Deleted files available on UPNP client, Not on TS-220. How do I restore. (2024)

As the tile I have accidently deleted many media files which obviously are not visible on the TS-220 such as Parent directory tree or Recycle bin but I can access and play them on a UPNP player.

How do I restore all these available files and folders.

Hi and welcome to the forum.

This sounds a little strange. If the files have been deleted from the NAS, then your player could only play them if it had cached the files somewhere else.

What sort of media files are playable? Images, audio, videos?

How did you delete the media files? Via a shared folder mounted on a client device? Via the File Station application in QTS? Some other way?

Do you have backups of the deleted files?

Do you mean DLNA (Digital Living Network Alliance) rather than UPnP (Universal Plug and Play) ?

If you deleted the actual files, and they are not in a library structure somewhere else, and you do not have the recycle bin enabled, and you do not have a backup, then there is not much hope for recovery.

Maybe you are accessing the transcoded copies?

QNAP TS-563-16G 5x10TB Seagate Ironwolf HDD Raid-5 NIC: 2x1GB 1x10GbE
QNAP TS-231P-US 2x18TB Seagate Exos HDD Raid-1

Ok, I tend to get carried away so I'm going to try and make it succinct.

Note: I have recoverd the files via Windows read below.

First to answer some of the questions above:

Cache: no cache, players as dumb as dumb can be.
Files: Video files
How delete: no one knows not even me.
Backup: This is the backup.
DLNA: No, plain old UPNP
Library structure/Recycle Bin/Backup: Not present but the thing is I actually recovered by finding them with Qfinder > See image
Transcoded Copies: No idea what that is so I say no.

Ok, I added an image that hopefully is understandable. In the image the folders and path for 'Movies and TV Shows' is not anywhere to be found by File Station 5 or Filezilla for example. Also there seems to be no share for them either but if I Click on QFinder 'Network drives' I can find them as I can also see them In UPNP and yes the files are playable.

If I create a 'Map a Network Drive' in Windows for all the shares. The missing folders and files are not there.

FS5 and FZ show disk usage of 190GBs total the actual is unknown but in excess of 600GB/s total with the 'Movies and TV Shows' files.

Whilst this is now and interesting quirk since I recovered the files questions remain:

Why can UPNP and Qfinder 'Network Drives' see the missing Files and folder and not TS-220 firmware or Filezilla in FTP.
What kind of security issue would this represent for technically this bypasses any security including shares, I think?
What kind of recovery can be done to restore the file and folder structure without starting from scratch.

Great then restore the files from your normal storage location, otherwise the NAS is NOT a backup!

Make sure you login to the NAS with admin (not an alternative user in the admin group)

Great then restore the files from your normal storage location, otherwise the NAS is NOT a backup!

So let me see if I understand you. If I back up a NAS to another NAS it's not a backup because it's a NAS. If I back up my Devices to a NAS it's not a backup because It's a NAS. WOW, my mind is blown, to think 'network attached STORAGE' cannot be a backup because it doesn't say backup. So then it can't be used for anything other than storage, what is storage?, no media streaming, no CCTV, Nothing just storage, storage of what exactly? Hang on! that means I can't backup to a HDD and SSD a USB device either, because, well, they're STORAGE devies.

Do you think if I grab a piece of paper and print or write out all the ones and zeros out I can use that as a backup, O' wait paper can get wet, be lost, eaten by silverfish, Damn I'm so glad you pointed out to me. So what do you use as a backup that is infallible.

I think you're confusing RAID with the term backup. The term "RAID is not a backup" , not only that but you do realise that backups can actually fail and only discoverd when the primary has failed and you do a restore. I think some of the terms are file corruptions, bit rot, read write errors failing disks amongst hundreds of possible causes, causes that smart may not pickup or the file systems protections do not pick up either.

A NAS is not/can not be a backup. WOW

I am not confusing anything.

If your NAS is your storage location (meaning you delete your original files when you copy/move them, your NAS is not a backup)

So if you say your files are gone and there is nowhere to restore the files from.. why would you say that was your backup ?

Initial copy of data - Original
Second copy of data - Backup

You seem very confrontational. Maybe relax a little with the people trying to understand your issues and help you.

As an aside, I had never heard of anyone using UPnP for media playback before. It looked like it was a simple samba setup in the screen shots. That was why I had asked about DLNA.

Is the folder with your files a hidden folder?

Us WinSCP with the "admin" account and search for a known file to find where the hidden folder is located.

Whhhat???

If I have a snapshot and I restore from a snapshot does not mean that the snapshot is a backup?
I have a spare key to my house. Does that mean that If I lose my key my spare key is not the backup?
I have a spare wheel on my car. If I get a flat and use it does that mean that my spare wheel is not a backup?

In all those cases the snapshot could be corrupt, the spare key could have been lost and the spare wheel could be flat. They are still the backups. A NAS is not for or a backup???????????? I still can't wrap my hear around that.

Initial copy of data - Original > Yes the one in everyday use on any device.
Second copy of data - Backup > exactly that which is stored on a NAS or any storage device.

I'm not being confrontational, it just blows me away at the ridiculousness of his response for someone whom is also supposed to be a Guru with over 35210 posts. He/she was trying to be clever providing absolutely no help/insight or constructive information on the issue.

The fault is mine for I put 'Restore' only because I didn't want the response to be forget it and ignore that you can see them in UPNP just start again. By placing the word 'Restore' I was hoping to find what happened, learn how to restore the structure, why can I see them in UPNP and Windows and above all is there a security risk that deleted files are still available. But no, I still got trolled "Great then restore the files from your normal storage location, otherwise the NAS is NOT a backup! ". My fault.

DLNA is derived from UPNP. UPNP is an old less secure idiot proof standard for connecting devices (from simpler times)

If they where they shouldn't be avaialbe in the network.
Did it with Filezilla and aslo downloaded WinSCP searched for know missing files and no luck. Also did a full / *.* search and copied the list of thousands to Notepad++ and did a search. No known missing files.

Have a look at the screen shot: The missing files show up under This PC with NASE2DFDB but not under Network with Ip 192.*****

Some of what you see on the windows side is bogus as they look like remnants of previously mapped locations, which doesn't mean they still exist.

It *looks* to me that you previously had a share with the label "videos" which no longer exists.

@dolbyman's point was that if the NAS was the backup, then there would be a location where the original existed, and could be used. Move on. Let it go. Arguing about silly things is being confrontational and serves no purpose, and doesn't encourage anyone to offer useful advice.

I would forget about all the silly tools and their lack of proper searching. Drop into an SSH session where you really know where you are in the structure. Go to the root (/) and use the "find" command to search for a known file (or manually walk through the structure), or the "videos" folder. Perform the same search (with "find") after navigating into the @recycle directory as well. The various Gui tools don't necessary search that location or other system directories.

I'm confused about where you say you have recovered the files via windows. If you can access them, then copy them to another location to safeguard them as you play around in the system. It seems to me like the solution here is to recreate the share pointing to their actual location, which seems to be eluding you as to where it actually is.

If you examine the storage space, and what is used, does it seem to reflect these files "exist" somewhere on the drive?

Another rider of the automated forum ranks..ughh...must be full moon.

My first post already contained a hint about a user account problem....so much for no useful info.

If you want to continue to make a fool of yourself by demonstrating that you have no idea what you are talking about..(Snapshots on a 15 year old CAT1 device..and even if it had snapshots..you are scrambling for your files...are you arguing for home owners insurance after your house burned down and you did not sign or pay for that policy?) fine you do you. Not my data not my problem.

I'll keep out if it..otherwise I might be tempted to lock this topic up.

No, they are real, exactly what I see and can also access in UPNP player and Windows playing or VLC. Not only that but as previously said qnap and Filezilla show 190GB when I can access the missing files of over 500GBs. The files exist.
I also tried to copy a video file into the deleted Movies folder through Windows and it would not do it but I can copy out. That would could be part of the missing share as well, as in read only.

It *looks* to me that you previously had a share with the label "videos" which no longer exists.

This is part of the interest in all this. If that's the case why can I still access the files. UPNP player is UPNP (not samba) Windows is Samba and connected via SMB so where is the security. SMB > NO Share > No access and yet I can access.

I would forget about all the silly tools and their lack of proper searching. Drop into an SSH session where you really know where you are in the structure. Go to the root (/) and use the "find" command to search for a known file (or manually walk through the structure), or the "videos" folder. Perform the same search (with "find") after navigating into the @recycle directory as well. The various Gui tools don't necessary search that location or other system directories.

I may try that later on but I'm thinking of dropping it and possibly put forward a bug report instead for the following reasons:

1- Deleted files still available and fully functional under UPNP and windows PC.
2- Files not visable on TS-220 or FTP clients.
3- TS-220 and FTP clients report 190GB use when actual is over 600GB/s with the deleted accessable files and folders.
4- Deleted files accessable in Windows are under SMB when there is no Share

I'm confused about where you say you have recovered the files via windows. If you can access them, then copy them to another location to safeguard them as you play around in the system.

This is moot. The recovery is no issue. I'm playing with the system to see if I can find out the root cause as to the points above for reporting a bug.

It seems to me like the solution here is to recreate the share pointing to their actual location, which seems to be eluding you as to where it actually is.

No, I know where it's supoposed to be, you can see the tree in one of my image attached above. I want to know why those deleted files and directories are still available especially without a share and see and learn if I can recreate the tree such as repairing the files system.

If you examine the storage space, and what is used, does it seem to reflect these files "exist" somewhere on the drive?

No, that's what makes it interesting, as above TS-220 and FZ report 190GB used space when the total is in excess of 600GB. The Movies folder is over 200GBs alone.

Aaannnnd that's a strike ...
