The presentation will give you everything you know to get up to speed with btfrs, why you should want to trust your data to btrfs, how it offers a lot of what ZFS offers without the licensing problems, as well as best practices for using it. I will go into: - the basics of administration of a btrfs filesystem - How btrfs, swraid, dmcrypt, and lvm fit or don't fit together - how to work with a single storage pool and create all your partitions from it without having to ever resize them, or require LVM as a slow and somewhat unreliable block layer. - how to have virtually as many snapshots as you want and why you really want this - how to do very efficient block level backups of changes only and much faster than rsync ever will - how those block backups can be used to deploy OS upgrades at the file level like I explained in my talk on how Google maintains its many servers last year.
