Best free way to recover deleted files on NAS?
Hi, if someone could kindly point me in the right direction I will be very grateful.
I made a mistake yesterday and deleted 1500 music albums and 1000 movies. It's not the end of the world scenario, I can live without them. However, I'd like to take this opportunity to learn how to recover large amounts of data from RAID1 6TB WD Reds.
I found a Windows Application called R-Linux, I have taken drive 1 out of bay 1 and placed it into an external housing that is plugged into power and plugged into a usb 3.0 port on one of my iMacs running Windows 10. R-Linux is installed and currently scanning for movie and music files only.
R-Linux has been scanning for 2 hours with 7 hours to go. I see that R-Linux is finding specific file documents but I'm not exactly sure what it is finding, nor do I know if or how I can recover these files.
Has anyone here on the qnap forum dealt with the R-Linux application before?
Any pointers or suggestions are really welcomed.
Thank you very much.

Can’t you restore the files from backups?
Use the forum search feature before posting.
Use RAID and external backups. RAID will protect you from disk failure, keep your system running, and data accessible while the disk is replaced, and the RAID rebuilt. Backups will allow you to recover data that is lost or corrupted, or from system failure. One does not replace the other.

NAS: TVS-h674 | F/W: 5.0.1.2376 | 16GB | 3 x 18TB RAID 5

Unfortunately I only had the RAID1 I was just about to make a clone for a backup. Just bad luck, I guess.

Re: Best free way to recover deleted files on NAS?
did you use a static volume or thin/thick?
you can try photorec with a static volume ... on thick/thin you have to overcome lvm first

I used a static volume luckily. R-Linux is free and according to this video https://m.youtube.com/watch?v=xSYPWCd5-xk I'm using the application correctly. However, I'll look at photorec as well. Thanks for the suggestion.

And the recycle bin is empty or not switched on?

Re: Best free way to recover deleted files on NAS?
I gave up, photorec found many of the movie files but I would have to literally go through 1000 movie files and rename them as the application only find the deleted files with out names/metadata. So, it's not worth my time. Photorec isn't a bad app, however.

plain ext (static) vs. LVM layer (Pools)

Re: Best free way to recover deleted files on NAS?
I guess it would, data recovery would need low level access to the block storage device (single disk, md-raid) and on LVM the data is not on that level, it's higher up on the LVM

Re: Best free way to recover deleted files on NAS?
I guess my removed from QNAP Static disk when connected to Windows 10 linux disk readers (Diskinternals, R-Linux) was seen as Raid 0 LVM HDD with 5 (five) partitions rather than simple ext.
But if you are right, Static disk may seem more data secure in case of system/disk crash.
Does Thick volume have more overcap in terms of disk "pure" capacity (user data aera)?
I do have two WD Reds 4TB each, one is in Synology as single Basic volume and reports 3,933,123,952,640 bits, second is in QNAP as single Static volume and reports 3,686,260,187,136 bits only.
Both are disk no 1 respectively (which means system for QNAP, but I guess also system for Synology).
That's heck of 300GB difference!!

Regarding data recovery from QNAP disks there are on-line how-to's:

That's strange, I downloaded the linked file (Power Point presentation).
So I remove the link in doubt and leave attached presentation (zipped *.ppt). It's very detailed.
