backup from a W2003-Server is very slow, when I use a scheduled backup. Backup via CLI works with normaly and high speed ( and over batchfile ).
What is the reason ?
Without details, we can only generally advise you on this... The two obvious differences would be time of day (where you probably tried the comparative CLI type backup during the day, whereas scheduled backups probably run overnight) and that scheduled backups include PRESchedulecmd and POSTSchedulecmd involvement. Time of day may make a big difference in what else is running in that system, which can at times make for a lot of contention for file access, as seen in backup log Retries. It may also be that certain sets of files see updating at a certain time of day, where they would be backup candidates only then. Compare the contents of your two backup logs. The configuration of your TSM server is also a substantial factor, where over-demand for tape drives at peak period can cause some clients to wait for resources, for example.
Beyond that, see the "Backup performance" topic in http://people.bu.edu/rbs/ADSM.QuickFacts for factors we have communally experienced. If you still need input, post again, providing salient details (hardware info, service pack level, TSM software levels, particulars from the backups, etc.
