Instant Disk Recovery

In this article

    With Instant Disk Recovery, you can immediately restore VM disks from a backup file and use one of the following options:

    • Perform Instant Disk Recovery. Use this option to publish recovered disks to the production environment.
    • Perform Instant First Class Disk (FCD) Recovery Use this option to register recovered disks as FCDs in the production environment. FCDs are a type of improved VMDK that allow to perform different tasks: create snapshots, delete and restore data stored on VMDK without attaching these disks to a VM.

    Use Instant Disk Recovery if you need to:

    • Recover VM disks, not an entire VM. Otherwise, use Instant Recovery.
    • Recover VM disks and keep the target VM (to which you want to attach recovered disks) turned on. If the VM can be turned off, use Virtual Disks Restore.
    • Convert recovered VM disks to FCDs and migrate them to your production environment.

    Veeam Backup & Replication performs Instant Disk Recovery and Instant FCD Recovery using vPower technology.

    The main steps of Instant Disk Recovery are the following:

    1. Veeam Backup & Replication checks whether the vPower NFS datastore is mounted to the ESXi host and contains VMDK files of the recovered disks.
    2. [If you replace an existing disk] Veeam Backup & Replication unmounts and deletes the existing disk.
    3. The recovered disks are connected to the target VM.
    4. Veeam Backup & Replication initiates a creation of a protective snapshot for the target VM. If Instant Disk Recovery process fails, the protective snapshot guarantees no data loss.
    5. Veeam Backup & Replication writes changes made to the recovered disks to redo logs on the vPower NFS server.

    The main steps of Instant FCD Recovery are the following:

    1. Veeam Backup & Replication initiates a restore session.
    2. Veeam Backup & Replication connects to a target VMware cluster and mounts vPower NFS datastore to all ESXi hosts added to the target VMware cluster.
    3. Veeam Backup & Replication mounts recovered disks and publishes them to the target vPower NFS datastore.
    4. Veeam Backup & Replication registers published disks as FCDs to the target vPower NFS datastore.
    5. Veeam Backup & Replication initiates a creation of a protective snapshot for every FCD. If the Instant FCD Recovery process fails, the protective snapshot guarantees no data loss.
    6. The recovered disks are unmounted from the vPower NFS datastore.

    Note

    Mind the following:

    • If you specify the custom datastore to keep the redo logs, information on the FCD snapshots will be stored in the instant recovery session logs.
    • Veeam Backup & Replication does not remove the mounted vPower NFS datastore from a VMware cluster.

    Both Instant Disk Recovery and Instant FCD Recovery must be finalized:

    • [For the Instant Disk Recovery option] First, test the recovered disks and then decide whether to publish them to the production environment or stop publishing the disks.
    • [For the Instant FCD Recovery option] Migrate the recovered disks to the production environment or stop publishing them.

    To publish the disks, Veeam Backup & Replication uses the Quick Migration mechanism. For details, see Quick Migration.
