To change interval

http://guides.diditbetter.com/a2e-guide/index.html

You can change the public folder name if you wish

this physical naming does not affect A2E

However, the location does matter to A2E

If you are going to change the location

The free way is to remove the relationships and remove destination copies

And then sync

Then remake the relationships

To license and run the Recovery and Migration Manager tool -- this options includes 4 hours of Premier Support:  Buy Now

And it will reattach the relationships in place without doing the removal and rebuild.

hope this helps.  Cheers!
