How to Take backup of Virtual Machines using Recovery Service Vault in Azure - AZ-103



To take  virtual machine backup refer this link as appears here
There is another way also to take a backup of virtual machines, AZURE Fieshare(preview) and SQL Server in Azure VM .
I’ll be explaining about virtual machine backup through Azure recovery service vault.
To achieve this open a Azure recovery service vault and go to backup option available in left pane as shown in below window: service-vault.jpg

 Click on the backup , it open a following window with the following information.
  •        Choose backup policy : Backup policy specifies frequency and time at which vm  will be backed up and for how long it will be retained .You can create new policy or use default policy. In my case I have opted default policy
  •       Backup Frequency: Daily at  11:00 PM UTC.
  •       Instant restore : Retain instant recovery snapshot for 2 days.
  •       Retention Range: Retain backup taken every day at 11:00 PM for 30 Day(s).


You can also refer an image backup-policy.jpg  shown below and click on ok .


Once you click on ok with default policy it takes you to next level to take items to backup. You should be able to see the list of Virtual  machines which exist in same region as service vault to take backup further. Refer an image items-to-backup.jpg as appears below:
As soon as you click on ok, it starts taking backup generally it takes few mins to take backup of virtual machine and after successful deployment it updates the table in backup items in Service recovery vault as shown in image backup-items.jpg


Click on Azure virtual machine , It opens a new screen and shows a last backup status  with pending You have to click again on the Virtual machine record to take backup right now.

An given below image is self explanatory like backup pre-check as passed however  with initial status pending. Click on backup and provide the date till you want to keep backup




    After successful backup  of virtual machine it shows and update last backup status as successful. It also states you about consistency level while taking backup
In general these are described as follows
Application Consistency : This is one of the potential and consistent if you have Microsoft workload and it also ensures following parameters
 1 . No data loss
2. No Corruption
3. Ensure VM boots
4. The data is consistent to the application that uses the data, by involving the application at the time of backup--using VSS.

Crash consistency: This  snapshots generally occurs when VM shuts down while taking backup  and only keeps the data that already exists on the disk at the time of backup is captured and backup.
