I'm not sure there is. I'm sure there are some tapes that you can query, but I can't find much out about that. > I realise that I could compress the data before it goes to the tape but the > overhead in CPU and time will reduce my backup window too much and therefore > is not an option That's not obvious. The data rate you show is pretty low, less than 10M/s, which is only a fraction of what any LTO tape can take. Pretty well any worthwhile CPU ought to be able to compress the data at that rate -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
