Actually the LASTSESS_SENT field is for data sent for *any* TSM client
operation, not just for the last backup. So if between the time the backup
finished and the SELECT statement is run, the user performs some other
operation... even something like DSMC QUERY SESSION... then the
LASTSESS_SENT field will reflect data from that operation, not the last
backup. Thus I would not recommend using this, as it is not entirely
reliable for this purpose.
For example:
DSMC INCREMENTAL
LASTSESS_SENT reflects data sent during incremental backup
DSMC SELECTIVE C:\MYFILE.TXT
LASTSESS_SENT reflects data sent during backup of c:\myfile.txt
DSMC QUERY SESSION
LASTSESS_SENT reflects data sent (very small amount) for QUERY SESSION
SELECT NODE_NAME, LASTSESS_SENT FROM NODES
Output reflects value from the above QUERY SESSION command.
As this sequence shows, you could get misleading information using this
method.

Run this query command and it will give you the node name and how much data
that node sent from it's last backup.
select NODE_NAME,LASTSESS_SENT from nodes
