About The Project

This is a microservice where the program creates backup file of path specified by the user.

The backup automation will begin once the client program is connected to the server by Socket. The backup files will be saved in ./backup_file directory.

The microservice sends back the path of the latest backup file when a request is made from the client program.

Uses

• Python
• Socket

Instruction

Communication between the server(microservice) and the client program is made via Socket.

Request Data

How to request data from the microservice:

1. Import socket module

   import socket

2. Create a socket object

   s = socket.socket()

3. Define the port on which you want to connect

   port = 12345

4. Connect to the server on local computer

   s.connect(('127.0.0.1', port))

5. Send request data by encoding the string

   request = "revert"
   s.send(request.encode())

   • The microservice will respond to "Backup" and "backup" for creating a backup file.
   • The microservice will respond to "Revert" and "revert" for retrieval of lastest backup file.

Receive Data

How to receive data from the microservice:

• Receive the data by decoding to get the string

  s.recv(1024).decode()

  • The decoded string will the absolute path of the backup file.
