Creating Recycle Bin for Samba storage

I assume that you have successfully configure the samba server, if not, here is a quick and dirty samba configuration guide -  here

Samba is mainly used to share the files between Linux and windows and many times it happens that user deletes the file from the samba server and later wants to get back deleted files which is not possible with the default configuration of samba server.

The best option is to have a "Recycle bin" for every users on the samba server.
Here is an example of modifying the home directories of your users in samba configuration file

[homes]
comment = Home Directory
valid users = %S
browsable = no
guest ok = no
read only = no
vfs object = recycle
recycle:repository = RecycleBin
recycle:keeptree = yes
recycle:exclude = *.tmp, *.bak

The “vfs object” line calls in the plug-in that enables recycle bin capability.  On the other lines, you’re setting the name of the recycle bin directory, telling Samba to preserve the whole structure of any directories that a user may delete, and finally, telling it to not keep certain types of files.
