> When trying to create a template from a snapshot with S3 secondary storage, the command immediately fails with a NullPointerException.
> This appears to only happen when there is a pre-existing snapshot folder in the NFS staging store. This indicates that there is something wrong with the copy command (e.g., it's using 'mkdir' instead of 'mkdir -p').
> The issue can be worked around by deleting the existing snapshot folder on the staging store every time you want to create a new template. This is obviously not viable for end users.
> This issue should be fixed before 4.4 ships because it should be a stupid simple thing to correct, but completely breaks restoring snapshots for end users. Waiting for 4.5 would be far too long for an issue like this.

> I'm guessing it's an issue with the mkdirs() function in the code, but I've been unable to find it.
