A couple of things. What is the version of your NW server? Also is the network connectivity between the server and the client ok? You would need to ensure that you are able to ping the server by name from the client and vice versa. The important thing is that the ping should be by name not just by IP address.

Can you explain this: "But while installation, I don't see SQL option in client backup configuration, only filesystem."?

I assume you're using wizard so you didn't install it on server thus you could not use wizard to configure SQL backup.

Did you try SQL backup initiated from client (GUI)?

Network work well, all names of this server ping and resolves without problem.
Client software freeze on first db from the MSSQL.
Networker version 7.5 build 179



Yes, I'm about wizard. On server client and module installed. Now client configured manualy

Have you checked SQL module log? (not XBSA) It should be there....

Sql mod log are empty.
One thing, after MSSQL backup starts Networker wants tape for Default group (MSSQL in another group, and pools tuned correct), I think it's something related with index (maybe it wants save index to this group). But I don't find related settings.

Try to run for start SQL backup from client - you can set debug level as well. And see what failure do you get.

Perhaps try SQL module 5.1.1 if possible, just to see if you get the same result. We've had a few issues with 5.2 that was resolved by downgrading.
