如何将文件上传到Amazon S3存储桶并维护版本
[英]How to upload Files to Amazon S3 bucket and maintain versions
问题描述
I am stuck in middle of the development for the application which takes backup of some folders automatically everyday and have to implement and maintain different versions of files 
我陷入了应用程序开发的中间阶段，该应用程序每天自动备份一些文件夹，并且必须实现和维护不同版本的文件
For example: 例如：
- Backup was started on 1 April 11 PM for the first time which uploaded 10 files 备份是从4月1日晚上11点开始的，首次上传了10个文件
- on 2nd April, 2 more files were added and 1 existing file was updated 4月2日，添加了2个文件，并且更新了1个现有文件
- Likewise everyday the backup will upload all the files automatically 同样，每天备份将自动上传所有文件
- On 10th April, user wants to get the files of 1st April only because the file which were uploaded on 1st April was good and out of that files, 1 of the file got corrupted 在4月10日，用户只想获取4月1日的文件是因为4月1日上传的文件是好的，并且其中的1个文件已损坏
I don't want to re-upload all the same files on S3 bucket or some cloud drive if the file isn't updated but I do want to maintain the versions of the files. 如果文件未更新，我不想在S3存储桶或某些云驱动器上重新上传所有相同的文件，但我确实希望维护文件的版本。
How can I achieve it without re-uploading the file which is not changed and yet have the ability to restore the previous days version. 如何在不重新上传未更改的文件的情况下实现该功能，而该文件仍具有还原以前版本的能力。
Thanks in advance for your help!!!! 在此先感谢您的帮助！！！！
