X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 02 Jan 2004 17:27:17 -0000 I'm finally getting to the point where my disk capacity massively outruns my tape capacity, so I'm thinking of converting to removable disk-only backup. I could just use Amanda to backup to disk, but I'm intrigued by Plan 9's archival filesystem where backups from (say Jan 1, 1999) would go in /1999/1/1 and you could just find the files directly rather than grovelling through dump files. Is there some standard tool for doing this on FreeBSD? You can't just do a direct copy cause this results in major disk space wastage so I'm imagining you need to use hard links or something to keep the size down. Thanks, -Ekr
