Hi,
The backup will take a very Long time the first time you start it. Once the FIRST backup is finished, the second will run really fast and so on.
First backup = complete Image, after that the backups are incremental, thats why they are faster.
you can use wbsadmin in the DOS box to check and Change your backup schedules and Counts if necessary.
leave it running until it has finished.
