:We've used just over 1 TB to completely archive 37 servers. Daily
:snapshots use <5 GB each. This particular server (9 TB) should last
:us for a couple of years. :) Even after we get the full 75 remote
:servers being backed up, we should be good to keep at least 6 months
:of daily backups online. :)
It is a far cry from the tape backups we all had to use a decade ago.
These days if the backups aren't live, they are virtually worthless.
:Or, you can use the mirror feature to mirror your backup server to an
:offsite server. :) That's what we're planning on doing with ours,
:using the "snapshot send" and "snapshot receive" features in ZFS.
Ah, yes. I should have mentioned that. It is an excellent way to
bridge from a non-HAMMER filesystem to a HAMMER filesystem. At the
moment my off-site backup system is running linux (I'm stealing a 700G
disk from a friend of mine) so I can't run HAMMER, but hopefully some
point before the 2.2 release I'll be able to get my new DFly colo server
installed in the same colo facility and then I will be able to use
the mirroring stream to backup from the LAN backup machine to the
off-site backup machine, HAMMER-to-HAMMER.
:There's lots of great work going on in filesystems right now. It's
:nice to see the BSDs up near the front (FreeBSD with ZFS, DFlyBSD with

I think the linux folks have wandered a little, but it only goes to
show that major filesystem design is the work of individuals, not OS
