For everyone's review and comment...  :^)   I haven't yet tested
whether this remote backup backup is really useable...

First, I set up a fairly normal user "rsync1" on both boxes, and did
the normal ssh keys setup so I didn't need passwords.  

As rsync1 on the primary store, I have the following slightly redacted
crontab and script:

rsync1 at brick:~$ crontab -e
# m h  dom mon dow   command
6 */4 * * * /home/rsync1/cron/rsync-ts4-backups
MAILTO=supportx at tebucosafe-junk.com


rsync1 at brick:~$ cat /home/rsync1/cron/rsync-ts4-backups
#if [[ `ps -ef | grep rsync1-ts4-rsync | grep -v "grep
rsync1-ts4-rsync" |  wc -l` -lt 1 ]]
#First fix the accounts, just in case, per Ben Summers.
#Oops, can't do it because rsync1 is not in sudoers list.
#   Set it to run hourly as some sudoer's cron job
#for x in ` cat /usr/local/bin/accountlist | cut  -f1 ` ; do sudo
bbstoreaccounts check ${x} fix ; done
#Now backup the backup to a remote server
#some tracking info...
date ; id ; uname -a ; pwd
#make sure it's not running already or still...
if [[ `ps -ef | grep "/usr/bin/rsync.*host.myoffsitebackupdomain.com" |
grep -v grep > /dev/null ; echo $? ` -ne "0" ]]
  #     LPATH needs trailing slash

  #   --bwlimit=KBPS          limit I/O bandwidth; KBytes per second

  #$RSYNC -azvu --delete --stats  -e "$SSH -o StrictHostKeyChecking=no
  #Main one:
  $RSYNC -azvu --delete --stats --bwlimit=60 --exclude=write.lock -e
"$SSH -o StrictHostKeyChecking=no -p 2222 -i $KEY" $LPATH
  #No verbose:
  #$RSYNC -azu --delete --stats --bwlimit=60 -e "$SSH -o
StrictHostKeyChecking=no -p 99999 -i $KEY" $LPATH $RUSER@$RHOST:$RPATH
  # No bwlimit:
  #$RSYNC -azvu --delete --stats -e "$SSH -o StrictHostKeyChecking=no
#how long did it take...
rsync1 at brick:~$
