Logger itself works fine, including in the function.

I think you want it.
Code:
cat /etc/rsyslog.d/mugsyback.conf 
# - mugsyback logging -
local1.notice                   /var/log/mugsyback.log
local9.debug			/dev/null

and
Code:
sysLogger () {
        local logPriority=$1
        local logMessage=$2
        case "${logPriority}" in

                critical)       logger -p local1.notice -t mugsyback.crit ${logMessage}
                ;;  
                warning)        logger -p local1.notice -t mugsyback.warn ${logMessage}
                ;;  
                info)           logger -p local1.notice -t mugsyback.info ${logMessage}
                ;;  
                debug)          if "${logLevel}" = "debug" ; then
                                        logger -p local1.notice -t mugsyback.debug ${logMessage}
                                        else 
                                        logger -p local9.notice -t mugsyback.debug ${logMessage}
                                fi  
                ;;  
                *)              echo "logging option does not exist"
                ;;  
        esac
}

Nice work!

I simply hadn't thought of using syslog itself to send it to /dev/null.

That will work fine for my script.

Thankyou very much for taking the time to respond John1212, this is what I ended up using as a test:

Code:
$ cat /tmp/mugsyback.test
#!/bin/bash

logLevel=

####### logging
sysLogger () {
        local logPriority=$1
        local logMessage=$2
        case "${logPriority}" in

                critical)       logger -p local1.notice -t mugsyback.crit ${logMessage}
                ;;  
                warning)        logger -p local1.notice -t mugsyback.warn ${logMessage}
                ;;  
                info)           logger -p local1.notice -t mugsyback.info ${logMessage}
                ;;  
                debug)          if test "${logLevel}" = "debug" ;
					then
                                        	logger -p local1.notice -t mugsyback.debug ${logMessage}
                                        else	
						logger -p local1.debug -t mugsyback.debug ${logMessage}
                                fi  
                ;;  
                *)              echo "logging option does not exist"
                ;;  
        esac
}

mount -v /mnt/backup 2> >(sysLogger "critical") 1> >(sysLogger "debug") || { echo "failed" ; exit 1 ; }

And for syslog:

Code:
$ cat /etc/rsyslog.d/mugsyback.conf 
# - mugsyback logging -
# log all debug messages to /dev/null unless debugging enabled
# log everything else to /var/log/mugsyback.log
local1.notice	/var/log/mugsyback.log
local1.debug	/dev/null

I still get the file descriptor errors though so that's what I need to figure out next. Here is what the debug looks like now and shows at what stage the file descriptor errors occur (I haven't tidied up the logging yet)...
