Colocando mais lenha na fogueira: No ports existem alguns softwares de replicação para serem usados em "userland", segue alguns:
# cat /usr/ports/sysutils/fusefs-chironfs/pkg-descr Chiron FS is a FUSE based filesystem which implements replication at the FILESYSTEM LEVEL like RAID 1 does at the DEVICE LEVEL. The replicated filesystems may be of any kind you want the only requisite is that you mount it. No need for special configuration files, the setup is as simple as one mount command (or one line in fstab). WWW: http://code.google.com/p/chironfs/ # cat sysutils/p5-mogilefs-server/pkg-descr http://en.wikipedia.org/wiki/MogileFS: MogileFS was created by Danga Interactive for use with LiveJournal. It is similar to the Andrew File System in its design goal. It is different than a traditional filesystem in that the user has to access files via an API. However, it's possible to implement the file system in user space using FUSE, or a similar package. MogileFS enables horizontal scaling of storage across any number of machines. Files are replicated between machines according to customizable rules such that at any time a number of drives or machines could be lost without data becoming unavailable. It is designed for high volume applications, such as high traffic websites, to spread storage across cheaper machines without relying on technologies such as NFS.
