G.5 Exporting

There are a few automated ways to make full and partial (incremental) export versions of NEMO. Full exports are described here, partial and incremental backups in the next section. Again, it's best to be in NEMO's root directory:

    % cd $NEMO
The first possibility is to make a tar-file of the barebone source:G.8
    % make tarfile [FILE=nemo.tar] [SRC="src usr"]

With the optional FILE keyword (note the upper case!) you can save the tar-file in a directory in which you have write permission, just in case your name is not nemo. The default for FILE is nemo.tar in the current directory. It is currently about 10 Mb, if both the src and usr tree are exported.

It is adviced to compress the tar file, since in this case it saves a considerable fraction:

    % compress nemo.tar

The second possibility:

    % make tarbackup [BACKUP=nemo-fullbck.tar]
creates a complete tar backup image on a diskfile. this diskfile can be any device (file/tape) using the optional backup keyword. Note that this tar image will be very large, and is only handy to copy NEMO between identical systems, or make a backup of the whole system, since also binary files are backed up.
