Description (partial)

Symptom:
Backup workflow may appear to be stuck when available remote server disk space is not enough.

Conditions:
Accumulated disk space requirements from all managed services is larger than available remote disk space.

For example, 

Assume the following:
- MongoDB requires 5 GB
- GlusterFS requires 20 GB
- Available remote disk spaces is 21 GB

Since MongoDB sidecar backup process see 21GB available is enough for 5GB, it proceeds,
for GlusterFS sidecar backup process also see 21GB is enough for 20GB, it proceeds also.

But after MongoDB finish his part, Glusterfs encounter failure of "not enough disk space" because MongoDB already used up 5GB, i.e. available disk space is less than 20GB.
