First you say you tested as your frontend user, but the backend is
doing all writing, so is that the same user?. Second is the directory
per change accessed over nfs? Third how are rights to /mnt and
/mnt/rec1. Forth if using nfs is the volume mounted on the same place
on the backend giving the error?

And outside your question, I don't think it wise to apply such wide
permissions other then to /tmp.
