Dropbox automatic backup script for WP space

If your space is a Linux system, the space is relatively large, with SSH permissions, so congratulations, you can use this script to achieve automatic backup of the entire WP to space or Dropbox on.

The script dobackwebsite.sh uses the Linux crontab function to realize the automatic timing backup function, and automatically deletes the expired backup file, saves the space, Cheng thinks that deletes the three days before the backup script, certainly you can make in the script automatically;-), below describes the script usage procedure.

1. The contents of the script are as follows

dobackwebsite.sh

2. SSH Landing Space

Build a directory back to the directory, put this script into this back directory.

3. Configure Crontab

Input CRONTAB-E, to configure the situation of Linux automatic operation, the specific parameter configuration can refer to another article about crontab.

For example, my configuration is as follows:

* * 1-7 Cd/home/user1/back/;bash dobackwebsite.sh

Represents the ability to perform an automatic backup of a dobackwebsite.sh script every 22:22.

4. Install Dropbox

Dropbox is a cloud storage service that can store files online and provide version-version management. Please refer to http://wiki.dropbox.com for details.

Installation Steps Reference Http://wiki.dropbox.com/TipsAndTricks/TextBasedLinuxInstall

$ cd ~

$ cd Wget-o dropbox.tar.gz http://www.dropbox.com/download/?plat=lnx.x86

$ tar-zxof dropbox.tar.gz

$ mv. dropbox-dist ~

$ cd ~

$ ~/.dropbox-dist/dropboxd &

At this time will prompt a string of URLs, ask you in the browser to enter this string URL will this virtual host connected to the Dropbox, after landing you can see the hint this machine has been connected to the Dropbox.

Note: This is the first time this need to configure this, the system will save the landing state will not need to manually enter the URL, which is also the script to achieve automatic backup to the above key.

Through the PS Auxgrep Dropbox to see if Dropbox has already run up, some words congratulations to you Dropbox configuration succeeded.

5. Complete the configuration

The first time you run dobackwebsite.sh manually, you have finished linking the virtual host to Dropbox.

This automatically backs up your site on a daily basis, and you can view the backup by Ls-oh. At the same time, if the receiving mailbox is configured, the system crontab will automatically send out a message to execute the result.

Cron Cd/home/user1/back/;bash dobackwebsite.sh

[OK] Back Up fly3q.com20100629.tgz

[OK] Fly3q.com20100629.tgz had Benn back to Dropbox.

[OK] DELETE fly3q.com20100626.tgz

[FAIL] Dropbox backfile->fly3q.com20100626.tgz not EXIST.

This side I haven't backed up fly3q.com20100626.tgz to Dropbox so failed, hehe.

At the same time look at the event inside Dropbox can see

6. Summary

This script is completely a hard to pack backup, backup files or put in space, it may be said or not safe, then of course, you can do in your machine to complete the automatic backup remote host files, and then ftp down to the local, so that there is no need to worry about space problems can not be restored in time. This implementation is also very simple, your machine to perform automatic backup, automatic login ssh, everything is done, if necessary, I can share it out.

But take into account our speed problem, the idea is given up, but I think a better way to put on the Microsoft 25G SkyDrive up, but it does not provide the corresponding API Yes, There is only one unofficial. Netapi, if there is a simpler jsapi, if you have any good ideas to welcome the discussion.

Now by Moonlight Blog An article inspiration, I put the backup on the Dropbox, Hehe, also be realized the cloud storage bar. Casually mention the host abroad to upload dropbox speed is fast, I pack the file 60M is basically a minute or so, it is done, envy such a speed.
