Bug 997659

Description of problem:

See https://www.openshift.com/forums/openshift/how-to-create-a-custom-targz-package-reduced-from-my-backup-snapshot#comment-33320  

Use case:  User wants to clean up his snapshot.tar.gz before he runs snapshot-restore to save time on the upload.  Other reason is because on slow internet connections, it's easier to trigger the 1hr timeout on builds which causes the snapshot-restore to fail - the 1hr timeout includes the upload time (another questionable bug for another report).

The procedure should be easy:  
1) tar -zxvf snapshot.tar.gz
2) delete all logs and images that user doesn't care about
3) tar -zcvf snapshotUpdated.tar.gz $UUID/  
4) rhc snapshot-restore $appName --filepath snapshotUpdated.tar.gz  

Expected:  The snapshot-restore should work.
Actual: The snapshot-restore fails with error (bottom of post)

Workaround is to us "tar -zcvf snapshotUpdated.tar.gz ./$UUID/".  



Error starts here:
rhc snapshot restore wordpress --filepath worpdress2.tar.gz
