[MERGED] VEB backups failing: Data error

Veeam Logoby shannyla » Tue Mar 08, 2016 1:29 pm

Trialling VEB as a potential and logical add-on to our Veeam infrastructure, but have run into an issue on my trial machine.

Error I'm getting is:

Code: Select all
08/03/2016 12:50:25 :: Error: Data error (cyclic redundancy check). Failed to read data from the file [\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy4]. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}. Exception from server: Data error (cyclic redundancy check). Failed to read data from the file [\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy4]. Unable to retrieve next block transmission command. Number of already processed blocks: [150591]. Failed to download disk. 

Ayone any thoughts?

Hi Doug,

Is that failing while backing up the OEM or recovery partition?

Any recommendations on rebuilding this partition from scratch?

Hello,

I came across similar issue few days ago. Next scheduled incremental backup failed with error below:

Code: Select all
11/14/2017 8:16:40 AM :: Error: The device is not ready. Asynchronous read operation failed Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}. Exception from server:
The device is not ready. Asynchronous read operation failed Unable to retrieve next block transmission command. Number of already processed blocks: [0]. Failed to download disk. 


I was able to get it working by excluding recovery partition. I'v opened ticket with Veeam support (its AfW free version, case # 02382242) but it was not very helpfull. Recovery parition is helathy as I can boot computer from it. It is 300MB in size and disk management reports 100% usage but I think it's because it can't be accessed. Anyone faced this issue and can share how to get it solved?

No one faced such issue? Is recovery partition necessary to do a bare metal recovery? Or UEFI and system partitions are enough? If yes - then I can live without necessity to backup recovery partition.
