box.net desktop client

A powerful backup and sync software, but it seems it is available on Mac now. Expecting its PC version.


AOL service


    • 5G free space

xdrive desktop (Highly recommended.)


      • you can storing files as your local drive
      • or you can use its software interface to backup or mirror* your files (only My Pictures, My Music, and My Videos folders can be Mirrored)
      • support incremental backup*, and you can choose keep how many backups you want to keep. Read one of the F&Q in Xdrive site, you will understand what I say.
        (If I backup incrementally, and I choose to keep up to 7 backups, what happens on the 8th?
        The system uses a practice called promotion, which merges the two oldest backups in the account into one. Promotion compares the file versions of the two oldest backups, moves the newest files into the second-oldest backup, and deletes the oldest. This way you can keep all of your important files backed up without having to store an unlimited number of backups.)
      • Dosen’t support Chinese folders and files name.

*Incremental backup. It only adds the modified or new created files since last backup in a new file named by the date. This saves your time when you making online backup. It won’t delete any files, even won’t replace old version files.

*Mirror. The backup is exactly the same is the original one. (ignoring some insignificant faults, Mirror=incremental backup +deleting files+replacing files)

Backup huge sum of files to your email account

leave a comment »

In my last post, I introduce many methods to backup files online. But when I try to backup large sum of files, for example, my 2.3G pictures, the upload process is not stable. It stop sometimes for some reasons and I have to start it from the beginning. Using email client to upload files to your email account may be more reliable and convenient.

Let’s see what we need first.

  1. A compress software (Win RAR in this post)
  2. An E-mail client (Outlook Express in this post)

OK, let’s see how to do it.

  1. Select folders or files you need to upload, right click the folders and select Compress and E-mail…
  2. Limit single compressed file’s size to 19 mb (no more than the email account attachment size limitation, 19 mb is save)
  3. In file tag, check compress every file to single compressed file and compress files and E-mail to, then type E-mail address which you want to upload files to. ( I’m using Chinese edition, hope the translation is correct)
  4. Click OK, and the compress process begins, after that, your files will be sent by your email client.

You may not want your email client send your compressed files instantly, because Win RAR will not compress the next file until the last one is sent out. Go to your email client (here is Outlook Express), find option, select the send tag, uncheck send E-mail instantly. Now, you can compress all your files in one time and send any sum of them any time.


  1. Don’t forget to delete sent emails from your computer after uploading, or you will run out of your drive space soon.
  2. Choose a high speed connecting email account as your email client account.
