Amazon S3 data backup: Preserve deleted data in trash to prevent data loss

Using this feature, you can retrieve all deleted file(s) in the  same structure [1] as it is stored in your Bucket. In Bucket Explorer, trash folder is located in two default system Buckets named as us.bucketexplorer.md5. ( Canonical Id [3] ) and eu.bucketexplorer.md5 (Canonical Id). This feature is cost effective because empty buckets don't cost money.

If you delete anything in system Buckets, it will be deleted permanently and you don't need to use another third party tool for this.

How Trash Works for Amazon S3 Buckets/ Files and Folders: (Note: This is possible only when Amazon versioning is 'Disabled', Bucket Explorer will then handle its own versioning. )

Whenever you delete any file in Amazon S3 with "Move to Trash" option, deleted objects are automatically moved to trash folder of the  relevant system bucket [2] . This is especially useful to prevent data loss. (It's like a Recycle Bin). Nothing will ever go to "Trash" folder if you choose Quick Delete .

In simple delete, if you choose "move to trash", then only the data will go to "trash" folder. So if you don't want to send the deleted object in trash, you can choose the "delete permanently" option instead of "move to trash" option. You can download , copy , move and delete data from the Trash folder using Bucket Explorer.

  1. ˆ Same structure: In system bucket, Bucket Explorer creates a folder named as Bucket name from where you deleted the object. In this folder, it will be of the same folder structure as in Bucket and the object name in folders gets appended with date and time.
  2. ˆ Relevant system bucket: There are two system buckets in Bucket Explorer for US and Europe. Version of US buckets is stored in us.bucketexplorer.md5 (Canonical Id) and version of Europe buckets is stored in eu.bucketexplorer.md5 (Canonical Id).
  3. ˆ Canonical Id: The canonical user id is specific to S3 and is a 64 character long hex string.
