The server is running Windows Server 2008 and my backup routine is simply a scheduled bat/cmd file to copy everything to a temp folder, then zipping it to a single file that I move off site (I used to ftp it to another host but you cannot use ftp with S3)

So, I needed to be able to upload my zip file to Amazon S3 using the command line. But unfortunately the only S3 copy or backup tools I found for Windows was either graphical and user driven or required Java, Perl or such and I didn’t really feel like installing any of that stuff on my server just for this simple task.

The solution was to write my own copy routine in C# (.NET Framework 2.0) which I did using one of the many S3 libraries available, in my case I selected the Affirma Threesharp C# Library. The result is a very simple copy routine, you can only copy one file at a time, no wild cards etc. I will probably extend it in the future, for example a delete routine so I can also automate deleting old backups (I’m currently using the s3fox plugin for Firefox to check on my backups and do deletes about once a month)

Syntax: s3copy Localpath Bucket Filename AccessKeyId SecretAccessKey

Example: s3copy.exe c:\backup\ mybackupbucket backup.rar MyAccessKeyId MySecretAccessKey

It’s a single exe file. No need to install anything, the dll is contained in the exe. Feel free to use it if you like!
