splittar allows you to create one or more tar
files from a set of data where each of the
generated tar files is less than a specified
maximum size. Each tar file is a proper,
self-contained tar file. Other methods of backing
up data to removable media requires a tar file to
be split, making one of the tar file useless
without the others. splittar was written to back
up large amounts of data that span multiple DVDs
while allowing for each DVD to be useful on its
own.
