Prevent Amazon S3 Data Loss by Version and Trash Feature of Bucket Explorer

^New System buckets are created only when you perform operations like move to trash, copy, move, and upload file less than 5 GB in size in multiparts corresponding to its region end-point.

System Buckets are special Buckets generated ONLY by Bucket Explorer to keep track of deleted & updated files.There are two System Buckets named as us.bucketexplorer.(SHA1 of Canonical Id) and eu.bucketexplorer.(SHA1 of Canonical Id) available for the same purpose. This feature is cost effective because empty buckets do not cost money.
us.bucketexplorer.(SHA1 of Canonical Id) keeps track of the different operations performed on US and US-West (Northern California) Buckets. And eu.bucketexplorer.(SHA1of Canonical Id) is for Europe and AP-SouthEast-1(Singapore) Buckets only.

Note : In older version of BucketExplorer 2009.10, system bucket names were us.bucketexplorer.(SHA1of Access Key) and eu.bucketexplorer.(SHA1of Access Key).Using this feature you can retrieve all deleted file(s) and older version of overwritten file(s) in same structure ^[1] as it is stored in your Bucket.

You can download , copy , move and delete data from the system buckets using Bucket Explorer but can not upload, copy and move data in these buckets explicitly. Anything deleted from the system Buckets is permanently deleted and you don't need to use another third party tool for this.

In the System Bucket there are 3 folders:

1. Versions
2. Trash
3. Work Area

ˆ  Same structure: In system bucket, Bucket Explorer creates a folder named as Bucket name from where you deleted object, in this folder there will be the same folder structure as in Bucket and object name in folders gets appended with date and time.
