Create Incremental Backup Script Using rsync

[Keetawat]

Dear All,
Can you please show or explain me for how to create daily incremental backup script by using the rsync.
Here is my script

#!/bin/sh
#Created By Keetawat Chaichompoo.
# emails a status report
(
echo "To: EMAIL_RECIPIENTS"
echo "Subject: SUBJECT"
echo " "
) > /var/mail_rsync
echo " " >> /var/mail_rsync
LastFolder=`cat /SCRIPT_FOLDER/last_folder.txt`
YesterdayDate=`date -v -1d +%F`
#TodayDate=`date +%F`
TodayDate=`date +%F%H%M%S`
Source="PATH_OF_SOURCE_FILE_FOLDER"
Destination="PATH_OF_DESTINATION_BACKUP/$TodayDate"
DestinationLink="PATH_OF_RECENT_FOLDER/$LastFolder"
Options="-avrh --delete --ignore-errors --compare-dest=$DestinationLink --exclude-from SCRIPT_FOLDER/exclude_list.txt"
echo "###Start Rsync Activity $(date)##" >> /var/mail_rsync
echo "Source : $Source" >> /var/mail_rsync
echo "Target : $Destination" >> /var/mail_rsync
echo "Executing : rsync $Options $Source $Destination" >> /var/mail_rsync
rsync $Options $Source $Destination >> /var/mail_rsync
echo "###Finished Rsync Activity $(date)###" >> /var/mail_rsync
sendmail -t < /var/mail_rsync
CountLine=`cat /var/mail_rsync|wc -l`
if [ $CountLine -eq 14 ];
then
#echo "Nothing"
else
echo $TodayDate > SCRIPT_FOLDER/last_folder.txt
fi
exit 0

For any of suggestions are welcome.
Thank you in advance.

Dear All,

Most people on this forum would recommend using the built-in ZFS mechanisms for snapshots.

That said, if you're set on using rsync, I would look into rsnapshot rather than re-inventing the wheel with your script:
