+++ This bug was initially created as a clone of Bug #1276839 +++

Description of problem:
Without '--sparse' option tar will not properly archive sparse file
and geo-replication will result in non-sparse file on the remote end.


Version-Release number of selected component (if applicable):


How reproducible:
Every time you have sparse files to geo-replicate the remote end will have
files full size and not sparse anymore.

Steps to Reproduce:
1. Copy a sparse file into a volume.
2. Wait for geo-replication to copy it to remote cluster.
3. Check the files on the remote end. It's no longer sparse.

Actual results:
Sparse files are no longer sparse after being geo-replicated.

Expected results:
Sparse files must remain sparse after being geo-replicated.
