[ubuntu-uk] Simple backup script

[Chris Rowson]

Thanks so much for all of your suggestions guys.

I ended up with something like this which resulted in part from a need to
get my backups onto a Windows Server and to get an email when it happens (or
if it doesn't).


#!/bin/bash
BACKUPDIR="/home/USERNAME/backup"
WHATTOBACKUP="/var/www"
SERVERNAME="SERVERNAME"
BACKUPADMIN="EMAIL at DOMAIN.COM"
MESSAGE="/tmp/message.txt"

if [ -d $BACKUPDIR -a -d $WHATTOBACKUP ] #make sure the source & dest dirs
exist
then
       #backup the directory
       /bin/tar -cpzf $BACKUPDIR/`date +%a"-"%d"-"%b"-"%Y"-"`backup.tar.gz
$WHATTOBACKUP
       #then remove anything over 7 days old
       find $BACKUPDIR/*.tar.gz -mtime +7 -exec rm -f {} \;
       #And let us know what happened
       SUBJECT="Backup Completed"
       TO=$BACKUPADMIN
       echo "Backup of $SERVERNAME completed" >> $MESSAGE
       echo "Result of backup" >> $MESSAGE
       echo "`ls -alt` $BACKUPDIR" >> $MESSAGE
       /usr/bin/mail -s "$SUBJECT" "$TO" < $MESSAGE
       rm $MESSAGE
else
       #if backup dir does not exist, tell us
       SUBJECT="Backup Failure"
       TO=$BACKUPADMIN
       echo "Error backing up $SERVERNAME" >> $MESSAGE
       echo "One of the following directories is missing: $BACKUPDIR
$WHATTOBACKUP " >> $MESSAGE
       echo "Date: `date`" >> $MESSAGE
       /usr/bin/mail -s "$SUBJECT" "$TO" < $MESSAGE
       rm $MESSAGE
fi
