REMOTE BACKUP

Client-server application that perform an incremental backup of the content of a folder.

Architecture

• high level client architecture https://whimsical.com/client-v2-LA4fGCYtwK7kxcj2D5j48U

Technologies

• cpp 17
• Boost asio
• Redis
• Docker (multi-stage build and compose)
• OpenSSL

Properties

• multi-user
• multi-thread
• portable
• reilient,i hope :)
• customizable delays
• easily expandable

Try it

Launch server

in root dir type: docker-compose up , this will download the server image (already built), and run it. (if you want to build manually, just edit docker-compose.yml)

• data volume is mounted at /server/DATA
• redis volume is mounted at /server/redis

Launch client

You need to copy client.docker-compose.yml inside the folder you want to dynamic-backup. reneame it in docker-compose.yml and edit last record with desired arguments:

• arg1 username (available: ivan,francesco,alberto)
• arg2 password (default: "mimmo")
• arg3 server-host (if you run server in same machine of the client put host.docker.internal otherwise the ip of the server )
• arg4 server-port
• arg5 file_watcher delay (milliseconds) determines the interval between filesystem scans
• arg5 snapshot_delay (seconds) determines how often the client requests a fresh copy of the remote filesystem structure

After the edit just run: docker-compose up.

• The volume shared with container is the directory itself.

Setting-up environment for developing on windows over linux subsystem

Requirements

• docker

1 - setup wsl2 for work on win clion

https://www.jetbrains.com/help/clion/how-to-use-wsl-development-environment-in-clion.html#wsl-tooclhain

Needed package (linux,wsl2) :

 apt-get update \
  && apt-get install -y ssh \
  build-essential \
  gcc \
  g++ \
  gdb \
  clang \
  cmake \
  rsync \
  tar \
  python \
  gdbserver \
  openssh-server\
  libssl-dev\
  libboost-all-dev\
  netcat\
  && apt-get clean

2 - setup cpp_redis setup (linux,wsl2)

# Clone the project
git clone https://github.com/cpp-redis/cpp_redis.git
# Go inside the project directory
cd cpp_redis
# Get tacopie submodule
git submodule init && git submodule update
# Create a build directory and move into it
mkdir build && cd build
# Generate the Makefile using CMake
cmake .. -DCMAKE_BUILD_TYPE=Release
# Build the library
make
# Install the library
make install 

3 - start redis

go to redis folder and simply launch docker-compose up

4 - You're ready to working with Clion (windows) over linux-subsystem
