自动备份VPS数据到Dropbox

最近一直在考虑备份的问题,因为随着站越来越大,付出了两年的心血,如果真因为没有备份而导致数据丢失,那就真是欲哭无泪了,而对于那么多的站点及数据,如果要时常备份,肯定会烦躁的,在网上找到了一个脚本,专门可以把VPS上的数据和数据库中的数据自动备份到dropbox中。

dropbox是什么?不解释,美丽的度娘,万能的谷哥,等着你去找他们。

[code lang=”bash”]
#!/bin/bash
DROPBOX_USER="Your Dropbox username" #dropbox账号
DROPBOX_PASS="Your Dropbox password" #dropbox密码
DROPBOX_DIR="Directory in your dropbox account to store the backups, e.g. /backups" #dropbox中存放备份的文件夹
BACKUP_SRC="/home /var/www /var/git /etc /root" #VPS中需要备份的目录
BACKUP_DST="/tmp" #备份存放的地方
MYSQL_SERVER="127.0.0.1" #本地数据库服务器
MYSQL_USER="root" #数据库用户名
MYSQL_PASS="Your MySQL password" #数据库密码
#下面的就不需要修改了

#
# 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"

[/code]

代码只需要在几个地方修改,已在上面的代码中注释出来。

直接:

[code lang=”bash”]
#随便找个地方,存放backup.sh,比如我:
#cd /home/wwwroot/到这里来放置这个shell script
vi backup.sh
#粘贴上代码后
chmod +x backup.sh
#因为授予了权限,所以直接运行即可:
./backup.sh
#接着设置定时任务,可以man crontab自己看看具体用法
$ crontab -e
# m h dom mon dow command
#这里分别对应minute hour ‘day of month’ month ‘day of week’
#下面这行,意思就是每月第一天备份
0 0 1 * * /bin/bash /home/wwwroot/backup.sh
[/code]

OK,玩网站,就一句话,勤备份,靠别人不如靠自己,要想玩得好,首先要勤劳!
