick rollback

　　With a quick rollback solution, the US website server data can be queried from the current VMware CBT file and compared to the backed up CBT file, noting which data blocks must be transferred back to the original virtual machine for recovery to the specified correct time point. The data protection solution then only needs to migrate or restore different data blocks between the source and destination. This significantly reduces the time required to restore virtual machines and reduces the impact on production storage performance.
