Azure Backup vaults – New era of snapshot backups – backup every 1h

If you think about backup in Azure – probably you think about Recovery Services vaults. But there is currently a new possibility named Backup vaults. Of the box, you can configure backups every 4 hours. Currently, it supports: VM Managed Disk Backups (Snapshot) Azure Blobs Azure PostgreSQL Databases You can create ad-hock backups using portal or PowerShell. If you using PowerShell and see an error like:

Backup-AzDataProtectionBackupInstanceAdhoc : Input provided for the call is invalid

Probably you are using wrong parameter for -BackupRuleOptionRuleName it should be:

-BackupRuleOptionRuleName “BackupDaily”

Or

-BackupRuleOptionRuleName “Daily”

Note “Default” like mentioned in Documentation. Here is a code that can be implemented in the Azure function to do backup every 1h.
