How to Upload Frequently Updated Files on Amazon S3 Without Data Loss?

To ensure files are uploaded without data loss, Bucket Explorer calculates and sends a hash of every file to Amazon S3.

If you are facing a problem of data loss during upload like file is modified at local while upload, then you have to make a change in the default settings of Bucket Explorer Configuration . With default setting, Bucket Explorer uploads the user’s data directly to the Destination Bucket without copying it to temp folder.

For Example:
If you are a Webmaster, and want to backup your Web Server (IIS / Apache) logs on S3. But the Web Server logs get updated with every user request, so the files will keep on changing frequently. And if you are uploading this type of files on S3 for backup, then you will face the data loss problem. To avoid this problem, Bucket Explorer provides a facility to upload the files without corruption. For this you are required to make small change in Bucket Explorer Configuration

You can do same by another way

1. Click on Tools->Advance Preference
2. Select "True" the CopyToTempBeforeUplaod ComboBox
3. Click on OK button.
4. Now when you upload any file, it will be copied to temp before starting upload operation

Older Version (Before Version 2009.10)

1. Open BucketExplorer.xml from config folder
2. Locate the property CopyToTempBeforeUpload & change its value to TRUE. By default it is set to FALSE.
3. Save the file & Run Bucket Explorer as usual.

If this tag is set to FALSE then file won’t be copied to Temp folder of Bucket Explorer before uploading to S3. But if it is set to TRUE then in every uploading process, file will first be copied to Temp of Bucket Explorer and then to S3 from Temp .
NOTE: Changing the property value to TRUE will be helpful to avoid the data loss, but in case of large files it will take time in copying.
