what are you running on the server besides SBS?

Well a server reboot seemed to fix it up, my kernel paged and non-paged
memory shown in the task manager went right down and the robocopy worked.
It seems we can't get away from this "reboot the server every few weeks"
issue with the server grabbing more free memory the longer it is up...

What is the file format of the USB drive?
FAT, FAT32, or NTFS?

I'm again having issues with copying large backup files (45 GB+) to
external USB drives. Originally I had this issue with XCOPY but
switched to ROBOCOPY and it worked better, for a while. I think my
backup size has increased again so now it can't do the copy anymore,
here's the robocopy output:

So close, but yet so far ;-)

From what I've researched this has something to do with the size of the
paged memory poll, from a MS post:
-------------------
The CopyFileEx and CopyFile functions are used by
all of the standard file-copy utilities that are included with Windows.
Because these functions use buffered I/O, the maximum size of a file
that
you can copy depends on the amount of paged-pool memory that is
available
at the start of the copy procedure and whether the Physical Address
Extensions (PAE) kernel which allows access to memory above 4 gigabytes
[GB] is in use. With the standard kernel, 1 kilobyte (KB) of paged pool
is
required for each megabyte (MB) of file size that is opened for buffered
I/O. Because there are two files involved in a copy procedure, 2 KB of
paged pool are required for each MB in the source file.
-----------------

PAE is off, the server has 3GB of memory with plenty free with my paged
pool at ~200000K which by the formula above should allow up to 100 GB to
be copied. I also thought this wasn't an issue with robocopy, but
apparently it is as I see this in my event log when the copy fails:
------------
Event Type: Error
Event Source: Srv
Event ID: 2020
The server was unable to allocate from the system paged pool because the
pool was empty
--------------

KB259837 has some info on this for Windows 2000 and said it was fixed in
the latest service pack but apparently not in Windows SBS 2003 SP1. I
haven't put in SP2 yet (due to all the issues reported with SBS) but if
someone can confirm the issue is fixed then I can look at it.

I'm looking at KB304101 right now and it looks promising but I really
don't like messing with the pool sizes - anyone done this? Any other
ideas?

Thanks.
