CrashPlan is a great way to backup your ZFS server, here’s a quick install recipe for OpenIndiana:
Download the Solaris CrashPlan client from here: http://www.crashplan.com/consumer/download.html?os=SunOS
Move the file to /var/spook/pkg then run…
# sudo pkgadd
(follow the prompts, do what’s obvious).
Setup Crashplan service:
# svccfg import /opt/sfw/crashplan/bin/crashplan.xml
# svcadm enable crashplan
Obviously you’ll want to move the backupArchive folder to your ZFS storage pool. I like to move the entire crashplan folder to the pool and create a symbolic link to it so I’ve got a backup of the CP config files…
# svcadm disable crashplan
# mv crashplan /tank/crashplan/opt/sfw/
# ln -s /tank/crashplan/opt/sfw/crashplan .
# svcadm enable crashplan
