LAN Server and LAN Manger Support (Jan 94)
------------------------------------------

     The OS/2 Agent for ARCserve 4.x and 5.x will now support
LAN Server and LAN Manager.  The agent used to be able to backup
and restore only the Extended Attributes and the file data infromation.
Now, we are able to backup and restore the Access Control Lists
(ACL) containing user permissions information.  Even if the user
restores the file/directory to a different location on their server,
the ACLs will also point to that location.  The following is the
steps involved in doing a backup and restore.


I. To create a clean backup of your LAN Server/LAN Manager server:

     1) Make sure LAN Server/LAN Manager is running. (after NET START
        SERVER was executed)

     2) Submit backup job as usual.

     3) During backup, DO NOT change user account infromation and
        file resource management when backup is on the file NET.ACC.


II. To Restore file permissions:

     1) Make sure LAN Server/LAN Manager is running. (after NET START
        SERVER was executed)

     2) Submit restore job including the directory/file where the
        permission needs to be restored.

     3) Permissions will be restore minus any permissions for users
        that was deleted after the backup.

        Example:
             Daily backups are done overnight.  A user MIKE deleted
        some important files by mistake.  The user MIKE was promptly
        deleted from your network and you restore the directory.
        All file data and permissions are restored, even if the restore
        was to a different directory.


III.  To restore USER and GROUP infromation:

     1) As opposed to I. and II. above.  Make sure LAN Server is DOWN.

     2) Bring up agent.

     3) Submit job to ONLY restore the NET.ACC file to it's appropriate
        directory.  For LAN SERVER, this would be the \IBMLAN\ACCOUNTS
        directory.  For LAN MANAGER, it would be the \LANMAN\ACCOUNTS
        directory.
     NOTE: For LAN SERVER people, there is something called the
           Domain Controller Database.  These files should be restored
           at this time when the server is down.  The database is in
           the directory \IBMLAN\DCDB.

     4) Bring up LAN SERVER/LAN MANAGER.

     5) Submit job to restore the rest of the Server.
     NOTE: It's important to restore the files AFTER the NET.ACC is in
           place because if the users information was not on the system,
           the ACLs for those lost users won't be restored.


Access Control List (ACL) Support - How we back it up
-----------------------------------------------------

Access Control Lists (ACL) are used by LAN Server and LAN Manager.
Each file or directory on the server can have one ACL associated with it.
ACLs contain a number of entries, each entry is identified by a user or
group and their permission for the file/directory.

The OS/2 Agent has hooks into the LAN Server/LAN Manager.  These hooks are
inside the file LS_ACL.DLL.  In order for OS/2 Agent to backup these ACLs,
we require that LAN Server/LAN Manager be active.  If the user doesn't have
either of these packages, the agent will still function normally as before.
(although we still need the LS_ACL.DLL in order to execute)
