About Replica Folder Synchronization

Short Python script to synchronize two folders, source and replica. The challenge was not to use a third-party library like rsync to implement the synchronization.

Synchronizations works only one way and can be performed periodically. File and folder creation, copying and removal are logged into a logfile.

The script to perform a single synchronization is sync_folders.py.

There is two versions of calling this synchronization periodically:

• In the script sync_task_v1.py the synchronization is performed periodically via a while loop.
• In the script sync_task_v2.py the synchronization is performed periodically via setting up a task in windows task scheduler.

How to use

It is possible to run a single synchronization by calling sync_folders.py. This script has 3 required inputs:

- -s or --fld_src: Path to the source folder which is to be synchronized
- -r or --fld_sync: Path to the replica folder
- -l or --fld_log: Path to the folder in which the logfile will be created

Synchronization periodically via a while loop: The script sync_task_v1.py has 5 inputs of which 3 are required:

- -s or --fld_src: Path to the source folder which is to be synchronized
- -r or --fld_sync: Path to the replica folder
- -l or --fld_log: Path to the folder in which the logfile will be created

optional parameters:
- -i or --interval: Interval of synchronizations in minutes, defaults to 1 minute
- -d or --duration: Duration of synchronizations in minutes, defaults to 1 day (after which the script is finished)

Synchronization periodically via a task in windows task scheduler: The script sync_task_v2.py has 5 inputs of which 3 are required:

- -s or --fld_src: Path to the source folder which is to be synchronized
- -r or --fld_sync: Path to the replica folder
- -l or --fld_log: Path to the folder in which the logfile will be created

optional parameters:
- -i or --interval: Interval of synchronizations in minutes, defaults to 1 minute
- -d or --duration: Duration of synchronizations in minutes, defaults to 1 day (after which the task stops being triggered, but still exists)
