At least the BDB backend has recovery. FSFS doesn't.

I have used BDB with very large repositories (~50Gb) and it survived many
hardware failures (after running recovery and with proper log files
archived). Now I'm also using FSFS, and had to spend about a week
manually recovering from corruptions (caused by hardware failure).

So, BDB has more buttons to push and dials to adjust, but at least it
had the recovery option which worked very well. But now I wouldn't
recommend it anymore because subversion upstream focus more on FSFS.
