It would make me less afraid to make a mistake while using my computer. I *think* you would have to custom build templates using btrfs, but I have no idea if that would work - I'll try and report back. When I'm making significant changes then I make liberal use of qvm-clone: then I may archive off, but more usually just throw away the clone if I'm happy. (On the rare occasions that I work with Windows qubes I do this a lot.) Yes. If you have Btrfs in dom0 then you already have those features at the VM level at least. And I would recommend against putting Btrfs on top of Btrfs, as its more CPU intensive. For those who have the default LVM in dom0, Btrfs in appVMs is a better prospect. But since LVM also has snapshots, to me the only two overriding reasons to use Btrfs this way is for compression (Btrfs has Zstandard now!) of things like databases and email archives; and also for its integrity checking. -- Chris Laprise, tas...@posteo.net https://github.com/tasket https://twitter.com/ttaskett PGP: BEE2 20C5 356E 764A 73EB 4AB3 1DC4 D106 F07F 1886 -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

I have btrfs set up for dom0 and I'm using the refilnk driver, but my appvms themselves seem to be ext4? Where would I even set this?

Looks to me that is has support for functioning in appvms., But I can not test currently On Friday, December 11, 2020 at 7:36:59 PM UTC-5 keyandthegate wrote: > I want to use btrfs for the snapshots feature in my appvms. > > I know Qubes supports btrfs for dom0: > https://github.com/QubesOS/qubes-issues/issues/2340 > > Does Qubes support using btrfs in individual appvms? > > If not is there some other way I can get snapshots?

Re: [qubes-users] Re: BTRFS?
Thanks Rusty. People should be aware of this. I think I did reclaim all space but fiddled too much with the settings. Anyway, it was a good excercise, I learned about btrfs, LUKS and dracut, that wouldn't happen otherwise. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Re: BTRFS?
I have root, home and var as subvolumes on a btrfs volume. I intended to create snapshots before updates. The tricky bit was to put it on a LUKS partition as somehow the installer encrypted only the swap partition. Maybe it was my fault, not sure now. Anyway, if you do it check that it is on top of an encrypted partition. If not, you're in for some practice in manipulating btrfs volumes and manual setup of dm-crypt ;) -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
