Veeam Backup for Windows recovery what am i doing wrong


Userlevel 1

so I am using Windows backup agent for Windows on my desktop stored on my NAS. however, I wanted to test it so I went to Virtualbox created a generic Windows 11 VM added some files and programs and installed Veeam for Windows, and created a backup. the backup finishes with no problem. I then created a different VM using the same settings as the first one. and tried to recover the test VM. but every time I attempt a bare metal restore I am faced with 

Restoring (C:) Error: Failed to decompress LZ4 block: Bad crc (origaal crc: e230c ...
Restore failed: Failed to decompress LZ4 block: Ba Restoring (C:) Error: Failed to decompress LZ4 block: Bad crc (original crc:
Saving restore logs Error: Unable to save recovery | e230c2bb, current crc: d7baf3cf). Failed to download disk
'Volume[227052a4-8674-407e-9278-b900d454d9f3}'. Agent failed to process
method {Data Transfer.SyncDisk}. Exception from server: Shared memory
connection was closed. Failed to upload disk. Skipped arguments:
[2714b7c9-3652-4f04-8776-130f270aeb6b];

So I booted the original and verified all of windows were intact by running chkdsk, dism, and sfc scans, and all came back good.

I then ran a full new backup on a USB drive. I tried restoring using that it also failed with the same error.

 

So I have 2 questions that I need some help with, 1 is this issue fixable?

 

and 2 is there a way to test these backups to avoid this from happening? I do have a storage-level corruption guard turned on for the backups.

 

Thank you in advance

Hello @Midnight2ss  have you check this kb: https://www.veeam.com/kb1795

 

Have you try to test your backup only for a file level restore?

Hi @Midnight2ss - I think a similar issue occurs when attempting to restore Win Server 2022 and creating your restore media on 2022; to resolve, you need to create restore media on a lesser version like 2019 (for now). Do you have a Win 10 system you can create your restore media on, then reattempt to do your test restore of your Win11 system?

I also wonder if the issue is EFI-related to the VM. In VMware I have issues with EFI-created VMs (sorry..can’t recall the error I got as it was a few mos back). Can you restore to a ‘legacy BIOS’ based VM? I also like the idea @Stabz suggested to at least try a file and/or Volume-level restore to see if even those will work.

Let us know.

i downloaded the ISO from the machine that took the backup as well as the one posted on Veeams website, i did try the EFI which got further but it failed because the disk was gbt.

Hi @Midnight2ss - Ok, so you created the recovery media ISO on the source machine? ...which is normally the correct thing to do. I’m curious if you create a Win10 VM and create recovery media on it then use it to recovery your Win11 VM if it would work.
