Steve,
Thanks for your reply. I thought something like this was possible but
had/have no idea how to set it up. Do I need the Tivoli Storage Agent for
this? Unfortunately when IBM shipped the latest base level of TSM, they
forgot to include the Tivoli Storage Agent so I am in the process of trying
to get the base level CD now. If I don't need the Tivoli Storage Agent, can
I do what you described using only the TSM server? I'm just not sure how to
get this all setup but I think once I do, it will save alot of headaches as
I think I should be able to backup our Notes files systems much faster
since the Notes Mail files are stored on a Windows 2000 file server with a
SAN attached drive. Right now they are backed up the conventional way
across the LAN/WAN and it takes a very long time. Instead of me bothering
you too much and wearing out my welcome, is there a manual you know of that
explains how to do all this?
Thanks much for your help and patience,
John

 John,                                                                      
                                                                            
 Server to server will only move data over the wan, there is no lanfree     
 opti=on at this time.                                                     
                                                                            
 If you are only using second site for backup then there is no need for     
 TSM2= at all.                                                             
                                                                            
 Just define your second site library and drives with an new device class   
 an=d stgpools on TSM1                                                     
 Start a backup stgpool and magically, data will transfer to the second     
 site.                                                                      
                                                                            
 I'm doing something like this:                                             
 TSM DB and logs are (AIX) mirrored and my diskpools are split with =BD at  
 e=ach site in separate pools.                                             
 Primary stgpool data flow is diskpool@1->diskpool@2->tapepool@2->          
 tapepool@1=                                                                
 .  The tapepool@2 is normally access=3Dunavailable, so it is usually       
 skippe=d and data goes straight to tapepool@1.                            
 During daily migration I point diskpool@1 directly to tapepool@2.          
                                                                            
 All backup stg goes to backuppool@2                                        
                                                                            
 In the event of a disaster, the tsm instance is switched to the second     
 site=.  DB and logs run on mirrors and nothing is lost there.  Data in    
 disk stgp=ools is lost and can either be recovered from backuppool@2 or   
 marked as des=troyed and backed up again.  Primary backups are made to go 
 to second site =                                                           
 by making tapepool@2 available.                                            
                                                                            
 Yes its complex, but it works.

 Here is our current setup. We have 2 TSM systems. TSM1 which is where all  
 the TSM clients backup to at night. TSM2 is offsite and only used for      
 keeping a second copy of the TSM1 data using the "BACKUP STGPOOL" command. 
 They are fiber connected like this:                                        
                                                                            
          Location 1            |        Location 2                         
  ------------------------------|----------------------------------         
                                          |                                 
                                          |                                 
               Shark1             |              Shark2                     
                     |                    |                   |             
 TSM1 - 2109 - 2029 =3D=3D 2029 - 2109 - TSM2                               
                    |                     |                   |             
          3494 Library1      |         3494 Library2                        
                                                                            
                                                                            
 Both TSM1 and TSM2 have a fiber attached 3494 Library in their respective  
 locations.                                                                 
 Both TSM1 and TSM2 have a fiber attached shark in their respective         
 locations.                                                                 
 We have a few TSM clients that are fiber attached to the Shark drive on    
 TSM1 give that the amount of storage area for that server is rather large. 
                                                                            
 From my understanding, there are LAN free and Server Free options so I     
 would think that I should be able to set it up so TSM1 sends data directly 
 from it's 3494 Library to TSM2's 3494 Library via fiber without having to  
 send the data over ethernet.  I'm a little confused on how I make this so. 
 Or for that matter, what my best strategy is at this point. Do I need the  
 Tivoli Storage Agent for this? Would it make the transfer faster? The data 
 is being sent right now but it seems to be pretty slow given that it       
 should                                                                     
 be sending the data via fiber (at least I think).                          
                                                                            
 Can someone shed some light on what my best strategy here is? Or maybe a   
 suggestion on a publication to read for optimising our environment. I just 
 want to make sure that data going from TSM1 to TSM2 is getting there as    
 fast as possible and also that the TSM clients with fiber attached Shark   
 Drives are being backed up as fast as possible.                            
                                                                            
 Thanks much,
