Incremental Backup ??

[RJK]

Here's an easy one for all you batch file writers ! ?

I've just copied a biggish directory structure onto external USB hd drive
F:\ , using Windows Explorer ( 44.9gb's )

Source was internal hd D:\ with 31 root-directories, all dragged and dropped
into F:\D progs etc ...(to ext. USB hd

What's the best way to update the matching structure on external USB hd F:\D
progs etc ?

e.g. let's say I've added a sub-directory - containing files, or several
sub-dirs. containing files and further sub-dirs.and files, to the 31
root-dirs. on D:\ ...rather than wade through it manually:-

How can I, say, xcopy new additions to the structure on D:\ to F:\D progs
etc ...without having to overwrite to whole structure on F:\ again ?

regards, Richard

I'm guessing along the lines of using attrib to clear all the archive
flags from directories and files on source drive D:\ - (already copied to
ext USB hd), so that only new additions will have the archive bit set.
Then I can try to batch file the job but, VERY rusty - hence posting here


TIA

regards, Richard

Have a look at the output from xcopy /?. The /d switch will probably meet
your requirements.

Many thanks, ...in the end I settled for

@echo off

echo About to xcopy D to F with /m/e/f switches
echo note that /m resets archive bit on source drive files

....filenamed budtof.bat ...and desktop shortcut to it.

....tested it by dropping a couple of files in to root and sub-dirs. on D:\
and they get copied to ext. hd F:\ ...in the proper place / dirs. , so I got
pathanmes correct !!
....surprising what comes back after a bit of a struggle !

Thanks for the feedback. Keep in mind that there are several utilities that
can and will set/reset the archive bit. You might miss out on some files and
copy other files twice if you rely on it. I also recommend that you use the
/y and /c switches in order to make the batch file more robust.
