`<CommonParameters>`

This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see [ Microsoft Docs](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters?view=powershell-7).

## Output Object
The cmdlet returns the `VBRFCDInstantRecoverySession` object that contains settings of FCD instant recovery session.

## Examples

::: example
### Example 1. Starting FCD Instant Recovery Session for all Disks

This example shows how to start FCD instant recovery session for all backed-up disks available in the `Databaseo5` backup. The cmdlet will publish disks to the `Workload-C` cluster.

```
$backup = Get-VBRBackup -Name "Database05"
$restorepoint = Get-VBRRestorePoint -Backup $backup
$targetCluster = Find-VBRViEntity -Name "Workload-C" -HostsAndClusters
$publishingSession = Start-VBRFCDInstantRecovery -RestorePoint $restorepoint[2] -TargetCluster $targetCluster
```

Perform the following steps:

1. Run the [`Get-VBRBackup`](get-vbrbackup.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$backup` variable.
2. Run the [`Get-VBRRestorePoint`](get-vbrrestorepoint.md) cmdlet. Specify the `Backup` parameter. Save the result to the `$restorepoint` variable.

   The `Get-VBRRestorePoint` cmdlet will return an array of restore points. Consider that the array numbering starts with 0. In our example, the third restore point will be used.

3. Run the [`Find-VBRViEntity`](find-vbrvientity.md) cmdlet. Specify the `Name` parameter value. Provide the `HostsAndClusters` parameter. Save the result to the `$targetCluster` variable.
4. Run the `Start-VBRFCDInstantRecovery` cmdlet. Set the `$restorepoint` variable as the `RestorePoint` parameter value. Set the `$targetCluster` variable as the `TargetCluster` parameter value. Save the result to the `$publishingSession` variable.

::: example
### Example 2. Starting FCD Instant Recovery Session for Specified Disks

This example shows how to start FCD instant recovery session for the `Disk1` disk with the following settings:

- The cmdlet will set the `RestoredDisk1` to the virtual disk that that is mounted to the datastore.
- The cmdlet will set the `FCD-Disk1` to the FCD that is registered on the `Workload-C` cluster.

```
$backup = Get-VBRBackup -Name "Database backup"
$restorepoint = Get-VBRRestorePoint -Backup $backup
$targetCluster = Find-VBRViEntity -Name "Workload-C" -HostsAndClusters
$diskMapping = New-VBRFCDInstantRecoveryMappingOptions -NameInBackup "Disk1" -MountedDiskName "RestoredDisk1" -RegisteredFCDName "FCD-Disk1"
$publishingSession = Start-VBRFCDInstantRecovery -RestorePoint $restorepoint[2] -TargetCluster $targetCluster -MappingOptions $diskMapping
```

Perform the following steps:

1. Run the [`Get-VBRBackup`](get-vbrbackup.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$backup` variable.
2. Run the [`Get-VBRRestorePoint`](get-vbrrestorepoint.md) cmdlet. Specify the `Backup` parameter. Save the result to the `$restorepoint` variable.

   The `Get-VBRRestorePoint` cmdlet will return an array of restore points. Consider that the array numbering starts with 0. In our example, the third restore point is used.

3. Run the [`Find-VBRViEntity`](find-vbrvientity.md) cmdlet. Specify the `Name` parameter value. Provide the `HostsAndClusters` parameter. Save the result to the `$targetCluster` variable.
4. Run the [`New-VBRFCDInstantRecoveryMappingOptions`](new-vbrfcdinstantrecoverymappingoptions.md) cmdlet. Specify the `NameInBackup`, `MountedDiskName` and `RegisteredFCDName` parameter values. Save the result to the `$diskMapping` variable.
5. Run the `Start-VBRFCDInstantRecovery` cmdlet. Set the `$restorepoint` variable as the `RestorePoint` parameter value. Set the `$targetCluster` variable as the `TargetCluster` parameter value. Set the `$diskMapping` variable as the `MappingOptions` parameter value. Save the result to the `$publishingSession` variable.

### Example 3. Starting FCD Instant Recovery Session with Redo Logs Redirection

This example shows how to start FCD instant recovery session for the `Disk1` disk. The cmdlet will write redo logs to the `VeeamDatastore` datastore. The datastore is assigned the `Virtual SAN Default` Storage Policy.

```
$server = Get-VBRServer -Name "tech.local"
$datastore = Find-VBRViDatastore -Server $server -Name "VeeamDatastore"
$storagePolicy = Find-VBRViStoragePolicy -Server $server -Datastore $datastore -Name "Virtual SAN Default"
$backup = Get-VBRBackup -Name "Database backup"
$restorepoint = Get-VBRRestorePoint $backup
$targetCluster = Find-VBRViEntity -Name "Workload-Cluster" -HostsAndClusters
$publishingSession = Start-VBRFCDInstantRecovery -RestorePoint $restorepoint[2] -TargetCluster $targetCluster -CacheDatastore $datastore -StoragePolicy $storagePolicy
```

Perform the following steps:

1. Get the datastore:

   1. Run the [`Get-VBRServer`](get-vbrserver.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$server` variable.
   2. Run the [`Find-VBRViDatastore`](find-vbrvidatastore.md) cmdlet. Specify the `Server` and `Name` parameter values. Save the result to the `$datastore` variable.
   3. Run the [`Find-VBRViStoragePolicy`](find-vbrvistoragepolicy.md) cmdlet. Specify the `Server`, `Datastore` and `Name` parameter values. Save the result to the `$storagePolicy` variable.

2. Run the [`Get-VBRBackup`](get-vbrbackup.md) cmdlet. Specify the `Name` parameter value. Save the result to the `$backup` variable.
3. Run the [`Get-VBRRestorePoint`](get-vbrrestorepoint.md) cmdlet. Specify the `Backup` parameter. Save the result to the `$restorepoint` variable.

   The `Get-VBRRestorePoint` cmdlet will return an array of restore points. Consider that the array numbering starts with 0. In our example, the third restore point will be used.

4. Run the [`Find-VBRViEntity`](find-vbrvientity.md) cmdlet. Specify the `Name` parameter value. Provide the `HostsAndClusters` parameter. Save the result to the `$targetCluster` variable.
5. Run the `Start-VBRFCDInstantRecovery` cmdlet. Specify the following settings:

   - Set the `$restorepoint` variable as the `RestorePoint` parameter value. 
   - Set the `$targetCluster` variable as the `TargetCluster` parameter value. 
   - Set the `$datastore` variable as the `CacheDatastore` parameter value.
   - Set the `$storagePolicy` variable as the `StoragePolicy` parameter value.
   - Save the result to the `$publishingSession` variable.
