Bug Description

env: rbd as cinder backend, swift as cinder bakcup store.

cinder backup-create makes connection to ceph cluster, and read data from ceph cluster.
Then put data to swift.

The problem is that cinder doesn't close connection to ceph cluster even after the backup is finished.

The connection count increases until exceed max open files, at last, it results in OSError: [Errno 24] Too many open files
