Install python-pip
Install using apt-get for quick.
alex@Alex-Laptop:~$ apt-get install -y python-pip
alex@Alex-Laptop:~$ python --version
Python 2.7.6
Install component packages
After we install pip now we can install all requirement packages.

wait until installing finish.
Testing
See es-config.json please add your aws_access_key_id and aws_secret_access_key for your bucket.
alex@Alex-Laptop:~$ ./es-backup-restore.py
Usage: es-backup-restore.py [OPTIONS]
example: es-backup-restore.py -c es-config.json -a localhost -p 9200 -b backup|restore
Where OPTIONS:
-a HOST Specify URL address of the Elasticsearch server
-p PORT Specify Port of the Elasticsearch server
-c FILE Specify path of config file
-h Printing the help
-b To do job ex:backup or restore
-v Print the version
well in the OPTIONS we can see how to work with this script.
just follow that example if you want to backup use option -b with backup and if you want to restore change with restore.
NOTE : this code only work in same server with elasticsearch machine.
