Question : .htaccess Redirect Folder BUT Keeping Additional Strings / Variables?

I have the following htaccess redirect:

RewriteRule ^folder/([^/]*)/ folder/index.php?a=$1 [L]

This basically redirects:
mysite.com/folder/10/

To:
mysite.com/folder/?a=10

The problem is that I also require additional variables that I do not know, E.g.
mysite.com/folder/10/?a=fff&b=eee&c=ddd

Is there a way to keep these variables within the redirect even though I do not know what they are going to be?

Finally found the answer:

Under Backup
Filesystem
Select one of the backups and then change the dropdown from Filesystem Backups to Network Share Backup.  Click Map Network Share and select a server that has the client installed and will have rights to the NAS.  Then type the UNC into the Share Name leaving connect as blank.  Hit apply and then close.  You should now be able to select what you want backed up.
