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.
