Hi all,
I have a storage server that holds one million of images with well
structured directory structure such as
/data/user1/2008/09/12/image1.jpg
/data/user1/2008/09/12/image2.jpg
...
/data/user2/2009/01/01/image1.jpg
...
I want to copy them to the /data2 directory in the same server on
another disk partion.
I want to keep the directory structure and `chown` && `chmod` the
directories and files,much like doing a `cp -rf /data /data2 &&
chown -R sysuser:sysuser /data2 && chmod -R 755 /data2`.
File::Find maybe an option.
Is there somebody who have some suggestions?
If I do a `cp -rf /data /data2 && chown -R sysuser:sysuser /data2
&& chmod -R 755 /data2`,how much time maybe taken to finish the
job?(The images are about one million in count and 250GB in size
totally).
Perhaps I am missing something completely obvious. If not:
Why-oh-why do you want to use Perl do perform such a task?
Use dump/restore (which I can't recall a cli sequence for off the top of
my head), or rsync:
tar can also be used to copy a hierarchy of directories and files.
You pipe the output of one tar into the input of another. From 'man
tar':
To move file hierarchies, invoke tar as
tar -cf - -C srcdir . | tar -xpf - -C destdir
