Thread: fast file backup copy

-

i make several big folders copy/update usb memory stick backup everyday.
cp -r -u not favorite here, because takes long.

want copy new files changed 1 or several days ago, 1 or 2 times day.
bottom line want check file date , copy new files, usb flash memory,
make fast.

flow wil :
(1) read files in specified folders
(2) check if file date modified less 1 day,
(3) if no, skip, if yes make copy usb memory, maintaining directory structure.
(4) say, 3 files modified within 1 day 3 files copied, , directories has be
created in memory stick if not-exist.

help.

i think can use rsync that. more advanced cp backing or syncronizing. read more in man pages
code:
man rsync
