Veeam Backup & Replication allows you to perform both image-level and file-level restores of backups and replicas. You can restore a virtual machine as a whole to start it on the target ESX server, recover only VM hard disks, VM files (.vmdk. .vmx and so on) or VM guest OS files and folders and save them on your local machine. VMs or files can be restored at any of the available restore points.
The restore process is always performed via the network.
When performing instant recovery, Veeam Backup & Replication creates an independent temporary copy of a VM in your VMware environment and immediately starts it (if necessary). You can also use a recovered VM for testing purposes to ensure the VM guest OS and applications are functioning properly. Instant VM recovery does not require you to extract a VM from a backup and move it across datacenter — it mounts a VM directly from a compressed backup file on a selected ESX host.
The archived image of a VM remains in a read-only state to avoid unexpected modifications. All changes to a virtual disk that take place while a VM is running are logged to an auxiliary file on the Veeam Backup server or any datastore you select. These changes are discarded as soon as a restored VM is removed.
When you perform file-level recovery for Windows OS, the Veeam transport service running on the target host or backup repository mounts the VM file system to the local drive via Veeam's proprietary driver. After that, you can copy necessary files and folders to your local machine drive and save them anywhere within the network or simply point any applications to the files and use them normally. The backup file or replica will remain read-only no matter what you do.
