I've been using this command of late:

tar Bcf - dir1 dir2 | gzip -vf - | rsh user at host 'gunzip -vf - | tar 
Bxf - '

however, you say that these machines arent connected. (note the above 
can be used over ssh with ssh-agent). You can use tar, we have a zillion 
of those dat tape readers... use this:

tar cvf /dev/rmt0 dir1 dir2

to write to the tape. then of course you use:

tar xvf /dev/rmt0

tar (1) for more info. there is also cpio (1). note that gnutar uses a 
native gzip and bzip2. depending on how much data you have to move, it 
might be easier to use DLT or to physically move the disk. DAT is kind 
of small.
