Linux免dropbox客户端备份脚本

还不知道dropbox是什么玩意?dropbox_百度百科http://baike.baidu.com/view/2998059.htm

脚本来源:http://www.andreafabrizi.it/?dropbox_uploader

脚本的原理:利用curl(字符串浏览器)模拟网页上传。好处是不需要在vps装dropbox客户端,从而降低vps内存消耗,缺点:不能像安装dropbox客户端那样同步备份。

操作步骤:

wget http://linux-bash.googlecode.com/files/uploader.sh

下载脚本

chmod 777 uploader.sh

修改权限

bash uploader.sh dropbox登录帐号 登录密码 本地文件路径 上传文件路径

执行脚本

目前只能上传单个文件,还不能上传整个文件夹。

通过上面脚本,我们很容易就可以做出备份文件数据和数据库的脚本备份到dropbox中,然后通过crontab定时每天备份。

我找到了1个根据上面脚本改写的备份脚本,转载自http://davehope.co.uk/Blog/backup-your-linux-vps-to-dropbox/

#!/bin/bash
DROPBOX_USER="Your Dropbox username"  #dropbox用户名
DROPBOX_PASS="Your Dropbox password"  #dropbox密码
DROPBOX_DIR="Directory in your dropbox account to store the backups, e.g. /backups"  #dropbox上存放备份文件目录
BACKUP_SRC="/home /var/www /var/git /etc /root" #vps上需要备份的目录 多个目录以空格隔开
BACKUP_DST="/tmp"  #本地临时存放文件或者数据库的目录
MYSQL_SERVER="127.0.0.1" #mysql数据库地址
MYSQL_USER="root"  #mysql数据库用户名
MYSQL_PASS="Your MySQL password" #mysql数据库密码

#
# Stop editing here.
NOW=$(date +"%Y.%m.%d")
DESTFILE="$BACKUP_DST/$NOW.tgz"

#
# Upload a file to Dropbox.
# $1 = Source file
# $2 = Destination file.
function dropboxUpload
{
	#
	# Code based on DropBox Uploader 0.6 from http://www.andreafabrizi.it/?dropbox_uploader
	LOGIN_URL="https://www.dropbox.com/login"
	HOME_URL="https://www.dropbox.com/home"
	UPLOAD_URL="https://dl-web.dropbox.com/upload"
	COOKIE_FILE="/tmp/du_cookie_$RANDOM"
	RESPONSE_FILE="/tmp/du_resp_$RANDOM"

    UPLOAD_FILE=$1
    DEST_FOLDER=$2

	# Login
	echo -ne " > Logging in..."
	curl -s -i -c $COOKIE_FILE -o $RESPONSE_FILE --data "login_email=$DROPBOX_USER&login_password=$DROPBOX_PASS&t=$TOKEN" "$LOGIN_URL"
	grep "location: /home" $RESPONSE_FILE > /dev/null

	if [ $? -ne 0 ]; then
		echo -e " Failed!"
		rm -f "$COOKIE_FILE" "$RESPONSE_FILE"
		exit 1
	else
		echo -e " OK"
	fi

	# Load home page
	echo -ne " > Loading Home..."
	curl -s -i -b "$COOKIE_FILE" -o "$RESPONSE_FILE" "$HOME_URL"

	if [ $? -ne 0 ]; then
		echo -e " Failed!"
		rm -f "$COOKIE_FILE" "$RESPONSE_FILE"
		exit 1
	else
		echo -e " OK"
	fi

	# Get token
	TOKEN=$(cat "$RESPONSE_FILE" | tr -d '\n' | sed 's/.*<form action="https:\/\/dl-web.dropbox.com\/upload"[^>]*>\s*<input type="hidden" name="t" value="\([a-z 0-9]*\)".*/\1/')

	# Upload file
	echo -ne " > Uploading '$UPLOAD_FILE' to 'DROPBOX$DEST_FOLDER/'..."
    curl -s -i -b $COOKIE_FILE -o $RESPONSE_FILE -F "plain=yes" -F "dest=$DEST_FOLDER" -F "t=$TOKEN" -F "file=@$UPLOAD_FILE"  "$UPLOAD_URL"
    grep "HTTP/1.1 302 FOUND" "$RESPONSE_FILE" > /dev/null

    if [ $? -ne 0 ]; then
        echo -e " Failed!"
		rm -f "$COOKIE_FILE" "$RESPONSE_FILE"
        exit 1
    else
        echo -e " OK"
		rm -f "$COOKIE_FILE" "$RESPONSE_FILE"
    fi
}

# Backup files.
mysqldump -u $MYSQL_USER -h $MYSQL_SERVER -p$MYSQL_PASS --all-databases > "$NOW-Databases.sql"
tar cfz "$DESTFILE" $BACKUP_SRC "$NOW-Databases.sql"

dropboxUpload "$DESTFILE" "$DROPBOX_DIR"

rm -f "$NOW-Databases.sql" "$DESTFILE"

要修改的部分

DROPBOX_USER="Your Dropbox username"  #dropbox用户名
DROPBOX_PASS="Your Dropbox password"  #dropbox密码
DROPBOX_DIR="Directory in your dropbox account to store the backups, e.g. /backups"
#dropbox上存放备份文件目录
BACKUP_SRC="/home /var/www /var/git /etc /root" #vps上需要备份的目录 多个目录以空格隔开
BACKUP_DST="/tmp"  #本地临时存放文件或者数据库的目录
MYSQL_SERVER="127.0.0.1" #mysql数据库地址
MYSQL_USER="root"  #mysql数据库用户名
MYSQL_PASS="Your MySQL password" #mysql数据库密码

放到计划任务中定时备份

$ crontab -e
0 0 1 * *       /bin/bash /root/DropboxBackup.sh
