I've got a drive on our network that I make backups to every week by dropping to a command prompt and just doing an xcopy /s. This week I got a new drive and decided to try out Server 2008 64 bit. Today I started to make a backup to the removable drive and ran into a "Insufficient disk space" error message. I looked at the drive and it has some 212 gigs free and I'm only copying about 200 megs. I used windows explorer to copy and it worked fine without any errors. I tested it from the old drive(XP SP3 32bit) using xcopy at the command prompt and it worked fine. I made aXP SP232bithyper-v and ran the same test and it worked fine. I did the same operation to a different share on the network and it worked fine. My final test was using powershell with -recurse and -force and it also worked fine. What could be wrongwith xcopy and Server 2008 64 bit across a network to this particular device? It seems to hit a subdirectory and gives the insufficient disk space error. Why does explorer and powershell not have a problem while xcopy throws this error? Here's some captures of what I'm doing, when it works correctly I stop it as you get the drift. Here's what I get with xcopy: C:\development\JobSlip>xcopy c:\development\jobslip\*.* u:\Jason\Development\jobslip\ /s/cOverwrite U:\Jason\Development\jobslip\00000500.tpf (Yes/No/All)?

Aarrgh, you have effectively broken any manual back up routine I have. If I use xcopy there is a known "insufficient disk space" problem with large fikle names. I just tried moving folders from one drive to the next and get "The folder already exists, try renaming it" The folder exists, try renaming it? The programmer who created that error message should be shot!!!! Of course the folder may already exist, it is called backing up.... WHat is wrong with you peoplem, are you trying to force everyone to use your backup command, they even invented a cryptic ROBOCOPY instead of just fixing XCOPY. WTF!!!!! '
