Some stuff was accidently deleted of a samba share from windows. Now I understand that this has nothign to do with windows as samba was on a linux box and the shares were just mounted on the windows box. Now that the stuf has been deleted, I was wondering if there was any way to recovre them. I have experienced this before unsucessfully.
Also, whats the best way to deal with tihs situation. Maybe this has to be done on windows such that nobody is able to delete anything at all???
Comments /Info please ??????????????

Also, how do I set up the samba configuration file such that stuff that is exported on windows can be manipulated in every other way possible except for deletion.
The samba file shares are exported to windows machines and each user has a folder which only s/he can delete. So, now I want to remove the option which gies the user the right to do so. Here's the share definition for the samba folder that is exported. Where do I set the (no-delete option for everyone).


#============================ Share Definitions ==============================
#[homes]
#comment = Home Directories
#browseable = no
#writable = yes

[samba]
path = /home/csl1/Samba/samba
comment = CSL Windows Data Server
#valid users = @csl-users
writable = yes
guest ok = no
wide links = yes
#force group = csl
veto files = /*.mp3/
force directory mode = 775
dont descend = profiles netlogon

# Un-comment the following and create the netlogon directory for Domain Logons
[netlogon]
comment = Network Logon Service
path = /home/csl1/Samba/netlogon
guest ok = yes
writable = no
share modes = no
#browseable = no

# Un-comment the following to provide a specific roving profile share
# the default is to use the user's home directory
[Profiles]
path = /home/csl1/Samba/profiles
browseable = yes
#guest ok = no
writable = yes
create mode = 0700
directory mode = 0700

# NOTE: If you have a BSD-style print system there is no need to
# specifically define each individual printer
[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
# Set public = yes to allow user 'guest account' to print
guest ok = no
writable = no
printable = yes

Thanks a bunch.
