It seems I still have to clarify some things...
1) Using FTP to transfer files files from source-servers to my Backup Exec-server works almost perfectly. It will generate an average throughput of 270 - 275 Mbps... And peaks at 300 Mbps. I am fine with this.
2) Using BE to transfer the exact same files from the exact same source-servers to the exact same Backup Exec-server, under the same conditions, will generate an average 150 Mbps (tests done earlier this day shows the average decreased to about 85 Mbps) and one peak at 280 Mbps.
3) No tapedrivers/autoloaders involved in the test.
4) FTP transfers are directed to the same RAID-devices as when using BE.
I have updated nic-drivers on all involved servers.
I have double-checked the settings for speed and duplex.
The version of BE used is 10.1 Rev 5629.
All Remote Agents have been updated.
There is only 2 differences in this scenario that I am aware of:
a) FTP protocol vs. ndmp
b) NTFS vs. Backup Exec´s backup-to-disk device
If disk fragmentation is the problem, it would also affect FTP-transfers.
Is it possible to configure backup-to-disk devices block and buffer size ?
