openzfs VS btrfs

Heads up, installing both WinBTRFS and OpenZFS on Windows may have problems:

"Win OpenZFS driver and WinBtrfs driver dont play well with each other"

https://github.com/openzfsonwindows/openzfs/issues/364

I tried it a few months ago and ReFS ate my data. No indication of why in event logs or SMART data. It had IsPowerProtected set because I have a UPS and I had a unclean restart, I would expect it to lose data, but not to corrupt the filesystem metadata. I had a backup of the data but wanted some recent changes. Refsutil (the official Microsoft tool) didn't help because it has not been updated for the newest ReFS version. I couldn't read most files because I had integrity enable and files failed the check. Hetman's Data Recovery was able to recover most of the data. In later testing I found out that IsPowerProtected is just very unsafe. I have since put some time into testing and sometimes fixing https://github.com/openzfsonwindows/openzfs , it is not ready for use yet, but it is making great progress.

Windows lacks support in the same sense that Linux lacks support; there are external projects implementing it for both, though I believe the Windows port is less polished. (Some people are running it in production, though...)

This is really cool and speaks to the modularity of the Windows file system stack. I love projects that customize Windows (working against its closed-source nature).

There’s an OpenZFA port to Windows[0]. I wonder if my hopes of having ZFS on Windows (including the boot drive, because I would love to be able to snapshot and rollback) would actually be possible.

*cough* it can, but... no idea how well it works but it seems a bit hacky.

If you have not used it, maybe the native ZFS port for windows could be an easier solution.

Theoretically ZFS is ported to windows, but I heard that it is not really stable yet.

I did use the packages provided here: https://github.com/openzfsonwindows/openzfs/releases/tag/zfswin-2.1.6rc2

Can this be used? I knew ReactOS would use it natively.

I loose out on BTRFS snapshotting and subvolumes then. And if you look at winbtrefs it’s more than a hobbiest project. It has quite active development progress constantly https://github.com/maharmstone/btrfs

I've installed the WinBtrfs driver on Windows, which supports read/write support for Btrfs partitions.

Install WinBTRFS so Windows can read the file BTRFS file system.

I don’t know if that tool allows to write but this GitHub page https://github.com/maharmstone/btrfs seems mature enough. I am still unsure to trust it because I could bork my SSD and files

https://github.com/maharmstone/btrfs scroll down to mappings and that *should help with sharing things between both OSes.
