I am interested in backuppc, however from what I read online it appears that zfs is a very featureful robust high performance filesystem that is heavily used in production environments.
ZFS is very memory intensive on larger file systems. I believe they recommend on the order of 1GB ram per terabyte of storage for decent performance.
Personally, I would only run ZFS for any sort of production application on a Solaris 10/11 system where its natively supported, and then only with a support contract from Oracle.
When its good, its very good, when its bad, its reformat and restore from backup time...
