A simple Bash Script I made To Backup My Files.

backup.sh

#!/bin/bash
SRCDIR="files"
#Set to 1 to delete backup files older than 30 days. otherwise set to zero
RemoveOldBackups=1
#Set a filename based on date and time.
FILENAME=$(date +"%FT%H%M%S").tgz
#Make backup folder
mkdir -p "Backups"
#This is the backed up filename.
BACKUP_FILE="Backups/$FILENAME"
#Display message
echo "Running Backup."
#Compress the $SRCDIR
tar -cvf $BACKUP_FILE $SRCDIR
#Get size of backup file.
BACKUP_SIZE=$(stat -c%s $BACKUP_FILE)
#Delete files more than 30 days old
if [ $RemoveOldBackups = 1 ]; then
	find ./Backups -type f -mtime +30 -exec rm -f {} \;
fi
#Display status
echo ""
echo "Backup File Created : $BACKUP_FILE"
echo "Backup File Size    : $BACKUP_SIZE bytes(s)"
echo "Finished backup."
