ReadyNAS 2304 data Recovery on machine?
Hi, one of my customes uses a RN 2304 with 2x 4 TB in X-RAID. Everything works fine (no errors or downtime so far) but today i was asked to retrieve an defective *.xlsx file from that nas. The...
The underlying operating system is Debian Jessie. Yes, you can SSH into the unit. It has to be enabled on the Settings screen of the GUI, then you log in as user root using the NAS admin password. Note that since you are root, you can do things you shouldn't. The warning you get when you enable SSH is based on that -- Netgear will not help you out of a mess you created yourself via SSH. They will not automatically deny support because it is enabled.
With the BTRFS file system that the NAS uses, a lot of undelete tools won't work, and I think what you need to do is recover a delected old version. Here is one that claims it does, though I have no experience with it: btrfs-undelete on GitHub. If Copy on Write is enbled, that may help things out.
Have you tried workbook repair (Repairing-a-corrupted-workbook )? It's probably best to work on a local copy, not the original. There are some other recovery tools for Excel around, too.

Well snapshots are not enabled ....
I tried many ways to recover the excel file but none so far worked.
As of now i just get a blank view of excel 2019. Nothing is visible (no Worksheets etc.)
There were errors before but i can not reproduce them. And the customer aparently deleted the dead excel file from the nas and from the server already..... The copy i have just opens to a blank excel page ....
I might look into one of our backups to restore the defective excel file once more (He copied the excel file to the server wich has a continously running backup and now it seems as if he deleted thie copied file already)
I'll ask him if i should pursue this for any longer before i start breaking into the NAS

SSH can be disabled.
Use of ssh doesn't affect the [hardware] warranty at all. If can result in denial of software support, but only if Netgear believes that your use of ssh caused the problem.
