After receiving a Sev3 (Severity 3) Azure Monitor Alert related to VM Availability, my virtual machine (VM) experienced data loss. How can I investigate the cause of this issue, recover the lost data, and prevent such incidents in the future?

Hi yogesh bohra
To fix data loss caused by a Severity 3 (Sev3) Azure Monitor alert about VM availability, follow these steps to investigate, recover data, and prevent future issues.

Investigating the Cause of Data Loss:

1.Look at the alert details in Azure Monitor to understand what caused it. Check the time, affected resources, and error messages.

2.Use Azure Monitor to check the VM’s performance and availability. Look for issues like low resources (CPU, memory, disk) or network problems.

3.Check the Azure Activity Log for any actions, like restarts or changes, that happened when the alert was triggered.

4.If you have Azure Backup, check if the backups were successful before the issue. Look for alerts about backup failures.

Recovering Lost Data:

1.If backups exist, use Azure Backup to restore your VM or files from the most recent backup. Go to the Recovery Services vault, select your VM, and click "Restore."

2.If no backup is available, check if you have snapshots or other storage like Azure Blob Storage to recover files.

3.Look for any temporary files or cached data that might help recover some of the lost data.

Preventing Future Incidents:

1.Set Up Alerts: Create more detailed alerts based on VM availability. Set them to notify you early so you can act before data is lost.

2.Regular Backups: Set up daily backups for your VMs and test the restore process to make sure your data is safe. Enable soft delete to protect backups from being deleted accidentally.

3.Check Resource Allocation: Analyze VM usage and consider resizing or optimizing workloads to prevent resource problems that can affect availability.

4.Use Automation: Automate VM management during off-hours to avoid issues with availability.

5.Conduct Regular Audits: Perform regular checks on your Azure settings, backup policies, and alerts to make sure everything is working as it should.
To fix data loss caused by a Severity 3 (Sev3) Azure Monitor alert about VM availability, follow these steps to investigate, recover data, and prevent future issues.

Hi yogesh bohra
1.If you accidentally deleted temporary files, they might still be in the Recycle Bin. Open it, find the file, right-click, and select "Restore."
2.If you enabled File History, go to Settings > Update & Security > Backup. Click "More options" and select "Restore files from a current backup" to find and restore your temporary files.

Hi yogesh bohra
Here are steps to recover data from temporary files or cached data in an Ubuntu virtual machine:

1.Look in the /tmp directory for any files that may still be there.
2.Tools like TestDisk, PhotoRec, or extundelete can recover deleted or lost files.
3.If you have the virtual hard drive file (.VHD, .VMDK, .VDI), attach it to a new Ubuntu VM to recover data.
4.Restore lost data from your backups.
5.Look in application or service directories for cached data that might still be available.
6.Tools like Scalpel, Foremost, or ext4magic can scan the file system to recover deleted files.
7.Use advanced data forensics tools for in-depth data recovery if needed.

Hey Yogesh,

the classic "VM went on a break and took your data with it" scenario. A Sev3 alert is Azure’s way of saying, "Mate, your VM’s having a nap, but it might’ve forgotten to save its work."

First, check if your VM’s just having a wobble restart it and see if it wakes up. If it’s properly kaput, check your backups (you 'do' have backups, right?). Azure Backup or snapshots should have your back. If not, it’s time to have a serious chat with your future self about backup policies.

For the database, if you’ve got a recent dump or backup, restore it. If not, you might need to call in the data recovery pros (and maybe a therapist).

To stop this happening again, set up proper monitoring, regular backups, and maybe an auto-recovery plan. Azure’s got your back, but only if you tell it to.

RGDS,

Alex
