All the terms a relative to how often you perform backups.

If you perform a backup once a day and need to go back 45 days, and the file 
could be change every day, you need to set all parameters to 45.

That is retain changed version for 45 days if the file still exists
Retain the 45 version of the file even if the file is deleted.
Retain extra version 45 days.
Retain the only version for 45 days.

Now if you perform a backup more than once a day the files can theoretically be 
changed ever time a back up is run and you would have to adjust accordingly. 
Also if you are performing a backup less often than once a day the number of 
versions may keep much more data than you want.
