How do incremental backups work in Photoshop Elements?

Question

I'm trying to figure out INCREMENTAL backups in Photoshop Elements.  I've performed an INITIAL backup on a Seagate Backup Plus external drive.  Now when I try to perform an INCREMENTAL backup to the same folder, I get this warning:  "! A backup already exists in that folder, do you want to overwrite it?"  When I say no, it won't let me save the INCREMENTAL back up in the same folder.  Is "yes" the correct answer?  If so, please explain how this works.  I want to make sure I don't lose anything in the initial backup.

Once you have a full backup you can make incremental backups in future which will be much quicker.
Don’t use the same folder, make a new one. Once you have a full back up you can make incremental back ups but you need to follow a set routine. It’s not very intuitive.
Start by creating a new folder or label a new CD/DVD Disk - it’s best to use dates e.g. “PSE12 incr backup 2014-June-04”
Press Ctrl+B and check Incremental, then click Next
Highlight your drive containing the last backup and click the bottom Browse button (previous back up file) then navigate to the TLY file and click open.
Click the Browse button above and navigate to your new folder “PSE12 inc backup 2014-June-04”
Click Done.
If your full backup originally contained 500 images, the incremental backup will only contain changes since the last backup e.g. files B000501.jpg, B000502.jpg etc
If you ever have to do a complete restore you start with the TLY file from the latest incremental backup. The program automatically recognizes the number of incremental steps and you will be prompted to insert a disc or navigate to the appropriate drive/folder.
Incremental backup’s are obviously much quicker to write to disk but I recommend that you periodically perform another full backup and delete any earlier backups.
