I had a few questions about ReFS since documentation is not very good. Directed at anybody with experience using it.
Objective - want checksumming of files for alerting of present bitrot. ReFS has file integrity streams that in theory do exactly this. I have backups, so I don't care for redundancy. I just need to know which files are bad ASAP.
Setup - ReFS drive is an external drive connected to windows 11 (pro). (Using another pc with enterprise to format.)
A couple questions/concerns
#1- ReFS "salvage" feature. It removes files from the namespace if they are corrupted and can't be repaired (which is always on a single disk). Is this tied to the -Enforce option being on for integrity streams or is having integrity streams enabled sufficient for this to happen. I absolutely do not want files to disappear (acknowledging removed from namespace != deleted) without me knowing.
#2 - I noticed that data integrity scans are not enabled in task scheduler (and contradicting the documentation, has triggers set to run every day instead of every 4 weeks, though it's disabled.) There also seem to be three different options
What's the difference between the first 2 apart from the triggers? Does this scan even work in windows 11 non server?
