Change destination folder

Hope someone can help me out here please
Currently set my full backup’s to run daily (previous experience has made me do this) and it is this I am having a problem with in as much as the destination is in my case “Backup Drive (H:)”, and I want my backup’s to go to a folder within that drive
Is there any way that I can change the destination to “H;\My Backups\Master Backups”?
Thanks

Hello,

What’s the model number of the unit?

What backup software are you using?

Not sure why you need that, but I have a Western Digital My Book 1230 connected by USB
It is working fine doing the backups just want to change the destination
Thanks
