Do you mean when will people use it in a production environment, or when the experimental tag will be taken off? Those are two very different things. :) The experimental tag will probably be taken of somewhere in the 8.x lifetime, maybe 9.0 at the latest. That's my guess anyway. As for people using it in production environments, that's already happening. Personally, we use it in production for a remote backup box using ZFS and Rsync (64-bit FreeBSD 7-Stable from August, 2x dual-core Opteron 2200s, 8 GB DDR2 RAM, 24x 500 GB SATA disks attached to two 3Ware 9650/9550 controllers as single-disks). Works beautifully, backing up 80 FreeBSD and Debian Linux servers every night, creating snapshots with each run. Restoring files from an arbitrary day is as simple as navigating to the needed .zfs/snapshot/<snapname>/<path>/ and scping the file to wherever. And full system restores are as simple as "boot livecd, partition/format disks, run rsync". We're going to be adding a second identical backup box at a second remote location, and use the snapshot stream features to have redundant backups. We're also looking at using a similar box as a storage node for a virtual machine setup to create a disaster-recovery/fail-over site for all the systems in our main server room. And if that works, then we may use a similar setup to virtualise a bunch of the systems in the main server room. > Some of the tools build in to ZFS are very useful... Pretty much everything about ZFS is useful, except the name. :) Would have been better if they called it what it really is: the Zetabyte Storage Management System. It's so much more than just a lowly filesystem. Would probably solve a lot of confusion out there, IMO. -- Freddie Cash fjwcash@gmail.com
