Figure 16-14 Backup status window
As you can see in Figure 16-14, the positive LanFree Data Bytes value confirms
that the backup was done via SAN. The difference between the Bytes
Transferred and LanFree data Bytes value is because the LAN path is used for
storing metadata in the server database, and thus the total value for transferred
data will always be slightly greater than the LanFree Bytes value.
In Example 16-28 we show statistics as produced by the command-line
backup-archive client for another incremental backup operation. Again, you can
easily distinguish how much data was transferred via SAN from the
LanFree data
bytes
statistic value.
