Hello Johan, I've read compression in BackupPC is much better than in ZFS. So is it not true? Should I definitely use compression in ZFS or is there any reason to use BackupPC compression? I've found BackupPC use zlib and ZFS use lz4 that is much faster, but doesn't have so good compression ratio. So... where is the truth? -- Patrik
