Figure 1 – Network Layout: Backup of 4 Servers Across 4 Dedicated 10Base-T Segments
At the storage server, four tape drive “groups” are set-up under ARCserve, one for each server to be
backed up.
Each drive group contains only a single 15/30-GB DLT drive, for it has already been
shown that there is no performance benefit with more than one DLT per 10 Mbit segment.
With this
setup, backup jobs were initiated simultaneously on from 2 to 4 database servers.
The following chart
shows the throughput results as well as the CPU usage on the tape server.
The network % figure shown
is an average of the usage seen on each of the segments involved in the respective backup runs.
