Morning John, backing up to an external hard drive is something I have been doing for years.
I just wanted to know how to back up the route I've been working on and where to find it if I needed to re-install TS2010.
Sorry to be fussy, but my name is Craig not Sam, that's my dogs name. (I'll send a ticket to the help desk to see if my name can be changed to Craig72).
A big thank you to everyone for their help.
Craig.
		
		
	 
Sorry, Craig. I went by your username. It looks like your name is changed to Craig now, which will solve that problem! 
 
Very simply, back up your route to a CDP file.
In Content Manager, go to the tab called My Content.
You'll see your routes, consists, and sessions listed.
Sort by name to get everything alphanumeric.
Click on the route and press CTRL to select the session.
Right-click on these selected items, and choose Save to CDP...
Specify the path, and type the name. I give my stuff version numbers and a date. You can do whatever suits you.
Click OK and let the program do its thing. The bar will move across. I like to view details so I can see that everything was saved to the CDP properly.
When this is done, you can then copy the backed up route files to your backup drive.
Hope this helps.
John
