Troubleshooting

NetVault Backup 10.x service, netvault-pgsql, does not start on Windows

To see if the following message is displayed, check the Windows Event Viewer: PDT FATAL: lock file “postmaster.pid” already exists.

NetVault Backup 10.x uses a PostgreSQL database. If the PostgreSQL database does not start, NetVault Backup cannot start. To correct this issue, delete the “postmaster.pid” file from the location referenced in the log and restart the NetVault Backup Server. For more information, see https://support.questcom/netvault-backup/kb/122475.

Backup job fails while using VSS snapshot

If a backup job is stopped or fails while a VSS snapshot is being used, the plug-in might not clean up the VSS snapshot. If this issue occurs, you can use a tool such as Microsoft CLI diskshadow.exe to remove the snapshot.

4
Using the Shadow copy ID field from that entry, run the following command:
delete shadows ID <ShadowCopyIDofAbortedOrFailedJob>
5
Navigate to <installationDirectory>\tmp\Hyper-V, and delete the directory with the VM name used during the stopped or failed job.
