Ext4 All data deleted, can't recover

I don’t know what I did, but I made a disaster and lost around 50000 family pictures. There was inside a raid1.

ls return just 2 files:

root@NAS:/srv/dev-disk-by-label-RAID1# ls
aquota.group  aquota.user

I can use photorec but I will lose names and folders.

I tried testdisk, and can see all deleted files but can’t recover them, testdisk return 0 copied, 0 failed

I want to use another superblock because I think there is a problem with the filesystem.
