'Not intending to hijack this thread, but I decided it would not hurt to post my rsync BASH file for people to see and use as they see fit:
The /etc/gadmin-rsync/inhibit file needs to contain some text. If it contains the text "CRC", then the rsync process will do a full checksum on all the files. Any other text in the file will prevent the checksum.
Bash:
#!/bin/bash
RunFile=/var/run/gadmin-rsync-Main.run # Run file to prevent multiple instances of the script running
LogFile=/var/log/gadmin-rsync/gadmin-rsync-Main.log # Log file to keep track of backup sessions and / or failures
grep -iq true /etc/gadmin-rsync/inhibit && exit 0 # Check to make sure CRC is properly set or unset
CRC=""
grep -iq crc /etc/gadmin-rsync/inhibit && CRC=--checksum # Check to see if checksum is required (takes much, much longer)
thisPID=$$
START_TIME=`date +%Y-%m-%d_%H:%M:%S`;
noMount=1
Running=1
mount | grep -q /Backup && noMount=0 # Check to see the RAID array is mounted
if [[ -s $RunFile ]]; # Sanity check
then
ps -fp $( cat $RunFile ) > /dev/null
if [ $? -eq 0 ]
then
Running=0
else
echo $thisPID > $RunFile
fi
