Problem

Deleted files in ibays or in users home directories on the server are lost forever.

Scenario

This has been a long known issue for network admins. Files stored on another computer/server. Accidentaly hit the DELETE key. Poof! Gone. Files aren't in the local Recycle bin on the local computer. This is especially frustrating for admins who map profile parts back to the server. The users desktop, documents, etc never find their way into the local recycle bin as the users expect.

Enable Recycle Bin for ibays

db accounts setprop ibayname RecycleBin enabled
db accounts setprop ibayname KeepVersions enabled 
signal-event ibay-modify ibayname

The first property enables the Recycle Bin feature. The second property KeepVersions ensures that when a file is deleted with the same name as one that was previously deleted the latest deleted file will be called “Copy #x of filename”.

Enable Recycle Bin for users

db configuration setprop smb RecycleBin enabled
db configuration setprop smb KeepVersions enabled

Expand the template...

/sbin/e-smith/expand-template /etc/samba/smb.conf

Remember to restart service...

/etc/rc7.d/S91smb restart


Warning.png Warning:
After making changes with the commands shown, you need to logoff your workstation and log back in again so those new access permissions are included in your login session. Recycle Bin will then function as expected.

The Recycle Bin folder will be created automatically the first time a file is deleted, so you will not see the folder until you delete something.

An admin can then go and retrieve the files on the server.

Recycle Bin Locations

For ibays the Recycle Bin is located at:

/home/e-smith/files/ibays/ibayname/files/Recycle Bin

For users the Recycle Bin is located at:

/home/e-smith/files/users/username/home/Recycle Bin

Automatic Cleaning Of Recycle Bin Content

The simple script below can be used to clean out the various Recycle Bins on a regular basis.

Note that this script is setup to use the last changed file attribute to selectively deletes files after they have been in the Recycle Bin for 30 days.

Setup the script to run either daily or weekly from cron.

Information.png Tip:
If after running the script you receive empty notification emails and you've checked the date flags of the files in the recycle bin and know that they should be removed, try changing the '-ctime' parameter to '-mtime'. bugzilla:7596

You can check the output by running this at the command prompt to see if any files are now being flagged for removal (you can adjust the number of days as you wish):

find /home/e-smith/files/users/*/home/Recycle\ Bin/* -type f -mtime +30 -print


#!/bin/bash

# ensure finds includes hidden files in the Recycle Bins
shopt -s dotglob

Changing the Recycle Bin name

You can change the name of the recycle bin by making a copy of the template fragment into the templates-custom tree and making your modifications there.

  1. Create the proper folder structure:
    mkdir -p /etc/e-smith/templates-custom/etc/smb.conf/ibays
    
  2. Copy the template fragment to the template-custom tree
    cp /etc/e-smith/templates/etc/smb.conf/ibays/10recyclebin /etc/e-smith/templates-custom/etc/smb.conf/ibays
    
  3. Use any editor to make your changes in the copied file
    nano /etc/e-smith/templates-custom/etc/smb.conf/ibays/10recyclebin
    

    Modifying this line:

    $vfs->{recycle}->{repository} = "Recycle Bin";
    

    to whatever you like for a name:

    $vfs->{recycle}->{repository} = "Add your name here";
    
    Information.png Tip:
    You can make the recycle bin hidden by adding a dot as a first character of the recycle bin name

  4. Now let the server take the necessary actions to have the changes reflected for all ibays (replace <ibayname> with the ibayname):
    signal-event ibay-modify <ibayname>
