is there a fastest option to cp files from dir1 to dir2?

i used cp to copy lots of small files (b/n 1M and 10M size; around 6G total) in Linux box. Di开发者_如何转开发dn't time it but since i am going to do cp again and again, can time it and be more specific later; but since the cp is not the major task, can't tolerate the time it's taking if there is a better option/choice/way. So, if there is a better way/option/method to do cp-ing (faster) files from one dir to another, be glad glad to try it out.

Thanks,

Either of tar/untar or rsync when told not to checksum will be faster, since they bulk-read files instead of handling them one-by-one.

You could try cpio, as that has a copy directory to directory mode.

use perl for fastest copy:

use File::Copy::syscopy;  # preserves OS specific file attributes
copy($foo,$bar) or die "cannot copy $foo to $bar: $!";  # always check for errors!

Try this just backup today's files:

find /home/me/files -ctime 0 -print -exec cp {} /mnt/backup/{} \;

Have you tried:

time (cd /usr/local/src/ && tar pcf - cvs.gnome.org) | buffer -m 8m -p 75 | (cd /mnt/tmp/src/ && tar pxf -)
