I personally have changed the backup files to only have a prefix "~BAK~" and 
no suffix so that the file index.php would be ~BAK~index.php.
This way it does not matter if a file is uploaded as Apache hands it off to 
the PHP engine to handle.  

It is still best not to upload a backup file as it may contain errors and 
error messages that dump information it should not, however it is less likely 
to be found and it is not full code disclosure if you use a prefix rather 
then a suffix.

The only down-side is that the files are sorted differently... ie all the 
backup files are at the top of the list of files in a directory, rather then 
with the original.

To change this setting:
Settings->Configure Editor->Open/Save->Backup on Save: Prefix and Suffix.

To remove all backup files from a directory (and subdirectories) run this bash 
script:

	for BACKFILE in `find -name ~BAK~*`
	do
		rm ${BACKFILE}
	done

where ~BAK~ is the prefix you use...
The first line does a find all files that start with the prefix and loops 
through each one assigning the name of the file to the variable BACKFILE as a 
string
each loop we remove the file referred to in the string ${BACKFILE}
BASH scripting is fun in that you assign a variable without a $ but to use one 
you must put the $. The braces {} can help with some problems (strings with 
spaces? but I cannot remember)  so I always use them.

The best place to look for BASH scripting help is the Advanced Bash-Scripting 
Guide at:

I hope I have been clear if not ask me for more info. (And I hope I am not too 
off topic
