Not ready for production … ReFS

So Resilient File System (ReFS) has been for 6 years so it should be stable for use with a backup drive, right?

Nope:

In the words of Wikipedia:

“Because ReFS was designed not to fail, if failure does occur, there are no tools provided to repair it”

When it does fail, you might just end up with a 2TB backup drive that you cannot read.

🙁

I found one third-party tool which does work, ReclaiMe.

Seems to work well.  If I need to pull data off this backup drive, I’ll purchase a license.
