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.
I think that is not so unreasonable for the features you are getting. I wonder if it would be possible to put the file system data structures on an SSD? I also have read that it is a good idea to use ECC memory on such a fileserver, but that's really true of any computer. Undetected memory errors will cause data loss.
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.
I am inclined to agree. If I was setting it up for a serious production environment, I would bite the bullet and run Solaris as well.
When its good, its very good, when its bad, its reformat and restore from backup time...
We'll maybe I'll live with backuppc for now.
