Well I did a little more testing.
First - all 6 office PCs now have Gbit network connections and are linked through an 8 port Gbit switch for local traffic.
I did a test doing an Acronis Backup and verifiy operation of ONE PC to another PC which serves as storage (it is used as a desktop as well). The Network Utilization in Task Manager varied from 40%-60% of the Link Speed of 1Gbit. The backup went QUICKLY.
I then did a test with TWO PCs doing an Acronis Backup simultaneously to the SAME PC serving as storage. The Network Utilization in Task Manager dropped to ~4%-6% of the Link Speed of 1GB.
I can understand the transfer speeds dropping when more than one backup is occuring simultaneously. But decreasing to 10% of a single backup occuring?
What am I missing here? The choke point would be the target storage PC but dropping to 10% when more than one backup is occuring? Is there a configuration setting that needs to be adjusted? Any advise would be appreciated.
