This app accepts hot folder and backup folder paths, backing-up any file that is created or modified in the chosen folder.

App is written in Go.

It uses one direct 3rd party library: fsnotify. This library provides cross-platform filesystem notifications, it is widely used and maintained.

Easiest way to build executable is to use provided Makefile job:

make build

Then run executable with arguments for hot and backup folders:

./out/backupper --in={hot_folder_path} --out={backup_folder_path}

Application will save state of folders paths and log view filter. On subsequent start, arguments are not required - previous state would be used.

Demo job is provided in the Makefile, it will build and run executable in 'tmp' folder and provide paths to 'hot' and 'backup' folders inside it:

make build_run_demo

To demonstrate states persistence, there is another job in the Makefile, it is supposed to be run after 'build_run_demo' is stopped. It does not provide folder paths, so application load previously used paths:

make second_run_demo

Cleanup after building/running application:

make clean

Run tests:

make test

On application start it will prompt for log viewer filter information.

First prompt will allow user to enable/disable log viewer.

Subsequent prompts will allow user to configure filter. On second application run it will ask to reuse previous state.

Filter is built for date and filename. If user leaves empty prompt input, it will disable appropriate filter.
