There is also the 'chitchat' that the client and server do when discussing
whether an individual file has been backed up or is missing. That increases
the network transmissions significantly if you have a large number of files and
are not using local journaling.

Subject: [ADSM-L] Backup larger than data on server
We have TSM version 5.2. The client server I am referring to here is
Redhat linux.
In the /var/log/tsm/dsmsched.log it lists
Total number of bytes transferred: 79.18 GB
However there is only around 60 Gb of data on the server (see df below)
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.7G 2.1G 7.1G 23% /
/dev/sdb2 104G 57G 43G 58% /opt
Can someone explain why the number of bytes transferred exceeds the
amount of data on the server?
Thanks
Paul
