Windows 7 SP1 x86 with latest updates and VEB 1.5.0.306 has error:

Code: Select all
Creating VSS snapshot Error: Failed to create snapshot: Backup job failed. Cannot create a shadow copy of the volumes containing writer's data. A VSS critical writer has failed. Writer name: [SqlServerWriter]. Class ID: [{a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}]. Instance ID: [{8bb1890f-6357-4a4d-9eec-50b4cc89304b}]. Writer's state: [VSS_WS_FAILED_AT_POST_SNAPSHOT].

Hello,

VEB is using Microsoft VSS to for doing backups, based on your error message I would suggest to check out VSS writers state and especially SQL Server one, there should be no faulty entries.

To do that run this command on your Windows 7 computer:
Code: Select all
vssadmin list writers

Once you detect a writer with an error state, please review Windows event log for additional info about this writer.

Thanks!

I uninstalled VEB and all sql localdb components, found and deleted all *veeam*-entries of folders and files, installed VEB again, created task and it works now.
