Yeah there is all that, but in my case the data is also on the other machines in bits and pieces over several machines. Is yours only on the zfs server? An example here might be my photo/music collection. It resides on a windows XP pro machine where I have the tools I use to tinker with it. I back it up to the zfs server, but what is on the server is always a bit older (between backups) than the current version on the windows machine. So if the zfs server were to be beamed up to another solar system, I'd still have the latest greatest version on the windows machine. Anyway losing my entire house and several machines would leave me with much bigger problems than losing my photo/music collection. The shelter I'd be living in wouldn't have room for several machines. Nor would I have money to spend on such luxuries. > I make and keep off-site backups, formerly on optical media, moving > towards external disk drives. I'd be interested to hear about that. If you think its OT here feel free to write me direct (reader AT newsguy DOT com) I have something like a terabyte of data on the server. Man I'd really hate to try to back that up to optical media. Even to external hard drive would be a major time sync. Just backing up the 80 or so GB of Photos/music to optical medial is a nasty undertaking. I quit doing that when it grew past 15 gb or so.
