Veeam Backup & Replication lets you restore linked clone VMs – VMs that were deployed from a VM template using the fast provisioning technology. There are several mechanisms for processing linked clone VMs.
Restore of Existing VMs
If you are restoring a vCD linked clone VM that exists in the vCloud Director hierarchy, the restore process includes the following steps:
- Veeam Backup & Replication uses the captured vApp metadata to define the initial settings of the VM.
- Veeam Backup & Replication calculates a signature for the consolidated VM disk in the backup file (containing the VM template data and data of the delta file) and the signature for the VM existing in vCloud Director. Veeam Backup & Replication then compares the disk signatures to define what data blocks have changed.
- Veeam Backup & Replication restores only changed data blocks from the backup file and writes them to the user delta file.
