# RAID FS

A basic RAID 0 implementation that takes data written to one directory and writes it to multiple directories while sharding the writes.

The goal would be to use a performant disk for the main writes, while backing up the additional writes to less performant NFS disks.

## Usage

`npm start` by default will watch for changes in `input_dir` and write them to three `output_dir_x`s.

  - writes update the data in the output directory

  - deletes remove the data in the output directory

  - moving a file constitutes a delete plus an update and is handled appropriately. 

`npm start --restore` will load data from the output directories and assemble it into the input directory.

## Configuration

`npm start -f path/to/config.json` will allow you to change the parameters of which file constitutes input, output, and whether or not to erase the `inputDir` on start.
