I am taking the backups by using the following files:

Parameter file

Userid = 'test/test@test'
File = d:\testbackup\exp_test.dmp
Log = d:\testbackup\exp_test.log

Batch File

exp parfile=d:\testbackup\test.par

I have automated the task using the Windows scheduler.

When ever i take the backups it overwrites the previous backup file.

Now can i modify my script so that i can include date in the filenames.

Also can i keep the backup for say 3 days and then delete the same modifying the script.

I am using Windows 2000 Advanced Server and Oracle 9i.

Any suggestions for the same.
