Use a VPS to do everything you need to worry about, backup is also. Backup services like Linode are charged, and one months is 5 dollars. It's better to have plenty of money than to spend 5 dollars. Install the Dropbox for the service and set the Sync service to 4:00-6:00 on a daily basis. Run two scripts before, automatically back up Web folders and MySQL databases.
All two scripts are backed up to the/root/dropbox/backup directory, and the backup is automatically deleted 10 days ago. A Web backup is a weekly row that deletes a backup 30 days ago.
one, back up Web Folders
1, Backup/home/users/public_html directory
2. Modify crontab to run on the first day of the week 3:22
Copy Code code as follows:

3. Copy script to/etc/cron.weekly directory
4, modify the permissions
Copy Code code as follows:
chmod 0755/etc/cron.weekly/webbackup.sh
5, the script is as follows
Copy Code code as follows:
#!/bin/sh
Filename= ' Date +%y%m%d '
Backup_dir= "/root/dropbox/backup/web"
#delete All files ten days ago
Find $backup _dir-mtime +30-name "*"-exec rm-rf {} \;
#each user you want backup
users= "Baidu Sina"
For user in ${users}; Todo
Tar zcvf $backup _dir/$user $filename.tar.gz/home/$user/public_html
Done
6, note that the sentence filename is not single quotes, above the TAB key
7, to back up the user's public_html directory, the user will be filled into the users
second, MySQL database daily backup
1, for security, new user backup, with strong password (automatically generated), global permissions for Select,lock tables

Copy Code code as follows:
#!/bin/sh

Backup_dir= "/root/dropbox/backup/mysql"
#delete All files ten days ago
Find $backup _dir-mtime +10-name "*"-exec rm-rf {} \;
#Do each database backup
For data in ${datas}; Todo
$bin _dir/mysqldump--opt-u$dbuser-p$dbpassword $data | gzip > $backup _dir/$data $filename.sql.gz

6, the same as the 6th article
7, to back up the database to fill in the Datas
third, the feeling
Because of all the reasons in the United States, backup to Dropbox fast, a 10M file backup to Dropbox, from the open Dropbox service, immediately refresh Dropbox site can be seen.
If the flow is very tense, you can also set the Dropbox for the weekly run, or every 5 days running and so on. It should be required to set up a backup cycle, or use it together.
