I know that a similar question has already been asked. This morning I accidentally formatted the wrong volume, containing mostly video files (about 30GB each).
I am currently trying to restore the files with Photorec, however it does not seem to work very well - all restored files are corrupted.
The volume is a Cryptsetup Luks ext4 volume (however not reformatted with LuksFormat, just mkfs.ext4)
Is it somehow possible to recover the old superblocks/journals? (And if yes, would that actually help restoring the old filesystem?)
