Operating Systems Solaris How to backup when there is no tape available? Post 302893325 by DGPickett on Tuesday 18th of March 2014 01:34:26 PM

Compression of the output on a pipe (|bzip2 -9 >mount_path) helps with size and speeds network or other media speed. Before any media limits, generally compress is faster than gzip -1 is faster than gzip -9 is faster than bzip2 -1 is faster than bzip2 -9. There are a lot of tools out there:
Lossless compression - Wikipedia, the free encyclopedia
Compression Tools Compared | Linux Journal

Another way to get compression implicitly is to mount a zip as a file system. All writing to the zip, wherever it is, is compressed data, no pipes needed. https://code.google.com/p/fuse-zip/
