This is my Monthly backup cron.

What this does is optimize all the images in the public_html folder, zips it then sends a copy of public_html to Dropbox.

What you need to do for the script to fully work.

First thing is to install jpegoptim & OptiPNG.

You do this by running:

Code:
sudo apt-get install jpegoptim optipng

Next thing to do is to set up Dropbox.

Code:
wget -O dropbox_uploader.sh https://raw.githubusercontent.com/andreafabrizi/Dropbox-Uploader/master/dropbox_uploader.sh
chmod a+rx dropbox_uploader.sh
sudo mv dropbox_uploader.sh /usr/local/bin/dropbox_uploader
sudo chown root:root /usr/local/bin/dropbox_uploader
dropbox_uploader

Follow the on prompt commands because you will need to create a Dropbox API.

Code:
nano /etc/cron.monthly/backup

Code:
#!/bin/bash
cd /var/sentora/hostdata/zadmin/public_html/
find -iregex '.*\.\(png\)$' -print0 | xargs -0 optipng -o7 -preserve
find -iregex '.*\.\(jpg\|jpeg\)$' -print0 | xargs -0 jpegoptim --max=90 --strip-all –all-progressive --preserve --totals
find -iregex '.*\.\(jpg\|png\|jpeg\)$' -exec chmod 644 {} \;
find -iregex '.*\.\(jpg\|png\|jpeg\)$' -exec chown www-data:www-data {} \;
rm -rf /var/sentora/hostdata/zadmin/backup.zip
cd /var/sentora/hostdata/zadmin/
zip -r backup.zip public_html
dropbox_uploader delete /backup.zip
dropbox_uploader upload /var/sentora/hostdata/zadmin/backup.zip /backup.zip
exit 0

F3 will save the file and Ctrl+X will exit nano.

Next set the correct permissions.

Code:
sudo chmod +x '/etc/cron.monthly/backup'
sudo chmod 755 '/etc/cron.monthly/backup'

This is my Weekly updater cron.

What this does is run the system updater and installs any new updates. If an update requires a reboot, the script will reboot the server.

The script will also backup the logs and run a fsck to repair the disk if the system gets rebooted.

What you need to do for the script to fully work.

Edit fsck so it forces the fix.

Code:
nano /etc/default/rcS

Change the line at the end of that file to:

Code:
FSCKFIX=yes

from:

Code:
#FSCKFIX=no

F3 will save the file and Ctrl+X will exit nano.

Code:
nano /etc/cron.weekly/updater

Code:
#!/bin/bash
/usr/bin/dpkg --configure -a
/usr/bin/apt-get update
/usr/bin/apt-get -qy dist-upgrade
/usr/bin/apt-get install -f
/usr/bin/apt-get clean
/usr/bin/apt-get -qy autoremove

#Backup Logs
rm -rf /var/sentora/hostdata/zadmin/logs.zip
cd /var/
zip -r /var/sentora/hostdata/zadmin/logs.zip log
dropbox_uploader delete /logs.zip
dropbox_uploader upload /var/sentora/hostdata/zadmin/logs.zip /logs.zip

#Clean Logs
find /var/log -type f -delete
touch /var/log/dovecot.log
touch /var/log/dovecot-info.log
touch /var/log/dovecot-debug.log
chown vmail.mail /var/log/dovecot*
chown mysql:mysql /var/log/mysql*
service dovecot restart

if [ -f /var/run/reboot-required ]; then
sudo touch /forcefsck
sudo reboot
else
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge
exit 0
fi

F3 will save the file and Ctrl+X will exit nano.

Next set the correct permissions.

Code:
sudo chmod +x '/etc/cron.weekly/updater'
sudo chmod 755 '/etc/cron.weekly/updater'

This is my Daily database cron.

What this does is optimize all the the databases and backs them up to Dropbox.

Code:
nano /etc/cron.daily/database

Code:
#!/bin/bash
mkdir -p /var/sentora/hostdata/zadmin/database
mysql -u root -p*PASSWORD* -e "FLUSH TABLES WITH READ LOCK;"
mysqlcheck --auto-repair -Aos -u root -p*PASSWORD*
mysqldump -u *USER* -p*PASSWORD* *DATABASE_NAME* > /var/sentora/hostdata/zadmin/database/*DATABASE_SAVE*.sql
*Repeat the above line for each database*
mysql -u root -p*PASSWORD* -e "UNLOCK TABLES;"
rm -rf /var/sentora/hostdata/zadmin/database.zip
cd /var/sentora/hostdata/zadmin/
zip -r database.zip database
rm -rf /var/sentora/hostdata/zadmin/database
dropbox_uploader delete /database.zip
dropbox_uploader upload /var/sentora/hostdata/zadmin/database.zip /database.zip
exit 0

Key:

*PASSWORD* = DB/MySQL Root Password.
*USER* = DB user.
*DATABASE_NAME* = Name of the DB.
*DATABASE_SAVE* = What you want to call the saved DB.

F3 will save the file and Ctrl+X will exit nano.

Next set the correct permissions.

Code:
sudo chmod +x '/etc/cron.daily/database'
sudo chmod 755 '/etc/cron.daily/database'
