Rerun Rsync After Unsuccessful Connection in Cron - linux

Question

I have a bash script in my cron that has a passwordless rsync command to pass files from my local system to a web server.
Bash Script Code:
rsync -avzhe "ssh -p2222" ---chmod=Du=rw,Dg=r,Do=r,Fu=rw,Fg=r,Fo=r -p /home/sysadmin/some_file_{0..10}.png username#web.server:public_html/some.directory/
Over the past few days, I have noticed that the connection is randomly refused sometimes. I have correctly set up openssh-client and openssh-server and have set up the password ssh login successfully so, I'm not sure what is causing the connection to randomly be refused sometimes.
Now, I am looking for some code to force the rsync code to rerun until the files are successfully passed to the web.
Rsync Code:
RC=1
while [[ $RC -ne 0 ]]
do
rsync -avzhe "ssh -p2222" ---chmod=Du=rw,Dg=r,Do=r,Fu=rw,Fg=r,Fo=r -p /home/sysadmin/some_file_{0..10}.png username#web.server:public_html/some.directory/
RC=$?
done
Is this the best method to try and circumvent the issue?

You don't need to store the return code of rsync, just do a loop like
#!/bin/bash
until rsync -avzhe "ssh -p2222" ---chmod=Du=rw,Dg=r,Do=r,Fu=rw,Fg=r,Fo=r -p /home/sysadmin/some_file_{0..10}.png username#web.server:public_html/some.directory/; do
sleep 5 # waiting for 5 seconds before re-starting the command.
done
