Not sure as there is a lic. issue - we are trying to talk to them about this. They may not move as fast as us. We are talking about other options, we just need more time. So sorry for the delay
Actual Legato update is still in beta state and dedicated for specified
clients only.
You can still backup the SMB shares without Legato client for DSS and NAS-R3.
1. On DSS in "Config->NAS Resources->Users" add user "legato",
2. Chose "legato" user from list and add shares to access list,
3. In function "Config->Nas settings->SMB settings" add user "legato" to
superusers lists,
4. Please map DSS shares as Network Drive on your Windows with Legato Server
and client installed using "legato" user for authenticate,
5. From Menu Start->Programs->Legato NetWorker run "Networker User" program,
6. Now choose Operation->Backup from NetWorker menu and data from mapped disk
to backup.
