SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Server administrators often configure backups but never verify them, and shared storage across machines remains abstract until built by hand. This Skill walks a learner through creating an Azure Storage account, mounting an Azure Files SMB share from multiple machines, and protecting a VM with a Recovery Services Vault — including performing a real file-level restore to prove the backup works. ## Core Features & Use Cases - Storage Account Provisioning: Create a StorageV2 account with the right redundancy tier (LRS/ZRS/GRS) and access tier using Az PowerShell. - Azure Files SMB Mounting: Create a file share and mount it as a persistent drive letter on a Windows VM, with guidance for port 445 blocking issues. - VM Backup and File-Level Restore: Configure a Recovery Services Vault, run an on-demand backup, delete a file, mount the recovery point, and verify the restored file by hash. - Use Case: An MSSA learner in the Server & Cloud Administration track completes project 7 by backing up their project-#5 VM and restoring a deliberately deleted file, building the restore muscle memory most admins skip. ## Quick Start Ask the Mentor to start the sca-storage-and-backup project and walk you through creating an Azure storage account, mounting an Azure Files share, and restoring a file from a VM backup.

Frequently Asked Questions about sca-storage-and-backup

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I mount an Azure Files SMB share on a Windows VM?

Mount an Azure Files share by saving the storage account key with cmdkey, then running New-PSDrive with the -Persist flag against \\<account>.file.core.windows.net\<share>. The share appears as a drive letter and survives reboots.

How do I restore a single file from an Azure VM backup?

Use Mount-AzRecoveryServicesBackupItemFile to mount a recovery point as a drive on the VM, copy the file back, and verify it with Get-FileHash. Dismount with Dismount-AzRecoveryServicesBackupItemFile when finished.

Why does my Azure Files mount fail with system error 53?

System error 53 or timeouts usually mean outbound TCP port 445 is blocked by your ISP or corporate network. Test with Test-NetConnection -Port 445; workarounds include VPN, private endpoints, or mounting only from an Azure VM.

What is the difference between LRS, ZRS, and GRS storage redundancy?

LRS keeps three copies in one zone and is cheapest, ZRS spreads copies across three zones in a region, and GRS adds a replicated copy in a paired region at roughly double the cost. LRS suits labs; GRS or ZRS fits production data.

Does Azure backup work if the VM is deallocated?

Yes, backups use VM snapshots so they run even when the VM is deallocated. However, the one-time backup agent installation requires the VM to be running at least once.

What are the limitations of this Azure backup lab?

The lab covers standard storage accounts, key-authenticated Azure Files SMB, and RSV VM backup only. It does not cover Entra Kerberos identity-based auth, Azure NetApp Files, Azure Backup Server, or immutability features like Multi-User Authorization.
