Try the thread "ZFS: unreliable for professional usage?" in zfs-discuss for further info, and read how SUN engineers agree to potential corruption without proper umount && export. Don't. Simply don't. At least not yet, as long as the recovery utility for the Überblocks is pending. Then test-test-test.
[i]Provided you've got enough space to create your redundant pools, ZFS is an awesome backup mechanism: 1: You can use zfs send/receive to copy data from your main pool to your backup pool. 2: You can use "incremental" zfs send/receive to only backup the changes. This is REALLY cool. 3: You can turn on compression on your backup pool to reduce the amount of space used. 4: Your data can be read on both SPARC and x64 as ZFS will do the endian translations for you. [/i] True, these are cool. Except, that backups in the first place need to be reliable. And pulling the drive after a umount, forgetting export, can irreversibly destroy all your data.
