I was trying to copy my EXT4 partition as backup and I accidentally putted my NTFS partition containing my data on the dd command.

Now my data is lost :(

I've tried testdisk but it wasn't able to find partition. What should I do?

Update: This was the command I ran:

dd if=/dev/sda2 of=/dev/sda1 bs=64K conv=noerror,sync

What is overwritten is gone. dd copies data from source (if=) to destination (of=) and overwrites data on destination. Testdisk can only recover data that hasn't been overwritten. A current backup is your only hope now.

Is there any way to recover what can be recovered by repairing the filesystem?

No! ddcopies block for block and overwrites the destination - what is overwritten is gone.
