NetVault Plug-in for SnapMirror to Tape 10.0.5 - User Guide

Mirroring process

Using the NetApp SnapMirror utility and Plug‑in for SnapMirror to Tape, you can take a snapshot from a NetApp filer and transfer it to a piece of media, and then mirror this data to a second filer. However, the plug-in does not control this aspect of the operation. It is solely handled by the NetApp utilities. For more information about this process, see the relevant NetApp documentation.

Check the Windows Event Viewer to see if it displays the following message:
PDT FATAL: lock file "postmaster.pid" already exists

To correct this issue, delete the “postmaster.pid” file from the location referenced in the log and restart the NetVault Backup Server.
After restarting the machine, the NetVault Backup Service sometimes fails to start on a Windows-based NetVault Backup Server.
Check the Windows Event Viewer to see if it displays the following message:

To correct this issue, start the Task Manager, and click Show processes from all users. You can see multiple instances of postgres32.exe running on the system. Select any one instance of this process, and click End Process to remove all instances of postgres32.exe. Then, start the NetVault Backup Service from the Configurator.
