I would not make any changes because of the smartclt reports.

Without seeing the exact command issued, it would be hard to figure out. 
  But, I do use the -x (--one-file-system) option when invoking rsync(1) 
to prevent trying to backup network mounts (see below).

I keep my system images small enough to fit on 16 GB devices -- USB 
flash drives, SSD's, HDD's, whatever.  My backup strategy is many-fold:

1.  I wrote a script that calls dd(1) to copy the raw contents to a 
tar(1) gzip(1) file.  I run it from a USB flash drive with Debian 
installed on it.  The script also generates MD5 and SHA256 checksum 
files, and can reverse the process.  I call this "imaging".

2.  Whenever I create or modify a system configuration file (e.g. 
/etc/*), I check-in the file to CVS.  I call this "configuration 
management".

3.  I wrote a script that invokes rsync(1) to copy my system drives to 
backup directories on my SOHO server.  I call this "backup".  Here is 
the rsync(1) command issued by the script to backup the system drive in 
my Debian daily driver.  I have replaced the spaces with newlines to 
avoid e-mail wrapping:

+ /usr/local/bin/rsync
  -a
  --delete
  -e /usr/bin/ssh
  -x
  root@tinkywinky.tracy.holgerdanske.com:/
  /var/local/backup/tinkywinky.tracy.holgerdanske.com//

Your rsync(1) command has a lot more switches.  I am not going to try to 
figure them out.  I prefer to KISS and use the bare minimum.

4.  The server data is on ZFS.  I wrote another script to snapshot and 
replicate the ZFS filesystems to other pools -- one on-site, one 
near-site, and one off-site.  The on-site pool is a mirror is inside 
another server, but the near-site and off-site drives are in mobile dock 
drawers; I rotate them bi-monthly.  I call this "redundant backups".
