Kriti;

Unfortunately JClouds only supports block blobs larger than 64MB; not page
blobs [1]. This is mostly because support for large blob types was
initially written for managing large files like zip files; not the
random-seek VHD files which have to be aligned to 512 byte boundaries[2].

The work required to get page blobs in place is not technically hard; but
there may be a bit of work in making sure the JClouds API for azure blob
remains clean.

Personally I'd be pretty interested in this support; but my work does not
have an immediate need for it. If you want to take a stab at it I would be
more than willing to help out.

Also; if you just need to copy vhds between storage accounts you can use
the async copy API[3]. The only reason I mention this is that my company
has many VHDs which largely stay within Azure; but we had the need to move
them from storage account to storage account. You can do this with shared
access keys[4].
