My snapshot restoration on VM Linux not includs all the partition, what can i do?

Hi Arnulfo Urquijo

Based on the details you shared, the issue appears to be related to how the snapshot was taken. Azure snapshots are created at the disk level, so only the disk selected during creation is captured. If the snapshot was taken only for the OS disk, the restore process will bring back only the OS-disk partitions. Any additional partitions that existed on data disks will not appear unless those disks also had snapshots.

Please verify which disks were included in the snapshot. If your VM previously had multiple disks, each one needs its own snapshot to be recoverable. If only the OS disk snapshot exists, then only OS-level partitions can be restored.

Next, check the current partition layout on the restored VM. You can run commands such as lsblk, sudo fdisk -l, or df -h to confirm which partitions were restored and whether any unallocated space is present. If the snapshot was taken before resizing the VM, the restored disk will show the older partition structure.

If additional disks had snapshots, you can recreate managed disks from those snapshots and attach them back to the VM. If no snapshots exist for data disks, those partitions unfortunately cannot be recovered from the current snapshot.

As an alternative approach, you may create a managed disk directly from the snapshot and attach it to a new or existing VM. This sometimes provides better visibility and control when validating disk contents.

If issue persists, to know more understanding about the issue. Could you please provide below details

1.When have you taken snapshot of the disk before resizing the VM or after resizing the VM?

2.Is this snapshot for the OS disk or a data disk? How many partitions did the disk have originally?

3.After restoring, did you attach the disk to a new VM or create a VM directly from the snapshot?

4.Have you tried restoring the individual disks instead of the entire VM?

5.Could you please confirm the original VM size and the new size after the resize operation?

6.Are you performing the restore in the same Azure region where the VM was backed up?

7.Which specific partitions are missing after the restore that are critical for your operations?

8.Share output of these commands from the restored VM: lsblk -f, sudo fdisk -l /dev/sda (replace sda with your disk), and df -h

9.Any error messages during boot, SSH, or commands?

Additionally, could you please check private message and provide necessary details.
