Hi Stefan. You captured my attention about your comments
regarding the backup throughputs. What do you consider a
good throughput. Our server is currently capable of transferring
1.5GB in 6minutes over a High Speed switch. The network data
transfer rate is 10,104 KB/sec while aggregate data transfer rate
is 4,292 KB/sec. Do you think we can get better performance?
Perhaps 1.5GB in 3minutes? Comments or suggestions are
appreciated.

Angel

   Actually I would be worried about through put for both backups.
   Getting
   12gig/hour on a local backup is not what I would consider good. Have
   you
   spoken with BMC about this at all? We get about 12gig/hour over the
   network
   to ADSM.

   Subject: SQL BACKTRACK for SYBASE


    We are running Sybase version 11.02 on a HP machine.  We are trying
   to back
   this up via Backtrack to
   our ADSM 3.1.2.40 aix version 4.2 server.

   When we natively backup from the HP server we get 3-4 m/s
   When we use the SQL BACKTRACK software from BMC we are getting 1-1.4
   m/s

   Is there anybody out there that is using Backtrack and if there is
   can you
   give us
   any suggestions as to why we are seeing such bad performance.

   Is there any options we can check to try to improve our throughput
   numbers...

   Any suggestions would be greatly appreciated...

   thanks
