ARCHIVES

Demonstrate how to create archive files.

TODO:

• zlib, pigz (parallel gzip)
• provide timings and performance on large fake data generated files
• xz --long-help
• checksums for recovery?

Reason

It's useful to be able to quickly create and restore archives.

Tricks

# use file to identify the types of compression
file ./file.zip
> Zip archive data, at least v2.0 to extract, compression method=deflate

file ./file.gz
> gzip compressed data, from Unix, original size modulo 2^32 231151

file ./file.tar
> ./file.tar: POSIX tar archive
