Explanation

ZFS Deduplication Property Solaris Express Community Edition, build 129: In this Solaris release, you can use the deduplication property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored and common components are shared between files. You can enable this property as follows: # zfs set dedup=on tank/home
