how to create backup of blob storage give full step by step details with screenshot

Hello kuldeep singh, Thanks for reaching out about creating a backup for your Azure Blob Storage. The recommended and fully managed way to handle this is by using Azure Backup, which supports both operational backup (continuous, local protection inside your storage account for quick point-in-time restores) and vaulted backup (offsite copies stored in a Backup vault with long-term retention).

This approach automatically enables important features like blob versioning, soft delete, and a delete lock to protect against accidental changes or deletions. Quick High-Level Steps:

1. Create a Backup vault (if you don't have one yet).
2. Assign the "Storage Account Backup Contributor" role to the vault on your storage account(s).
3. Create or select a backup policy that defines the schedule and retention.
4. Configure protection for your storage account from the Azure portal (or directly from the storage account's Data protection blade).

You can protect multiple storage accounts with the same policy, and it works only for block blobs (the most common type).

For full step-by-step instructions with screenshots in the portal, please refer to these official Microsoft docs:

• Overview of Azure Blobs backup (explains operational vs vaulted backup):https://learn.microsoft.com/en-us/azure/backup/blob-backup-overview
• Configure and manage backup for Azure Blobs (detailed portal guide):https://learn.microsoft.com/en-us/azure/backup/blob-backup-configure-manage
• Tutorial: Configure vaulted backup (if you need offsite protection):https://learn.microsoft.com/en-us/azure/backup/blob-backup-configure-tutorial

Once protection is enabled, you can monitor jobs and perform restores directly from the Backup vault.

If you run into any permission issues, validation errors, or need help with PowerShell/CLI commands instead of the portal, feel free to share more details (like any error messages you're seeing) and I'll guide you further.

Thanks
