Looking for some ideas on this. I have 2 Dell servers both exactly the same in every way, same drivers, same fermware same OS same Servers. Same Tape drives (Dell PVT122 LTO2). One server call File1 the other File2. File1 backs up @ 1.2 Gig a minute. File2 @ 550 Megs a minute. I need to have this server run as quickly as the File1 server. The backup is running past the backup time frame on a daily basis. The only difference between the 2 servers is File2 has a lot more small files.
 
Well, first - alot of small files is going to be slower. You also need to look at the nics, there config, the switch - are they both connected to the same and what is it - 100MB or gig? Then look at the servers you are backing up and the same things on them. Also, do you have the agents installed on the clients.
 
Same type of NIC auto Gig enabled connected to a Fast T. No agent installed on Either server
 
the size of files and depth/length of the directory structure plays an important role in backup throughput.
To test your environment, place some big files (ie Ghost files or ARCserve backup to disk sessions which can be large archive files depending of the session size) and copy them to both servers on the same volume. Test this in a backup session to eliminate file size. This will not speed up your slow backups but will give you an indication if both environments theoretically perform the same way.
Also check the backup with your virusscanner disabled and check defragmentation of the volumes
 
Have you tried multiplexing the small files? It works GREAT!
 
Sorry but your initial statement - the same in every way cannot be true - if it is, then you have a hardware problem, if not, it's something in the OS configuration.
