I don't think you want to do this. Unless there has been a change of heart you can't rely on zfs receive accepting the zfs send from an old dump file. It is only guaranteed to work for the same version of zfs/the zfs tools. If there has been a change of heart then I want to know about it. > How can I do it in-one-command without intermediate file? > > The file ifself can be done using "zfs send tank/[EMAIL PROTECTED] > > /path/to/filesystem_snapshot.zfs" ?

Bearing in mind that I don't think you want to do this.. zfs send tank/[EMAIL PROTECTED] | ssh remote_server \( command_to_label_tape \; dd of=/dev/rmt/0bn \) > Of course, I can write to remote type using ssh using the command below > but I'd lile to see some kind of meaningful names on the tape: > > # zfs send tank/[EMAIL PROTECTED] | ssh remote_server "cat > > /dev/rmt/0bn" What kind of name do you want? Where do you want it. There are loads of ways. Starting from echo "tank/[EMAIL PROTECTED] `date`" > /dev/rmt/0bn upwards. > Thanks, Sergey Julian -- Julian King Computer Officer, University of Cambridge, Unix Support _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
