Online Backup by 77Backup

The short answer : yes

The longer answer : yes.

When you backup to 77backup, the first thing that happens to your data, before it leaves your machine, is that we encrypt it using the password you chose when you setup the program.

This encryption means that only you can get at your data.  What’s more, several copies of your data are kept – so even if something horrible happens to OUR datacenter, then we’ll always have other copies.

One byte is enough memory to store 1 letter – so to store the word ‘hello’, you need 5 bytes of memory. 

To store an MP3 file, you’ll need on average 1Megabyte (1MB, or 1 000 KB, or 1 000 000 Bytes) per minute the song lasts – so for a song which lasts about 3’30″, you’ll need about 3.5MB.  If you have 10 MP3s to save, you’ll need somewhere between 35 and 40MB

The average photo you take on your digital camera will take up between 500KB and 2MB (it all depends on the number of megapixels your camera is).

So if your pictures take up 2MB each, you’ll be able to backup around 500 with 1GB (1000MB)

Please note – these numbers are approximate, and, yes, we know there are 1024K in a M, and 1024M in a G and so on

Note to our readers and users.
Although, the previous beta version of the software had Plura in it, the new version (as of june 2010) does NOT include plura or any kind of task not related to backup.

Plura is a very small program which is installed with the sponsored version of 77Backup.

In the sponsored version, in exchange for free backup space on our servers, you let us use a small part of your CPU time for scientific calculations.  Plura is the module which does these calculations.

Plura does not, in any way, shape or form, take over your computer, or interfere with your normal computing actions. Plura kicks in when your computer is running but idle, making use of extra CPU cycles that would otherwise be wasted. When you put your computer to sleep or turn your computer off, Plura stops running. And the Plura application is a low priority application – meaning, it sits at the bottom of the food chain. If you need your computing power for other tasks, Plura waits until there is excess capacity once again.

You should backup any information that you wouldn’t be able to easily replace, if you had to change your computer.

There’s no point in backing up your “C:\Windows” directory for example – this data will be available on a new machine.  However, if you bought a new PC, then your “My Pictures”, or “My Music” folders would no longer have your files in them.

We recommend that you backup your “home” directory.

• In Windows XP, this directory is called “C:\Documents and Settings\<your username>”
• In Vista or Windows 7, you should choose the “C:\Users\<your username>” folder
• In MacOS X, choose “/Users/<your username>”
• Under Linux, your home directory depends on the version of Linux you run.  It’s usually “/home/<your username>”.  Open a terminal window, and type “pwd” to find out which directory is your home directory.
