Anyone know how to properly set up Snap Raid sync / scan / repair?

[Tengis]

Title pretty much says it all. Ive been running SnapRaid for a while but I havent ever properly set up the scanning and repairing portion of it. At this point, I pretty much use it in case of a drive failure and nothing else.

Ive read through plenty of tutorials when I first set it up but I never really sat down and figured out what settings would put the least amount of wear on my hard drives while also protecting against data corruption and such.

On linux I have a script that automatically runs a sync and a scrub if no files were deleted.

It's basically this script: https://zackreed.me/updated-snapraid-sync-script/

I have it scheduled to run every saturday night at ~4:00AM

Outside of that I somewhat randomly log on and do a

snapraid diff

then briefly look at the list

then
snapraid sync

and if there is time / know the tuners are not going to be very active I do a
snapraid scrub

I just did a sync 20 minutes ago..

My status looks like this

snapraid status
