HI ,Errors when i try to backup server , it says :

- SQL VSS Writer is missing: databases will be backed up in crash---consistent state and transaction log processing will be skipped
- One or more bad blocks were detected and skipped and skipped in the source disk

I changed the destination from NAS to local and same error pop up

Hi Morad,

I would check the state of all VSS writers by "vssadmin list writers" command, you may also take a look at this KB which provides the instruction for shadow copy creation using diskshadow tool. However, I strongly recommend to perform all troubleshooting steps under the guidance of our support team.

I'm not sure that the second error about bad blocks is related to the backup repository but perhaps there are some issues on source. Anyway, our support engineers will be able to determine the root cause.

Thanks!

This KB article is specific for SQL VSS Issues with Veeam.
It helped me every time:

https://www.veeam.com/kb2095

Mostly it was a false logonaccount on the SQL VSS Writer Service.
the account under which SQL VSS Writer service is running doesn't have sysadmin role on a SQL server

Hello,

@astoinemicro As far as I see the case is under investigation but is in pending status since our engineers wait for your reply and debug logs. The best action plan is to keep working with our support team because our possibility to troubleshoot technical issues over forum posts is quite limited.

Thanks!
