After reading scripting.com and Dave Winer's article about Amazon S3, I decided to revisit using Amazons S3 as a backup solution. My server is running windows 2003 and I have been looking for a way to backup important files. I found this useful tool S3 Backup and thought I would give it a try. Its a GUI based backup solution that takes your files and stores them using S3. Amazon S3 stands for Simple Storage Service and is accessed by using webservices. S3 Backup is a GUI on top of the the webservices and allows you to schedule jobs to run when you want them to.
After activating my account at Amazon and installing S3 Backup, I have scheduled a job to backup all my important files to S3. For the last week, it has been running very smoothly. I then wanted to make sure that my files were secure and wanted a way to view my files. I installed a FireFox extension called S3Fox. This tool allows me to view my files, create buckets (folders) and upload/download files.
Another extension that I came across was GSpace. It allows you to upload files to the 2GB of storage that gmail give you. This sound promising so I decided to try it out. Here is how it works. You install the FireFox extension and then you can upload/download files and created directories just like Amazon S3. One glich that I found was that I had to open another tab and login to gmail to allow my GSpace extension the ability to login. When you upload a file it comes across as an email in your inbox. If you delete this email, the attachment (uploaded file(s)) are also deleted. Its a nice way if you want to store some files for retrieval on a different computer.
How about a comparison of the two:
- Cost:
- Amazon
- Pay only for what you use. There is no minimum fee, and no start-up cost.
- $0.15 per GB-Month of storage used.
- $0.20 per GB of data transferred.
- GMail (GSpace)
- FireFox Extension's are similar, almost identical
- Public Access
- Amazon
- you can upload a file and view it after changing the ACL to everyone. Here is an example: image
- GMail (GSpace)
- no way to view files unless logged into gmail
- Utilities
- Amazon
- many vendors creating useful tools to store data in S3
- GMail (GSpace)
- only one firefox extension found
Im my opinion, S3, S3Fox and S3 Backup provide a useful combination of tools to store your files offline. The files are encrypted and not made public. The costs so far have been minimal. After a week my costs are:
$0.20 per GB of data transferred 0.152 GB 0.04
$0.15 per GB-Month of storage used 0.009 GB 0.01
TOTAL COST: 0.05
The backup utility compresses the files for transfer and only stored changed files. This is the reason my costs have only been $0.05 for the week. If you try to download a backed up file with compression on, the file is unable to be opened. I will do more research to verify this, but it looks like you will have to use S3 Backup to retrieve the files that you have stored.
