Versioning is an exciting new feature that makes Amazon S3 that allows you to create versions of objects instead of overwriting them and keep them on S3. Versioning support dramatically increases a range of Amazon s3 of possible applications and it is only limited by your imagination. It is currently in beta and as of February, 8 2010 supported across all Amazon S3 regions.
Newer version of CloudBerry Explorer comes with support for versioning. You can turn on versioning aware mode, turn on versioning for specific buckets and perform common file operations on versions. This article will give you some ideas on how to get started.
How CloudBerry Explorer supports Versioning
To turn versioning on for a specific bucket click versioning in the context menu and check the appropriate checkbox. Now you will be able to create versions of the objects for that bucket.
Try to copy an object with the same name to the bucket several times. To see versions click Show Versions item in the context menu
This option will show a bottom panel with the list of versions for a selected file. . Current revision is version of the object that is available using regular Amazon S3 API. Now you can do all the regular file operations with the versions such as copy, delete, move, rename, etc.
What about deleted files
As you can guess (or read in the versioning documentation) when you turn the versioning on for a bucket, and then delete a file a new version is created with deleted attribute. This is awesome if you delete file by mistake as you can quickly restore it. To show the deleted file you have to turn on a corresponding option. This option is global and found in Tools | Options in the main menu.
Once you have done that try deleting a file in the bucket with versioning turned on. You will notice that the file becomes grayed and you will see a new version created in the versioning panel marked as deleted.
If you want to restore a deleted file or just any version of a file select the version and click Restore button. The file will be available again.
What’s next
Our CloudBerry Backup users know that we have our own implementation of file versioning. We have done that awhile ago before Amazon announced its versioning implementation. We are going to replace our own versioning with Amazon S3 native versioning as we believe it is more efficient to rely on the platform rather than inventing own things. Stay tuned!
