shutil.copy2 error

[Horse]

I've written a python script that copies a nightly Oracle backup file
to another server.  Every couple days, the script fails with this
error message:

Error copying Q:/Oradata/GISPROD/Backups/3UISN35R_1_1 to s:/gisprod/
backups/3UISN35R_1_1
[Errno 22] Invalid argument



Here's the code for the function I'm running.  The path names are all
correct, and it works *most of the time*.  It only fails about once or
twice a week.  Anyone know where I can get more info on this "errno 22
invalid argument"?


def CopyNewFiles(SOURCE_DIR, DEST_DIR):
global STATUS
try:
os.chdir(SOURCE_DIR)
for x in os.listdir(SOURCE_DIR):
int_time = os.stat(x)[stat.ST_CTIME]
str_time = time.ctime(int_time)
if datetime.date.fromtimestamp(int_time + 0.00) >
YESTERDAY:
try:
DEST_FILE = os.path.join(DEST_DIR, x)
logfile.write(" Copying " + SOURCE_DIR + x + "
to " + DEST_FILE + "\n")
logfile.flush()
if not os.path.isfile(DEST_FILE):
shutil.copy2(x, DEST_FILE)
else:
logfile.write("File exists.  Skipping.
\n")
logfile.flush()
except (IOError, os.error), why:
logfile.write("\n\nError copying " + SOURCE_DIR +
x + " to " + DEST_FILE + "\n\n")
logfile.write("\n" + str(why) + "\n")
logfile.flush()
STATUS = "FAILED"
except:
logfile.write("\n\nUnhandled error in CopyNewFiles\n\n")
logfile.write("SOURCE_DIR = " + SOURCE_DIR + "\n")
logfile.write("DEST_DIR = " + DEST_DIR + "\n")
logfile.flush()
STATUS = "FAILED"

Thanks for the ideas, I will look into if there is anything else using
these files (maybe a system level backup they hadn't told me
about??).  Otherwise, these files are perfectly valid, I can go back
on the ones that error and manually copy them by hand to the
destination folder.  I should've mentioned earlier, but this is
running on a windows 2000 system, and the destination folder is a
samba share on a Linux server.

OH MY GOD! HUMANS HAVE ORIGINS IN THE DEVONIAN!

[HORSE SHIT]

THRINAXODON ONLY HAD THIS TO SAY:

"I..I...I...Can't believe it. This completely disproved Darwinian
orthodoxy."

THE BASTARDS AT THE SMITHSONIAN, AND THE LEAKEY FOUNDATION ARE ERODING
WITH FEAR.

THRINAXODON WAS SCOURING ANOTHER DEVONIAN FOSSIL BED, AND FOUND A
HUMAN SKULL, AND A HUMAN FEMUR. HE ANALYSED THE FINDS, AND SAW THAT
THEY WERE NOT NORMAL ROCKS. THESE WERE FOSSILIZED BONES. THEY EVEN HAD
TOOTH MARKS ON THEM. SO, THRINAXODON BROUGHT THEM TO THE LEAKEY
FOUNDATION, THEY UTTERLY DISMISSED IT, AND SAID, "We want to keep
people thinking that humans evolved 2 Ma." THRINAXODON BROUGHT HIS
SWORD, AND SAID, "SCIENCE CORRECTS ITSELF." RICHARD LEAKEY SAID, "That
is a myth, for people to believe in science." THRINAXODON PLANS TO
BRING DOOM TO SCIENCE, ITSELF.



THRINAXODON IS NOW ON REDDIT
