I should have qualified that -- when I used ZFS only as a volume manager 
and file system, it was not much harder than md and ext4.  You could put 
a GPT partition scheme on the external USB drive, create one large 
partition, encrypt the partition (optional), put the partition into a 
ZFS pool, create one filesystem inside the pool, and set the 
'mountpoint' property on the filesystem (ZFS does not use /etc/fstab). 
Use the filesystem like any other Linux filesystem.  If any bits rot, 
ZFS will detect them.  Do a "scrub" periodically (e.g. monthly).

I did some more searching for ZFS on Wheezy.  See the second FAQ item:

     https://wiki.debian.org/DebianWheezy


Add this line to /etc/apt/sources.list:

     deb http://archive.debian.org/debian wheezy main contrib


Then run these commands:

     # apt-get update

     # apt-cache search zfs


Look for "zfs-dkms".
