A bash script is more or less only a sequence of the commands you can run 
on the command line. Therefore your filename would be made like you wrote 
above. Then you have to redirect the output of your commands inside the 
script to that file. That would be something like this:

log=$(date "+backup.log.%d%m%y")
echo "Starting backup $(date)"
somecommand >>$log 2>&1
anothercommand >>$log 2>&1
echo "Backup finished $(date)" >>$log

Both the output and error output of the commands are sent to the same log
