TAR – Tape Archive (application/x-tar)
A common archive format used on Unix-like systems. Generally used in conjunction with compressors such as gzip, bzip2, compress or xz to create .tar.gz, .tar.bz2, .tar.Z or tar.xz files.
# tar -cvvf foo.tar foo/ –exclude=”/home/svnlabs”
# tar -cvzpP –file=/home/backup.tar.gz –exclude={/dev/*,/proc/*,/sys/*,/tmp/*} /
tar work with directory “/” except for /dev, /proc, /sys, /tmp 🙂
