This project provides a Client-Server application that performs an incremental backup of a given folder, and lets you restore the version of a given date.
For each day, the last version of each file is permanently stored to allow the restore operation.
This project's objective is to test our skills with a simple Client-Server interaction in a multithreaded environment, so security issues have not been taken in consideration: packets are not encrypted and passwords are stored in plain text.
The database, based on sqlite3, is composed of a users table and one table for each user.
| username | password |
|---|---|
| TEXT | TEXT |
| filename | timestamp | file | size | action | hash | last_write_time | permissions |
|---|---|---|---|---|---|---|---|
| TEXT | TEXT | BLOB | INT | INT | TEXT | TEXT | TEXT |
Developed on Linux environment (Ubuntu 20.04).
Clion required.
Install the following libraries:
- Boost -> sudo apt-get install libboost-all-dev
- SQLite3 -> sudo apt-get install libsqlite3-dev
- libSSL -> sudo apt-get install libssl-dev
(libSSL is only used to compute hashes for file comparisons)
Launch Clion and import Client and Server Folders.
Launch Server and Client independently through the Clion interface.
If it's your first time launching the Client, it will ask you for the folder
to monitor and a password, the username will be automaticaly created through the
linux machine-id.
Your folder will be constantly monitored and the data will be automatically sent
to the server.
- "q" close the program
- "r" restore a previous version of the monitored folder, ask for a specific date to restore ("YYYY-MM-DD" format) and the folder in which to store the backup.
By changing the _DEBUG value in Debug.h (present both in Client and Server folder) from 0 to 1, it's possible to show additional messages that describe the exchange of data between Client and Server, as well as other useful information.
