The reason this is placed her (very inconveniently I know) is that the 
HttpClient is consumed by the BackupWriter instance, and I have to reuse
the same client (as otherwise I get locking issues).

Open for further discussion if there is a better way to handle this, I 
also would like to move this to the match arm for pxar backup creation 
if possible.
