We have the standard set up of an internet facing wsus server. Which we export. And then import to the internal wsus server. Running fine. For years.
I ran a script which declines all the supersede and no longer required patches. Dropped from 250gn to 40gb
Next export worked fine
But I had to rebuild the internal one recently. And it stalled on downloading. As files were missing.
I re approved all the declines on the external one. And copied those files back in and it started working.
Why ? I mean. They were deleted by wsus own server clean up. Why would the meta data still be there ?
