Phoronix: Btrfs Send Stream v2 Support Queued Ahead Of Linux 5.20

The Btrfs send/receive functionality allows for generating a stream of changes between two sub-volume snapshots, which can be useful for efficient backup/archive purposes, among other uses. With the Linux 5.20 kernel is send/receive support for the new "stream v2" format...

Super useful for btrfs, especially since I had two total, unrecoverable, btrfs crashes in less than a year......Since then I stay away from it.

Still no native encryption like both ZFS and bcachefs have. Even Ext4 has native encryption today, albeit simple. Btrfs doesn't deliver.

Native encryption, stable RAID 5/6 support and more optimizations.

Huh? What were you doing?
I'm using it on my homemade backup/media server NAS for years (at least 6) without issues. Hard drives die from time to time, but I could always simply remove the broken drive and add the new one. Boring, as it should. Raid1 ftw

Me too. Around 4 Years now. Still the same drive pool just added 2 years ago some drives for more space. btw scrubing also finished allways without error.

how long is this ago? It is also quite likely that the controller was not working correctly? CAn find the link anymore but there was a article about btrfs done by a fs expert of facebook telling that btrfs was the only filesystem showing that there was a hidden corruption by hardware. It was so subtile that all the other systems havent noticed it. For him it was the point to start taking btrfs sireously.

Would be nice, I agree, as it would simplify the setup. But is it as secure as block based encryption? If I'm not mistaken you still leak metadata like file sizes.

[karolbe]

No, it was not a controller or anything like this. I switched to ext4 on that drive and had no issues since then. It was around ~2 years ago. Funnily enough, in January someone switched to btrfs even though I told him to stay away from it had a total FS crash as well just after 4 months of using it :-)

This should simplify my backup setup (currently involving taking full snapshots, and just using rsync as delta tool)
