command to compress a folder in a Linux VPS(ubuntu) ?

rahulks

Anyone knows?

i want to download www(folder) inside /var

Mon5t3r

tar czf varwww.tar.gz /var/www
tar cjf varwww tar.bz2 /var/www

?

rahulks

I should type " tar czf varwww.tar.gz /var/www " right?
why two cmds? diffrent formats?

jh

The first creates a tar.gz, the second is an alternative format: .tar.bz2.

There's also

zip -r archive.zip /var/www

for a .zip file

when i try

zip -r archive.zip /var/www

jh

yum -y install zip

apt-get install zip

PS (For future readers). ZIP is limited to ~4GB of compressed data. tar would be a better option for larger files.

And bz2 offers a bit better compression than gz.

there's also plzip and pbzip2 / lbzip2 for speed + compression ratios http://vbtechsupport.com/1614/

If the folder is large, bz2 takes quite a bit longer to compress than gz.

Not so much anymore, most linux OS switch to zip64 once it is bigger than 4GB. With zip64 it is ALOT more.

try lbzip2 easily 4-8x times faster than bz2 if you have more cpu threads to support lbzip2 But yes still slower than gzip and pigz

Use rsync.

Do you know if zip64 is slower than regular zip?
