Backup-AzKeyVaultSecret Reference Module: Az.KeyVault

Backs up a secret in a key vault.

Syntax Backup-AzKeyVaultSecret [-VaultName] [-Name] [[-OutputFile] ] [-Force] [-DefaultProfile ] [-WhatIf] [-Confirm] [] Backup-AzKeyVaultSecret [-InputObject] [[-OutputFile] ] [-Force] [-DefaultProfile ] [-WhatIf] [-Confirm] [] Description

The Backup-AzKeyVaultSecret cmdlet backs up a specified secret in a key vault by downloading it and storing it in a file. If there are multiple versions of the secret, all versions are included in the backup. Because the downloaded content is encrypted, it cannot be used outside of Azure Key Vault. You can restore a backed-up secret to any key vault in the subscription that it was backed up from. Typical reasons to use this cmdlet are:

You want to escrow a copy of your secret, so that you have an offline copy in case you accidentally delete your secret in your key vault. You added a secret to a key vault and now want to clone the secret into a different Azure region, so that you can use it from all instances of your distributed application. Use the Backup-AzKeyVaultSecret cmdlet to retrieve the secret in encrypted format and then use the Restore-AzKeyVaultSecret cmdlet and specify a key vault in the second region. (Note that the regions must belong to the same geography.) Examples Example 1: Back up a secret with an automatically generated file name Backup-AzKeyVaultSecret -VaultName 'MyKeyVault' -Name 'MySecret' C:\Users\username\mykeyvault-mysecret-1527029447.01191

This command retrieves the secret named MySecret from the key vault named MyKeyVault and saves a backup of that secret to a file that is automatically named for you, and displays the file name.

Example 2: Back up a secret to a specified file name, overwriting the existing file without prompting Backup-AzKeyVaultSecret -VaultName 'MyKeyVault' -Name 'MySecret' -OutputFile 'C:\Backup.blob' -Force C:\Backup.blob

This command retrieves the secret named MySecret from the key vaultnamed MyKeyVault and saves a backup of that secret to a file named Backup.blob.

Example 3: Back up a secret previously retrieved to a specified file name $secret = Get-AzKeyVaultSecret -VaultName 'MyKeyVault' -Name 'MySecret' Backup-AzKeyVaultSecret -Secret $secret -OutputFile 'C:\Backup.blob' C:\Backup.blob

This command uses the $secret object's vault name and name to retrieves the secret and saves its backup to a file named Backup.blob.
