Virtualization technology makes IT environment more flexible. The performance of servers can be utilized more effectively to let the hardware resource used by several VMs.
VM backup is an important part of disaster recovery. Backup can rewrite the problematic VM to fix any issues and prevent ransomware. It is useful to recover full VM but sometimes you don't need to fully rewrite the VM. When it is only certain files that are needed, file level restore might be the better solution.
File level restore lets you recover or extract certain files from the full VM backup. Usually, you can preview the files of the VM via certain tools and then select the needed files to use. It is also called granular restore in some software.
VMware once released a plugin as the internal vSphere backup solution, called VMware Data Recovery. One of its feature is File Level Restore, FLR. FLR lets you read the content of certain recovery point and copy the file from the entire VM backup. It is only allowed to copy files while you can't modify any files in the backup so that the backup won't be damaged.
Note: VMware Data Recovery is not available now. You can try a VMware Data Recovery alternative, Vinchin Backup & Recovery, which is the official partner of VMware. File level recovery is also supported in VMware vSphere environment.
Although full VM recovery is powerful and often the first choice for disaster recovery, file level recovery can a better in some scenarios.
Business systems are used by many users. No one can promise standard operation all the time. Incorrect operations might cause important files deleted but the whole system still can be used by most users. If so, file level recovery will the better choice.
Full VM recovery often takes a long time so you are in a dilemma that whether you should keep using the problematic system or take time to fully rewrite the system. This problem can be easily solved by file level recovery. It takes much less time to fix the issue. If you still want faster recovery speed, you can try Vinchin Instant Recovery technology.
