Troubleshooting your video archiver
Have you received an Archiving queue full or Archiver low on resources warning? This message could be a result of disk storage speed, network card performance, total RAM and CPU usage of the server and Archiver, or a problem with the Archiver database.

How to fix the issue
The Archiver relies on the performance of multiple components to ensure a smooth archiving process. Luckily, getting to the root of the issue isn’t difficult. Below are some quick and easy solutions you can try:

Disable the disk indexing in Windows for all recording drives and make sure the drives aren’t full

Update the network card driver to the latest version from the manufacturer's web site

Make sure that the server specifications exceed the minimum requirements indicated in the Server Requirements guide for Security Center

Check the Windows Event Viewer logs for any errors or warning messages related to SQL which might indicate a database issue
