Hey guys, the reason you can't use shadowspawn with USB flash drives is because the source drive must be an internal disk OR report itself to Windows as a local disk rather than a flash drive. Shadowspawn basically uses the Volume Shadow Copy Service in Windows7 (VSS) and below are the requirements for the VSS to function:
  • Microsoft Windows XP with SP1 installed. All subsequent versions of Microsoft Windows include VSS.
  • 32-bit (x86) or 64-bit (x64) version of Microsoft Windows installed
  • The files you want to backup must reside on a NTFS formatted partition. An internal FAT32 drive can be backed up only if you also have an NTFS partition available.
  • The files you want to backup must reside on local disks (or external hard drives that report themselves to Microsoft Windows as local disks).

So yeah, kind of a bummer that it won't work for USB flash drives. Good news however is that you can still use robocopy without shadowspawn to backup those drives.

yay, i still haven't used shadow spawn! wheee.gif

Thanks for the info smile.gif

Bummer. But at least robocopy works. I see an update needed smile.gif

Hey Sean, I just noticed that all of the places where we have code samples in this thread, the new forum software is making two backslashes appear when there is only one. The solution to this is to hit edit on your posts where it has the double backslashes and then just hit save and it should fix the problem. Don't want anyone to have trouble running this script because of the double backslashes! tongue.gif

Alright, thanks. smile.gif

I think my friend is having an issue with something, I told him to post in here about it, but he hasn't so far. lol

hey i used your backup guide and it works great. One little problem though. The only way i can access the file is through checking the folder options and disabling hide windows protected files. Is there anyway around it?

Have you guys tried any of this on XP?

You can be the first smile.gif

I'm setting up the machine right now, so when it's ready I'm going to try it. Though I'm just curious about robocopy, since you guys mentioned it comes with Windows 7.

You should just need to download it from the link I have in the guide, once installed you should be set.

So far no luck with using this in XP. Will get back to it, as there's something else I wanted to throw out there.

From my tests, it doesn't look like it updates the files if it's a new file, it only updates it if it sees that there's a difference in the files. Thus you can end up backing up old files rather than new ones. Here's the scenario:

I created three folders on my desktop named 01, 02, and 03. In side folder 01, I placed a text file that said "Folder 1". I ran this batch file:
Code:
shadowspawn "C:\Users\Zoidberg\Desktop\01" Q: Robocopy Q:\ "C:\Users\Zoidberg\Desktop\02" /E
shadowspawn "C:\Users\Zoidberg\Desktop\02" Q: Robocopy Q:\ "C:\Users\Zoidberg\Desktop\01" /E
shadowspawn "C:\Users\Zoidberg\Desktop\01" Q: Robocopy Q:\ "C:\Users\Zoidberg\Desktop\03" /E
shadowspawn "C:\Users\Zoidberg\Desktop\02" Q: Robocopy Q:\ "C:\Users\Zoidberg\Desktop\03" /E
shadowspawn "C:\Users\Zoidberg\Desktop\03" Q: Robocopy Q:\ "C:\Users\Zoidberg\Desktop\02" /E
shadowspawn "C:\Users\Zoidberg\Desktop\03" Q: Robocopy Q:\ "C:\Users\Zoidberg\Desktop\01" /E

I set this up to see if files would be exchanged from all three folders equally. Once done, my text file was in all three folders. No problem.

I opened up the text file in Folder 02, and edited to say "Edited Folder 2 text." I saved it and ran the same batch. I open up my test files in all three folders afterwards to find that it says "Folder 1". I thought I might have did something wrong, so I tried it again but this time I opened the file inside Folder 03. This time I edited this file to say "Edited Folder 3 text". I ran the batch and the text files in each folder now reads "Folder 1".

My conclusions:

1. Obviously the order of the commands count.
2. More importantly, it doesn't just back up the files that are updated. It updates it if it sees that there's a difference in the files, even if it was older. Thus it will replace files from the source to the destination if there is any difference in the files, but note that the files will get moved from the source folder. Tough lesson to learn, as this means I have overwritten files I did not intend to.
