Ipswitch - The set of File Filters is reset to C:\Protected\**. What should I do next?

Follow

Summary

This Knowledge Base article describes the behavior of Ipswitch Failover when one or more entries in the set of File Filters are pointing to a non-existent drive letter or to a non-NTFS partition.


More Information

The set of File Filters configured for each Ipswitch Failover server pair can be found in the Ipswitch Failover Manager, under the Data: File Filters tab. The File Filters determine which files and directories are protected by Ipswitch Failover.

When Ipswitch Failover starts, the complete set of File Filters is checked for consistency. If any of the entries points to a non-existent drive letter or to a non-NTFS partition, the list of File Filters will be reset to the default value of C:\Protected\** . This is a safety measure; Ipswitch Failover requires the same drive letter configuration on the Primary, Secondary, and Tertiary (if installed) servers, and only supports protection of NTFS partitions.

Recovery Steps

The terms below refer to the Ipswitch Failover installation directory and the Windows installation directory, respectively.

Before beginning the restoration of the File Filters set, make sure you have the same drive letter configuration on the Primary, Secondary, and Tertiary (if installed) servers. If Ipswitch Failover is currently running, stop Ipswitch Failover but opt to leave the protected application running.

Ipswitch recommends the following corrective measures, which vary depending on which application is being protected:

Ipswitch Failover for File Server

  1. On the active server, delete the file <install_directory>\R2\Bin\FileServer.nfd . This will ensure all filters for network shares are recreated when Ipswitch Failover is restarted.
  2. Start Ipswitch Failover on all servers and allow the filter discovery tool to recreate the filters, and also the file <install_directory>\R2\Bin\FileServer.nfd . The filter discovery operation will not start immediately - the filter discovery tool runs at a preconfigured interval (by default, every 2 minutes).
  3. In the Log: Event Log section of the Ipswitch Failover Manager, wait for a File System Filter Change Check Task Completed message, and then check that each share has its corresponding File Filter entry under Ipswitch Failover Manager.
  4. Using the Data: File Filters page of the Ipswitch Failover Manager, manually add the following 2 entries to the File Filter set:

    <install_directory>\R2\BIN\FILESERVER.XML

    <install_directory>\R2\BIN\FILESERVER.NFD
  5. Click OK when finished. Allow the system to perform another File System Filter Change Check Task.

Ipswitch Failover for SQL Server:

  1. On the active server, delete the file <install_directory>\R2\Bin\SQLServer.nfd . This will ensure all filters for SQL Server database files and transaction logs are recreated when Ipswitch Failover is restarted.
  2. Start Ipswitch Failover on both servers and allow the filter discovery tool to recreate the filters, and also the file <install_diectory>\R2\Bin\SQLServer.nfd . The filter discovery operation will not start immediately - the filter discovery tool runs at a preconfigured interval (by default, every 2 minutes).
  3. In the Log: Event Log section of the Ipswitch Failover Manager, wait for a File System Filter Change Check Task Completed message.
  4. Using the Data: File Filters page of the Ipswitch Failover Manager, manually add the following 4 entries to the File Filter set:

    <install_directory>\R2\BIN\SQLSERVER.XML

    <install_directory>\R2\BIN\SQLSERVER.NFD

    <install_directory>\R2\BIN\*.DSN

    <install_directory>\System32\DTCLOG\**
  5. Click OK when finished. Allow the system to perform another File System Filter Change Check Task.
