JS3tream was written to provide easy streaming of data to and from Amazons S3 data storage service. JS3tream is NOT a backup solution by itself. But, coupled with tar or zip, JS3tream provides a very powerful backup solution.

Install the Sun JVM using the following command

sudo apt-get install sun-java5-bin

You will need the zip/unzip utility to extract the JS3tream utility

sudo apt-get install unzip

Go to the JS3tream web site, and download the latest zip file. Extract this file to a directory of your choice. Eg /usr/local/bin

cd /usr/local/bin

unzip js3tream-0.6.2.zip

Test to make sure both java and JS3tream are correctly setup. Start by going to the directory you put JS3tream.

cd /usr/local/bin

Make sure java is correctly installed. I happen to have 1.5.0.11

sudo java -version

java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode)

Test that JS3tream can be executed.

sudo java -jar js3tream.jar --help

At this point JS3tream should be correctly installed. Now, it's simply a matter of following the examples and howtos on the JS3tream web site.
