The program is easy to set up, you just need two things:
To get an Amazon S3 account is simple. Just go to http://aws.amazon.com/s3 and click the "Sign Up For This Web Service" at the right border of the page. If you already are an Amazon customer, you can use the account you already have. But do not forget to sign up for the S3 service, which is needed in addition to the Amazon Account.
The prices for using this service are also available on the page http://aws.amazon.com/s3.
Once you have signed up for Amazon S3 you can click on the "Your Web Services Account" and choose "AWS Access Identifiers". It will show you a page where you can get your "Access Key ID" and your "Secret Access Key" (which needs to be unhidden by clicking on it). You will need both keys to use JaBaS3.
Now start JaBaS3: Click here to start
You will get a program with two tabs, one for backup the other for restoring your files. On each page you can enter the Amazon Keys and your personal password that is used to encrypt and decrypt the saved files.
When you have entered the Amazon Keys and your password, choose the directories you want to backup and then click the "Backup" button. The selected directories are now encrypted and uploaded to Amazon's S3 service.
When the program has finished uploading your data, you can switch to the "Restore" view and click "Login". It will show you your data that is stored in Amazon S3 in the tree view. You can select single files or complete directories to be restored.
At the bottom of the window you can choose where the selected files should be restored. You can start the restore process by clicking the "Restore" button.
In the "Settings"-dialog, which you can access by the "Settings"-button at the bottom of the backup dialog, you can configure several advanced features of the program:
If you want to back up more than one computer, you can use the "Store prefix" in the settings dialog. It names a path that is prepended to all files that you backup. It is easy, just use a different "Store prefix" for every computer, e.g. the name of the computer, and you can see in the "Restore" view from which computer the backup was.
The "Number of versions to keep" setting allows you to specify how many old versions of a file should be kept when new versions are saved. You can see the different versions of a file when you use the tree view in the "Restore" view and open the symbol of a file in the view.
By checking the "compress files" checkbox, you can save money, bandwidth and time. It is normally checked by default. When file compression is turned on, all your files are compressed before they are encrypted and transferred to Amazon S3. During restore they are automatically decompressed, independent of this setting. Currently the gzip compression algorithm is used.
