snapraid-helper VS custom-scripts

Alternatively to running snapraid.exe directly, you might wanna consider snapraid-helper - a tried and tested wrapper, written in Powershell, that does additional things: disk error checks, a pre-diff check, and can email notifications.

Known about this issue for some time and managed to resolve it with my own setup, but neglected to update my repo at https://github.com/droolio/snapraid-helper (not the original author, but AFAIK this is the only place which has the fullest commit history, from when it was hosted on Codeplex).

This is an incredibly useful script borrowed from droolio/snapraid-helper: PowerShell helper script for SnapRAID (github.com) which references a configured .ini and allows you to use task scheduler to handle snapraid tasks.

Snapraid takes some configuration in files (see the manual), it doesn't really have a GUI, and doesn't keep a parity at all times. You have to (manually or by creating a task) start a sync and/or scrub to update your parity file at a particular time, so it is more suitable for data that doesn't change often, like a media library, you most likely only modify/add/delete a few files per day. But the metadata for your library is best left out of the pool, that can change more often. For creating the sync/scrub tasks on Windows, there's also a Powershell script that I'm using: https://github.com/droolio/snapraid-helper.

If you're after a good Windows script, snapraid-helper has proven quite reliable for me.

This is what you want. Just customize it for your data and parity drives and then you can setup up a task to run it every night with task scheduler.
