Top Forums Shell Programming and Scripting Help with Backup Shell Script Post 302555673 by Creepy on Thursday 15th of September 2011 09:43:23 AM
I'm very new to Linux, but here are two I made that might give you some ideas. The first is the Backup script I use for MYSQL, and the script below it cleans up old backups. It is the first script I wrote myself. I should really update them since I have leaned so much since then on what is wrong with these, but they have worked flawlessly for me.

I hope they might help.

Code:
#!/bin/bash 
#Backup Script for a Server
#
# First Create 2 folders "/usr/local/bin/backup/" and 
# "/usr/local/bin/tar"
#
NOWDATE=NAME OF ARCHIVE-`date +%d%m%y`.tgz 
BACKUPDIR=/usr/local/bin/backup/ 
BACKUPTAR=/usr/local/bin/tar 
MOUNTLOC=//X.X.X.X/path/to/mount/
USERNAME=username=xxx 
PASSWORD=password=xxx

# This tells MYSQL to dump all of it's databases to the $BACKUPDIR 
# directory.
mysqldump -u xxxxx -pxxxxxx --all-databases > $BACKUPDIR/xxxx.sql

#This copies all files/directories to the BACKUPDIR.
cp -r /whatever/you/want /usr/local/bin/backup

#This uses tar with compression to put it all in one file.
tar pcfz $BACKUPTAR/$NOWDATE $BACKUPDIR

#This mounts the SAN drive.
mount -t smbfs $MOUNTLOC /mnt -o $USERNAME,$PASSWORD

#This copies the contents of the BACKUP tar files to the SAN.
cp $BACKUPTAR/* /mnt

#This emails a log of what was backed up.
ls -trlh /mnt | tail -1 | mail -s "Server Backup Results" someguy@domain.com

#This unmounts the mounted SAN drive.
umount /mnt

#This removes all files from the BACKUPDIR.
rm -rf $BACKUPDIR/*

#This removes all files from the BACKUPTAR
rm $BACKUPTAR/*

exit 0


-------------------------------------------
To clean up the destination directory I use this:

Code:
#!/bin/bash
#  Script to tidy up Backups older than 2 days after they went to tape.

MOUNTDIR=//X.X.X.X/Path/to/Backup/Dir
EMAIL=someguy@domain.com
USERNAME=username=xxx
PASSWORD=password=xxx

#This mounts the S drive folder.
mount -t smbfs $MOUNTDIR /mnt -o $USERNAME,$PASSWORD

#Find files older than 2 days.
find /mnt -mtime +1 | mail -s "Backups Deleted" $EMAIL

# This command finds and deletes files older than 2 days and emails me.
find /mnt -mtime +1 -exec rm -f {} \;

#This unmounts the mounted S drive.
umount /mnt
