Backup File Bash Script

I'm trying to create a bash script to backup the databases for three sites. It got a little involved, so I thought I would throw it up here to make sure I have it setup correct. Here is what I have:

---

Create / Add the Backup Script

Code:

nano /root/tools/backup-databases.sh

Bash Script

Code:

#!/bin/bash
#Purpose = Database Backups
TIME=`date +%b-%d-%y`
# MYSQL User which will probably be root
MYSQLUSER=user
# MYSQL Databases on server
MYSQLDBASE1=databasename1
MYSQLDBASE2=databasename2
MYSQLDBASE3=databasename3
# MYSQL Database Filenames
FILENAME1=$MYSQLDBASE1-$TIME-backup.sql
FILENAME2=$MYSQLDBASE2-$TIME-backup.sql
FILENAME3=$MYSQLDBASE3-$TIME-backup.sql
# Directories
DESDIR=/root/backups/databases
# Time based backup directory
DBASEBACKUPNAME=databasesBackup-$TIME
# Make time based directory to hold sql files
mkdir /root/backups/databases/$DBASEBACKUPNAME
TIMETEMDIR=/root/backups/databases/$DBASEBACKUPNAME
# Dump Databases to /root/backups/databases/databasesBackup-$TIME folder
mysqldump -u $MYSQLUSER -p $MYSQLDBASE1 > $TIMETEMDIR/$FILENAME1
mysqldump -u $MYSQLUSER -p $MYSQLDBASE2 > $TIMETEMDIR/$FILENAME2
mysqldump -u $MYSQLUSER -p $MYSQLDBASE3 > $TIMETEMDIR/$FILENAME3
# Tar directory with database backups
tar -cazf $TIMETEMDIR/$DBASEBACKUPNAME.tar.gz $DESDIR
# Delete folder with SQL file backups
rm -r $TIMETEMDIR
mail -s "CENTMIN MOD Database Backup $TIME" mail@example.com <<< "CENTMIN MOD domain database backup has been completed."

Modify the Permissions on the File

Code:

chmod +x /root/tools/backup-databases.sh

Access the Cron Interface

Code:

crontab -e

Cron Job (will run everyday at 11PM)

Code:

01 23 * * * /root/tools/backup-databases.sh 2>/dev/null

 

Thanks for the info! I'll read those over!
