Thanks for the feedback Andrei,

In my case the problem seems unrelated to S3 as when I configure NFS as
my secondary storage I get the same problem. My problem seems to be that
the system tries to write the snapshot to directory path
like /mnt/e5c41.../snapshots/2/3/ but as for some reason it finds
that /mnt/e5c41.../snapshots/2/3/ doesn't exist as the /mnt/e5c41... is
not actually mounting secondary storage at that time. If I mount it
manually, the path is there but the system is not doing it automatically
for me.

Tom.
