Understood. I got the last idea before passing the investigation to support team – try to run a check disk utility in order to make sure the source volume does not contain any bad blocks.

So, checking that I found a way to mount the recovery partition and found out that it only had 19MB free. seems some update replaced the winrm.wim by a larger version.
I emptied the partition and now the backup is working again.
Just hope my system will boot cleanly.

Too happy too soon.
Today I get the device not ready error again today. The volume in question has over 200MB free.

[MERGED] Backup Recovery Partition failed

Veeam Logoby Sistemi.informativi » Thu Dec 10, 2015 11:21 am

Hello,

I tried to backup the C:\ volume (Recovery partition + EFI + System) of our B&R 8 physical server but keep failing, these are the errors:
03/12/2015 14:47:39 :: Saving Recovery partition (disk 28)
03/12/2015 14:48:02 :: Error: The device is not ready. Failed to read data from the file [\\?\Volume{548b36b0-aaaf-4edd-bd26-f7a60e3753c6}]. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}. Exception from server: The device is not ready. Failed to read data from the file [\\?\Volume{548b36b0-aaaf-4edd-bd26-f7a60e3753c6}]. Unable to retrieve next block transmission command. Number of already processed blocks: [0]. Failed to download disk.

The backup is successful if i exclude the recovery partition from it.

1)is possible to recover the server without a backup containing the recovery partition?
2)How can I fix the problem to have a full volume backup?

Thank you

Hmm...so there is no data at all in the recovery partition? Can you boot from this partition?

Yes through bare metal recovery (using Veeam Recovery Media)
2)How can I fix the problem to have a full volume backup?

Do you have any idea how it was created (vendors partition or might be during the OS upgrade)? Can you see this partition as a volume in windows explorer? Next stop would be to run a disk part:

Code: Select all
//open cmd as admin

diskpart
list disk
select disk ###
 
// replace ### with the number  of the disk you got on the previous step – most probably 0

list partition
select partition ###

// replace ### with the number of the recovery partition you got on the previous step – most probably 1

detail partition

//copy and paste info to this thread

Thanks - it looks like a regular hidden recovery partition which should be backed up as usual. Please open a support case thru Veeam Endpoint Backup > Control Panel > Technical Support an let me know the case ID. We need to check the application logs.

Hi All,

I finally got around this issue by recreating the recovery partition from RAW format to NTFS. I have 2 identical HP DL360 G9 servers, with SSD RAID disks.
For some reason one of the servers created a RAW hidden recovery partition where-as the other created an NTFS partition. The RAW one fails as Endpoint cannot read it.
Steps taken:

1. Take Veeam Endpoint backup of Windows C: partition
2. Win2012 R2 server - Install FREE Active@ Partition Manager and FREE HDD RAW Copy Tool
3. Take a backup of the RAW recovery partition with HDD RAW Copy Tool and save the data to accessible location
4. Use Active Partition Manager and/or Windows Disk Management to delete and re-create the hidden recovery partition in an NTFS format
5. Copy the backed up data into the new recovery partition, edit partition details and NTFS access permissions
6. Test booting into recovery mode for success - confirmed. Test Endpoint 'Entire Machine' backup for success - confirmed.

Hope this helps - cheers,
Jamie G
