Hello

We had the same problem some time ago and we found that it was due to the 
anti-virus software which
slow down the process especially if the saveset has many small files. So we 
deactivate this software ( for
outcoming files ) so we can keep a good save speed.

For restore speed, some folks here investigate working with DFS on W2k which 
could lead to my sense ( i
am not a w2k expert ) to break the big saveset into small ones without any 
changes for application which
will increase save speed ( better to use 4 channels than one to save the same 
amount of data ).

Hope this will help

Francis

 





Greetings,

We are trying to back up a save set that is 120gb. It is a W2K node, being
backed up to a SOL 9 /SBU 6.1.3 server. Its starts at about 5mb per sec,
(acceptable), then drops to 5kb per second (unacceptable!) after some time.

My question is X fold;

a)       Is there any special trick to getting large file systems to backup
over the network when the node is W2K. (besides replacing it with Solaris
:-) )
b)        Any know issues with backing up to SOL box's from a W2k node.



Regards
Grant,
