Examples

Start-VEMDBRestoreJob Example 1. [For Collections Restore] Restoring Specific Collection With Default Settings

This example shows how to restore a MongoDB collection to the original location. The collection will retain the original name. This example will also restore the admin database to the original location.

$session = Get-VEMDBRestoreSession

$database = Get-VEMDBDatabase -Session $session[0] -Name "employees"

$collection = Get-VEMDBCollection -Database $database

$restoreoptions = New-VEMDBCollectionRestoreOptions -Collection $collection[0] -NewCollectionName "home office"

$instancecreds = Get-Credential

$securepassword = Read-Host -Prompt "Enter password" -AsSecureString

$servercreds = New-VEMDBLinuxCredentials -Account "root" -Password $securepassword

$restore = Start-VEMDBRestoreJob -Collections $restoreoptions -InstanceCredentials $instancecreds -Server mongodb02 -Credential $servercreds -RestoreAdminDatabase

Perform the following steps:

Run the Get-VEMDBRestoreSession cmdlet. Save the result to the $session variable.

The cmdlet will return an array of active restore sessions. Note the ordinal number of the necessary restore session. In our example, it is the first restore session in the array.

Run the Get-VEMDBDatabase cmdlet. Set the $session variable as the Session parameter value and select the necessary session. Specify the Name parameter value. Save the result to the $database variable.

Start-VEMDBRestoreJob Example 2. [For Collections Restore] Restoring All Collections in a Replica Set With Default Settings

This example shows how to restore all MongoDB collections in the replica set to the original location. Each collection will be restored with the original name, to the same database as on the backup. If any of the collections exist on the target server, the cmdlet will overwrite them without issuing a prompt.

$session = Get-VEMDBRestoreSession

$collections = Get-VEMDBCollection -Session $session[0]

$restoreoptionsarray = @()

foreach ($collection in $collections) {

$restoreoption = New-VEMDBCollectionRestoreOptions -Collection $collection

$restoreoptionsarray += $restoreoption

}

$instancecreds = Get-Credential

$securepassword = Read-Host -Prompt "Enter password" -AsSecureString

$servercreds = New-VEMDBLinuxCredentials -Account "root" -Password $securepassword

$restore = Start-VEMDBRestoreJob -Collections $restoreoptionsarray -InstanceCredentials $instancecreds -Server mongodb02 -Credential $servercreds -Force

Perform the following steps:

Run the Get-VEMDBRestoreSession cmdlet. Save the result to the $session variable.

The cmdlet will return an array of restore sessions. Note the ordinal number of the necessary restore session. In our example, it is the first restore session in the array.

Run the Get-VEMDBCollection cmdlet. Set the $session variable as the Session parameter value and select the necessary restore session. Save the result to the $collections variable.
Declare the $restoreptionsarray variable. Assign an empty array to this variable.

Save the result to the $restore variable to be able to use it with other cmdlets.

Start-VEMDBRestoreJob Example 3. [For Collections Restore] Restoring Collections With Custom Restore Options

This example shows how to restore specific MongoDB collections to another location. The collections will be restored with different names, to a new database. This example uses a custom SSH port to connect to the target server and it will use the TLS protocol to connect to the target MongoDB deployment.

$session = Get-VEMDBRestoreSession

$database = Get-VEMDBDatabase -Session $session[0] -Name "locations"

$collections = Get-VEMDBCollection -Database $database

$restoreoption1 = New-VEMDBCollectionRestoreOptions -Collection $collections[0] -NewCollectionName "kyoto" -NewDatabaseName "users"

$restoreoption2 = New-VEMDBCollectionRestoreOptions -Collection $collections[1] -NewCollectionName "sydney" -NewDatabaseName "users"

$restoreoptionsarray = @($restoreoption1, $restoreoption2)

$instancecreds = Get-Credential

$securepassword = Read-Host -Prompt "Enter password" -AsSecureString

$servercreds = New-VEMDBLinuxCredentials -Account "root" -Password $securepassword

$restore = Start-VEMDBRestoreJob -Collections $restoreoptionsarray -InstanceCredentials $instancecreds -Server "srv18" -Credential $servercreds -InstancePort 27017 -SshPort 23 -UseTLS

Perform the following steps:

Run the Get-VEMDBRestoreSession cmdlet. Save the result to the $session variable.

The cmdlet will return an array of active restore sessions. Note the ordinal number of the necessary restore session. In our example, it is the first restore session in the array.

$session = (Get-VEMDBRestoreSession)[0]

$securepassword = Read-Host -Prompt "Enter password" -AsSecureString

$servercreds = New-VEMDBLinuxCredentials -Account "root" -Password $securepassword
