Hello!
While being on Linux I was using lvm2 volumes in raid-1 with ext4
filesystems and defining DLEs was quite straightforward.
Recently moved to Free(PC)BSD and everything is handled by ZFS, so I
wonder how to properly define my DLEs to regularly backup my desktop
machine to LTO-2 tapes?
Here is zfslist output:

Any hint?
I'm a bit confused by this article: http://www.tc.mtu.edu/~jfb/amanda-zfs.php
saying:
"To add ZFS filesystem entries to your AMANDA disklist, use the absolute
mount point. zfs list, used by the dump wrapper, indicates a mount
point of "legacy" in the case of root-on-ZFS, but AMANDA appears to
look for /dev/legacy if "legacy" is used in disklist, which causes a
host-check error and prevents the filesystem from being backed up, so
be sure to use "/" for the filesystem/device. The wrapper script will
take care of the conversion of "/" to "legacy".
Is it relevant only when using dump?
I plan to use gnutar and have root-on-ZFS...
Sincerely,
Gour
