Just reinstalled my distro and deleted my /

I’ve reinstalled my personal linux distro, and wiped my / during the process. Only leaving my home dir intact. I forgot about my installed mongodb DB, and so didn’t take any backups whatsoever.
I’ve done some research and it seems like mongo installs its db at /data. Is there any way possible to reclaim any of my data back. Cache/logs/etc. I know it’s over, but just if there’s anything I can do to mitigate the data loss.
Thanks
