Hey, I have been looking for a good way to backup my Ubuntu system for ages. There seem to be no good programs in our repositories or I am blind.
So I decided to write a beauifull little script. It started out as a simple task and just kept getting bigger and better. It was based off of various scripts I found on the Google.
Features:
- Will scan home directorys and exclude files larger than 10meg (You can change this variable)
- Reads ".exclude" files from home directories for manual exclusions.
- Reads ".exclude" files from any of the other specified inclusions for exclusion.
- Creates archives with date tags
- Easily editable variables
- Verifies backup integrity
Code:
#!/bin/bash
# Backup Script by Jesse Harris
# Create backups of /etc, /home, /usr/local, and...
PATH=/bin:/usr/bin
#######################################################################
# Please edit these variables to match your system #
# #
# backupdirs - This specifies seperate archives you wish to create #
# - You can put a .exclude file into these directories #
# - for manual exclusions (Specify the full path) #
# dir - This is where you backups will be stored, if it is #
# - within your inclusion path, make sure to put it into #
# - its relevant .exclude file. #
# homes - This is a temp file created whenever the script is run #
# sizecheck - This specifies that home directories are to be scanned #
# - for file sizes, do not change this variable #
# maxsize - This specifies that anything exceeding this size within#
# - anyones home directory will be automatically excluded #
#-----------------------------Good Luck-------------------------------#

backupdirs="/etc /root /home /boot /var /bin /initrd /lib /sbin /usr"
dm=`date +%d%b`
dir="/home/harrisj/backup/"
homes="/tmp/homes"
sizecheck="/home"
maxsize="+10M"
# Check if root
if [ "$(whoami)" != "root" ]; then
echo "Not running as root. Exiting..."
exit 0
else
echo "Running as root. Good"
fi
mkdir -p $dir$dm
for path in $backupdirs
do
if [ "$path" = "$sizecheck" ]; then
ls $path > $homes
for home in $(cat $homes)
do
if [ "$home" != "$sizecheck" ]; then
echo "Checking $home Filesizes..."
find $path/$home/ -size $maxsize -type f -print > $path/$home/auto-exclude
echo "System backup on $path/$home"
tar --exclude-from=$path/$home/auto-exclude --exclude-from=$path/$home/.exclude -czf $dir$dm/$home.tar.gz $path/$home 2>/dev/null
fi
done
else
if [ -e $path/.exclude ]; then
echo "Reading exclude file.. for $path"
echo "System backup on $path"
tar --exclude-from=$path/.exclude -czf $dir$dm/$path.tar.gz $path 2>>/dev/null
else
echo "System backup on $path"
tar czf $dir$dm/$path.tar.gz $path 2>>/dev/null
fi
fi
sleep 2
done
echo "System backups complete, status: $?"
echo "Now verifying system backups"
for path in $backupdirs
do
echo "Verifying $path...."
if [ "$path" = "/home" ]; then
for home in $(cat $homes)
do
zcat $dir$dm/$home.tar.gz | tar t 2>/dev/null && \
if [ $? -eq 0 ]
then echo "$path: verified"
else echo "$path: error(s) in verify" | wall
fi
done
else
zcat $dir$dm/$path.tar.gz | tar t 2>/dev/null && \
if [ $? -eq 0 ]
then echo "$path: verified"
else echo "$path: error(s) in verify" | wall
fi
fi
done
echo "Please remove backup tape" | wall
Example .exclude file from /home/harrisj/.exclude
Always specify the full path in your .exclude files
Code:
/home/harrisj/backup/*
/home/harrisj/c/*
/home/harrisj/dvdrip/*
/home/harrisj/Qemu/*
/home/harrisj/iso/*
/home/harrisj/Games/*
/home/harrisj/Temp/*
/home/harrisj/Video/*
/home/harrisj/vcr/*
/home/harrisj/.Trash
/home/harrisj/.transgaming/*
~/music
~/roms
~/winetools
Also, its handy to have a nautilus script to easily add directories to your home .exclude file
vi ~/.gnome2/nautilus-scripts/Add\ To\ Backup\ Exclude
Code:
base="`echo $NAUTILUS_SCRIPT_CURRENT_URI | cut -d'/' -f3- | sed 's/%20/ /g'`"
if [ -z "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" ]; then
dir="$base"
else
while [ ! -z "$1" -a ! -d "$base/$1" ]; do shift; done
dir="$base/$1"
fi
echo $dir >> ~/.exclude
chmod ug+x ~/.gnome2/nautilus-scripts/Add\ To\ Backup\ Exclude
Now just right click on the directory-->Scripts-->Add to backup exclude.
Good bye
Edit: Bugfix
Edit: Script update
Edit: missed a slash in there.
Edit: Changed a line of code that was wrong.
