Copying locked files

P: n/a
I am running into one really big problem.

I wrote a script in vb.net to make a copy of folders and subfolder to
another destination:

- in 'from.txt' I specify which folders to copy
- in 'to.txt' I specify where to copy it
- After I read content of 'to.txt' I create one more subfolder named
by current date and thats where everything gets to be copied
When I execute the program, it starts to copy my folders and
everything runs just fine.

Here is when the problem occurs:
I am trying to backup this way a folder, where some files are being
used by our network users.

Once my program gets to the point that it wants to copy file which is
being currently used, it crashes.

I can't figure out how to amend my program to make a copy even that
the file is locked or being used by someone.

Can you help me?

P: n/a
Do you really want to be reading a file that is in use, you will have no
idea what state the file is in. What I've done in these cases is to wrap in
a try... catch and log the fact the file could not be backed up. I don't
think there is a way for the Copy method to do this. You would have to open
up the file with a FileStream object and copy it byte by byte...

Hope it helps.

Martin,

I looked at your program, however I thought that the question itself is
clear for me. In my opinion can you for that you at the moment only use a
try and catch block

something as in pseudo
\\\
If file.exist(path)
dim notfree as boolean
do while notfree = false
Try
readfile
notfree = true
catch
threading.thread.sleep(10000)
free = false
end catch
loop
end if
///

A little bit changed as I thought provided by Herfried, K. Wagner to this
newsgroup
(You have to create an escape of course when somebody never stops using it)

I hope this helps?

Thanks for all your answers.
So apparently, if file is in use it cannot be copied.
I wonder how V2i backup or Norton's new Ghost 9 do the backup off
everything on the drive, even that files are locked.
Byte by byte could be a solution. But, wow, that is one complicated
way.
Is there really nothing I can do?
I don't want to skip any files when copying. Or wait till file is
ready to be open. Some network users never close the application, so
how can I make a copy then?
There must be some way.

Byte By Byte isn't that complicated, you just open up a file, and write it
back out. Same idea that the Copy command is doing, you just need to do it
in a "share" mode.

I've haven't looked at Ghost 9 (I own Ghost 2003). Does it now to a copy
while Windows is running? Ghost 2003 makes you reboot to DOS.

Just curious?

Thanks for all your answers.
So apparently, if file is in use it cannot be copied.
I wonder how V2i backup or Norton's new Ghost 9 do the backup off
everything on the drive, even that files are locked.
Byte by byte could be a solution. But, wow, that is one complicated
way.
Is there really nothing I can do?
I don't want to skip any files when copying. Or wait till file is
ready to be open. Some network users never close the application, so
how can I make a copy then?
There must be some way.

Wow! The last time I worked with Norton's Ghost was when it was available
in version 5!

If a file is locked, there is AFAIK no chance to read it except with a
custom I/O driver.

Yes new Norton Ghost and V2i as well, can do this while windows
running.
Tested it myself.
But they do the image of the whole drive. There is no way of backing
up just certain folders.
That is why I need to do this program.
Tell me, there is a way of doing this.
Thanks.

Sounds to me like you need a professional backup program.

Q: Are open files protected by Backup Exec for Windows Servers ?

A: Yes. The Backup Exec Advanced Open File Option ensures that files
on local or remote servers are protected even while in use. This option
handles open files at the volume level and is seamlessly integrated into
Backup Exec. This advanced technology helps enable 100% application
availability and 100% complete backups.

Greg,
I do not need another software, I want to write this in VB.NET.
Or I'd like to know from someone with great knowledge of VB.NET that
it's impossible task. Then eventually I will go and try to write this
in different language or as you mentioned, buy a software.
This shouldn't be too hard.
Come on guys.
M.
