One place where ReFS is rather decent is "reflinks" - that's where identical blocks are stored once and in the background the rest are simply links to the one block.
That is rather useful in backup systems.
XFS also supports reflinks amongst other things and is way older than ReFS and hence considered out of beta (which ReFS isn't, by me)
I don't trust data to RefS yet - its a fun project that will no doubt prove itself one day. For now, Windows boxes run NTFS and Linux runs ext4 or XFS.
- Gabrys1 3y agoWhat happens if the very important directory you copied 11 times (just to be sure) ends up producing the same block and doesn't indeed get duplicated as you expected? And now, that block gets corrupted...
- defrost 3y agoBack in the day if I copied (geophysical air) survey data 11 times and put all the copies in the same walk in fire proof safe (in the hanger), that offered no real additional security in the event of a direct hit by an aircraft and explosion while the door was open. If you're going to make 11 copies, they have to go to different physical locations, different devices at least, geographically different places to be sure, or it's pointless. In this instance, block de-duping on a single device makes sense .. expecting mutiple copies on the same device (with or without duplicat block reuse) to offer any additional safety does not.
