Note: this post applies to CloudBerry Explorer 2.6 and later.
As always we are trying to stay on top of the new functionality offered by Amazon S3 to offer the most compelling Amazon S3 and CloudFront client on Windows platform.
With this release we are introducing support for Multi-Part Upload. This exciting new feature allows you to break large files into smaller parts (chunks) and upload them in any sequence. We think that this is most important enhancement to Amazon S3 service this year. (The second important enhancement has been the versioning support)
With Multipart Upload you can:
1. Make data upload more reliable, we need to re-upload only failed chunks, not the whole file.
2. Make data upload faster by breaking down the files into chunks we can upload the in multiple thread efficiently utilizing available network bandwidth
3. You can also pause and resume uploads.
To turn on multi-part upload go to the corresponding tab in the Tools | Options menu and make sure that use Multipart Upload option is on.
Everything else is happening transparently. The file is broken down and sent to S3 as a number of parts. Once all parts arrive the file becomes available.
You will also have an option to Pause and Resume large uploads.
Special note for our existing users, who use CloudBerry Explorer chunking: with addition of native Multipart Upload we are deprecating CloudBerry Explorer Chunking mechanism. It is going to be supported for backward compatibility so that you can retrieve the files from S3 that have been split using CloudBerry Explorer chunking. All new files will only use Amazon Multipart Upload.
Note for CloudBerry Backup users: we are going to add a support for Multipart Upload by the end of this year. We are also going to deprecate Advanced Mode that uses CloudBerry Chunking mechanism. What’s more we will also deprecate CloudBerry Versioning support and replace it with Amazon S3 native Versioning. This way we will try to fulfill our strategy to offer the product that doesn’t lock in the users to any specific data format and / or tool. You will always be able to retrieve your data using other Amazon S3 clients.
As always we would be happy to hear your feedback and you are welcome to post a comment.
