Our TSM server is version 5.1.7.3 on AIX 5.1.
The TSM client on an sun solaris server was 5.1.5.14. We got 
the following summary on an incremental backup:
 
Total number of objects inspected:  107,330
Total number of objects backed up:      414
Total number of objects updated:          0
Total number of objects rebound:          0
Total number of objects deleted:          0
Total number of objects expired:        371
Total number of objects failed:           0
Total number of bytes transferred: 237.13 MB
Data transfer time:                   21.52 sec
Network data transfer rate:        11,280.08 KB/sec
Aggregate data transfer rate:        683.02 KB/sec
Objects compressed by:                    0%
Elapsed processing time:           00:05:55
 
Then we make an upgrade to TSM client 5.2.2.0. We doesn´t 
change any parameter and get the following result.
 
Total number of objects inspected:  107,332
Total number of objects backed up:      428
Total number of objects updated:          0
Total number of objects rebound:          0
Total number of objects deleted:          0
Total number of objects expired:        371
Total number of objects failed:           0
Total number of bytes transferred:    265.83 MB
Data transfer time:                   35.32 sec
Network data transfer rate:        7,705.93 KB/sec
Aggregate data transfer rate:        190.49 KB/sec
Objects compressed by:                    0%
Elapsed processing time:           00:23:48
 
The duration of the backup is now much greater than before. 
Any explanation for this behavior?
 
Thanks
