Amazons Simple Storage System (S3), one of the online booksellers Amazon Web Services (AWS) products targeted mainly at developers, offers some of the cheapest online storage available. Given Amazons size and how critical its IT/Internet infrastructure is, its also a good bet S3 will be among the most reliable and secure storage going.
But to make effective use of Amazons cheap online storage, you need an S3-compatible program. One of the first commercial developers with an S3 backup solution suitable for small businesses is CloudBerry Lab, a Russian company.
CloudBerry charges a one-time fee of $29 for a software license, which includes one year of free updates and e-mail support. Then you pay Amazon for storage and other fees. S3 storage fees start at a high of 15 cents per gigabyte (GB) per month for the first 50 terabytes (TB), and they go down from there.

Transfer fees are a flat 10 cents per GB to transfer data into S3. Transfer fees to get data out of S3 start at a high of 13 cents per GB for the first 40 TB and go down from there. And each time you request a transfer or a list of files or a request to copy or move files, Amazon charges you one penny. (Requests to delete files are free.)
Say you have 20 GB of data you want to protect with daily backups using CloudBerry. Youll pay Amazon about $2 ($0.10 x 20GB) initially to transfer data into S3. Storage will cost $3 ($0.15 x 20GB) per month. Add 30 cents ($0.01 x 30 days) a month for daily backups.
Total, including the cost of the software, transfers of incremental backups and occasional recovery of files: less than $100 a year.
Features: The Good and The Missing
CloudBerry Online Backup includes some good features that not all competing solutions offer. You can filter backups, by specifying types of files to include or exclude so you dont backup unneeded files.
And while some backup systems over-write files at the destination when the source changes, CloudBerry retains multiple versions so you can revert to an earlier one if needed. It even lets you choose how many previous versions and how long theyre kept.
But the CloudBerry software also lacks a few features at least for now. Most importantly, it cannot backup open files.
This means you must remember to close important files before a backup starts. In the case of some, such as Outlook database files (.PSTs), you have to shut down the program itself and any other programs using the file.
This is inconvenient if youre doing manual backups. If you schedule unattended backups, there is also the potential for data loss. Most people leave Outlook running all the time and will likely forget to close it. Result: vital data not backed up.
Open-file backup is one of several features on the companys to-add list. Another is virtual disk drive so your S3 bucket appears as a disk drive in Windows, and you can use Windows Explorer to access and retrieve files.
Our out-of-the-box experience with CloudBerry Online Backup was a long way from perfect. But remember: this is a beta product, meaning its a work in progress, possibly with unresolved problems.
Signing up for Amazon S3 is simple enough. If youre already an Amazon customer, simply log in to your account, choose a billing address and credit card to bill charges to and click the button to complete the transaction. If youre not a customer, youll have to choose a password and enter address and credit card information.
Amazon sends you an e-mail with a link to a page where you retrieve your AWS Access Key ID and Secret Access Key, two long strings of characters that youll need to access your S3 space from CloudBerry (or any S3-based application).
Downloading and installing the CloudBerry software is uneventful. And the interface is simple and intuitive, with four tabs across the top: Welcome Page, Backup Plans, Online Backups and History.
The first step is setting up a first Backup Plan, using a wizard launched from the Welcome Page.
The wizard includes a Windows Explorer-like interface for selecting folders and files to back up. The default option is backing up all files in selected folders. Or you can enter types of file you want included (e.g. *.doc to back up only Word documents), or excluded (e.g. *.tmp to prevent it backing up temporary files).
CloudBerry offers the option to compress files for backup or not. Compressed files take up less space but compressing and decompressing slows transfers. And you can choose to encrypt files to prevent prying eyes seeing them or not.
The Backup Plan wizard also lets you customize version retention options, specifying how many previous versions of a file you want to retain and for how long.
