Why does WSUS keep metadata?

347 Views
Last Modified: 2019-04-10
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 ?

Firstly, I don't know why you're using WSUS in that way as its not ideal. Why maintain two separate WSUS deployments and export/import? Just use one if you want them to match up.

Secondly, please confirm if you mean VPN/dial in access or actually 'internet-facing' (as WSUS is not licensed for internet use.)

Anyway, I'm really not clear what you are asking. What do you want to know?

Air gapped.   The rig is not connected to the internet.  

So that's how we do it

Wsus is on a network that connects to the internet.   Not sure what you mean not licenced to use wsus over the internet.  How else would you use it ?   Just the wsus server connects.   Then we export and import to internal server    It's a standard Microsoft solution.

My question is.  I would like to just use the new updates.  

Or a smaller set.  Copying 250gb each time is painful

If I clean up wsus I can reduce the content to 40gb. But when I bring that to import.  It often complains.  Of missing files.  Even though they are all superseded /declined

Is the WSUS server accessible over the internet to clients not on your internal network or do users need to be on one of your sites or via VPN to access it?

Anyway, I'm still unsure why you are importing/exporting stuff as I may have misunderstood the purpose of your 'internal' WSUS server. is tihs on a disconnected network that cannot connect to your WSUS setup? if not, there is not normally any reason to be exporting/importing manually in this way. WSUS should handle this automatically as part of a multi-server WSUS setup.

Ok may be terminology confusing you.

Airgapped = disconnected.  

External = out side of the rig, connects to the internet

Internal = within the rig it's self

Internet facing =. The external server that has an internet connection. (Doesn't matter what type )

The internal server is not internet facing.  Hence.  Import and export


The question is only for someone familiar with importing meta data. And what you can and cannot expect from that task.    The actual details of how we are set up or connect to the internet has nothing to do with it.

Cheers

Wsus A.  External. Connects to internet downloads updates


Exported taken sent to

Wsus B.  Internal. Clients connect to this one.

It's a really common Micrsoft recommended solution for this type of set up.
