Upload Mydumper directories to S3.

Mydumper To S3

A tool that can upload mydumper dumped files to S3 bucket.

It works even while mydumper is running, for mydumper opened files, mydumper2s3 will wait mydumper to close those files then upload. --delete-after-upload option enables you to backup your MySQL without dumping all of your data to local disk.

It works like this:

+-----------+
|  mydumper |
+-----+-----+
      |
      |
      v
+-----+------+  upload  +-------------+      +------+
| local disk +----------> mydumper2s3 +------>  s3  |
|            <----------+             |      |bucket|
+------------+  delete  +-------------+      +------+
                after
                upload

Example

Upload files to S3 (If mydumper is running, you can still using this command, mydumper2s3 will search mydumper process pid and watch files opended by mydumper.):

$ mydumper2s3 --domain 127.0.0.1:9000 \
             --bucket test1 \
             --path ~/Downloads/target \
             --access_key AKIAIOSFODNN7EXAMPLE \
             --secret_key wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY \
             --upload-thread=10
138 files in directory,   0 dumping,   0 uploading,  138 uploaded.
138 files successfully uploaded.

You can check the backup with this command (available in your $PATH after install mydumper2s3):

$ verify-dump --domain 127.0.0.1:9000 \
              --bucket test1 \
              --path ~/Downloads/target \
              --access_key AKIAIOSFODNN7EXAMPLE \
              --secret_key wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
All files are exist both on local and on S3, file name check pass...
