Now I thought about a way to safely backup a MySQL or other database - without long service interruption: - Tell DB to turn itself into consistent state and freeze there - sync / btrfs filesystem sync ; fsfreeze -f /mountpoint - btrfs subvolume snapshot - fsfreeze -u /mountpoint
Hmm, I don't think fsfreeze works properly with btrfs? -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
