Refs or no refs

Should we start to use refs on ours filesystems?

Maybe, but not if any of the following true.

  • It’s a domain controller – Refs doesn’t support hard links among other things.
  • SQL Server – missing features like dbcc checkdb and snapshots.
  • HyperV – missing features like integrity streams on vhdx
  • It’s a bootpartition

Also there a few posts out there that have experienced problems with not being able to access refs-volumes after sudden power losses.

Why do we event want to use refs then?

  • Refs handles corrupted files better
  • Doesn’t need to use checkdisk anymore.

I think I’ll stick to ntfs for a little while longer…
