@k900:0upti.meK900Is the bcachefs room busted or something?17:10:01

@k900:0upti.meK900What do you use for backups on bcachefs?17:11:11
@raitobezarius:matrix.orgraitobezariusborg17:11:19
@linus:schreibt.jetzt@linus:schreibt.jetztborg I guess? It doesn't have send/recv yet, so "classic" backups are all you really get17:11:36
@linus:schreibt.jetzt@linus:schreibt.jetzt(though you can do backups of snapshots rather than of live data that's changing as it gets backed up)17:11:47
@raitobezarius:matrix.orgraitobezariusare snapshots considered as backups?17:11:50
@k900:0upti.meK900Can you make it do a snapshot?17:11:51
@k900:0upti.meK900I am mostly doing this for Conduit17:12:06
@k900:0upti.meK900Which is rocksdb17:12:08
@k900:0upti.meK900So I 100% need a snapshot17:12:12
@raitobezarius:matrix.orgraitobezariusi don't remember if you can mount snapshots17:12:18

are snapshots considered as backups?
if they're sent to a different pool (or equivalent thing) I'd say yes
17:12:43
@raitobezarius:matrix.orgraitobezariusthere's no pool concept yet17:13:01
@raitobezarius:matrix.orgraitobezariusi think this is a good time to get started on userspace CLI dev in bcachefs K90017:13:15
@hexa:lossy.networkhexa just hack your own tool 17:13:38

17:13:49
@raitobezarius:matrix.orgraitobezariusor just add the feature to the bcachefs CLI17:14:06
@raitobezarius:matrix.orgraitobezariusit's possible there's missing kernel APIs too17:14:13

yes
17:14:29
@raitobezarius:matrix.orgraitobezariusi guess you could do bcachefs subvolume snapshot $directory /.snapshots/$date/$theme17:14:47
