'Recycle Bin' capability on Thecus?

[jac]

Hi everyone,

I was wondering if anyone had any experience of whether the Samba server running on the Thecus has the ability to make use of the Samba VFS Recycle module? Details of this module can be found at us1.samba.org/samba/docs/man/Samba-HOWTO-Collection/VFS.html#id380094

Essentially it seems that it remaps files 'deleted' on Samba accessed volumes to a directory structure that mimics the files original position but within a recycle directory. This effectively allows any files deleted to be recovered at a later date, a little bit like the Recycle Bin on a Windows system.

Anyone know anything about this module, is it enabled on the Thecus? I'd certainly appreciate anybodies opinions/comments on it.

Many thanks.

Anyone?

Failing that I was wondering if someone could have a quick look and tell me if there was anything under the /usr/lib/samba/vfs directory tree and if so what (i.e. any .so files)? (I don't currently have access to the N2100 I'm looking into this for, hence my request).

Thanks.

Looks like you're in luck. It appears to be there.

dbridges, many thanks for checking that out for me, it certainly looks like they've bundled all the standard VFS modules as part of the Samba distribution so this will be an interesting experiment and maybe a very useful feature for some if it works as documented. Looks like I'll be trying it out very soon, I'll post my findings.

Thanks.

Hi jac,

as the N5200 is having an equivalent SAMBA installation with recycle.so and friends I'm definitely interested in your investigations...

I'm waiting curiously for your results.....

I tried this out and it actually saves the deleted files. I think I will try to write a module for this if I have time.

[sharmy]

Any news on development of a recycle bin module? I am also very interested in this.

Thanks,

Sharmy

[wengi]

This would be a very important module for me.
Any news?

Can't help you with a full blown module, but to summarize and confirm what has been told in this thread already:

* undestand that if you manage to brick your nas with this, it's your own fault
* install the SSH module
* backup your smb.conf (located in /raid/sys/ in my n2100 firmware)
* find the [section] of the share you would like to equip with recycle functionality
* add these lines (or more if you've read the url in the opening post and understand the other possible options) with vi

vfs objects = recycle
recycle:keeptree = yes

* reload your samba (killall -HUP smbd)
* done.

The changes seem permanent but I'm guessing they'll disappear as soon as you modify your share(s) with the webgui again. To prevent that the person writing the full module for it would need to patch the recycle options into file /opt/apache/inc/smbconf.class.php function setShareDefaultParameters() every time the machine boots or something to that effect.

Have fun.

[dbridges]

The changes shouldn't disappear unless perhaps you're editing the share that the changes are on.

Even then it should only change the parts that it knows about.

Hi,

i am now using the racycle bin on all shares and it works great.
The only thing i am missing is a script to delete all content in the .recycle folder that is deleted for longer than x days.
I will try to write a script when i have the time for this.

thanks for the help

wengi

[ferg]

how do i verify that this is working?
I have previously allows the/raid directory to be shared, and so logically i would like to setup a recycle bin for everything contained. I have added the lines to the smb.conf and restart the smb server as well as the box but i have not seen a .recycle folder anywhere to indicate that it has been successful.

Any thoughts?

[omega]

I just tried setting a recycle bin on my N5200 and it works great.

The .recycle folder will be created in the top directory of the share when you delete a files the first time. Make sure that your windows explorer shows hidden files.

Hi all,

to bring a little update: Use the following script to delete files in the .recycle folders that are older than x days:
#!/bin/sh
#
# wengi 03/2008
#

# Delete files older than ... days
days=14

for ordner in `find /raid/ -type d  -name .recycle`
do
      #delete files older than ...
      find $ordner -type f -mtime +$days -print0 | xargs -0  rm -f
      #delete empty folders
      find $ordner -depth -type d -empty -exec rmdir {} \;
done
Add is to crontab to run every night. Done.

BUT: This will act on ALL folders named ".recycle" on you HDD. It is not a good idea to create a so called folder to store important files

You have a recycle bin which will be cleaned x days after file deletion.

Hi wengi,

nice little script, thanks a lot.....

I'd like to suggest two little improvements though:
1) if a share (the parent of the .recycle folder) contains spaces, your script fails
2) why searching the complete file tree below a share for the .recycle folder? The .recycle folder is always a direct child of the share folder. This will speed up your script enormously as it doesn't search the whole file tree below /raid/data.
3) Not an error but an enhancement: the new script basically works for N2100 and N5200 - you only need to comment/uncomment the topDir variable definition in the new script accordingly.

Below you'll find my small improvements to your script which fixes the issues described above:

#!/bin/sh
##
##  omega: 4.4.2008
##

# Use this definition for topDir for N2100
topDir=/raid

# Use this definition for topDir for N5200
#topDir=/raid/data

recDir=.recycle

# Delete files older than ... days in recycle bin
maxDays=14

[ -d "$topDir" ] || exit 1

for recycleBin in "$(find "$topDir" -maxdepth 2 -type d -name "$recDir" -print)" ; do
   # Delete files older than ... in all dirs in recycle bin
   find "$recycleBin" -type f -mtime +$maxDays -print0 | xargs -0 rm -f

   # Delete all empty folders (might became empty after deleting files)
   find "$recycleBin" -depth -type d -empty -exec rmdir {} \;
done

exit 0


Hope you and some others might find it useful.....
