    In ACS, all the snapshots are deleted from primary storage as soon as it is successfully
backed up and copied on secondary storage, hence this issue is not valid for ACS. 
    
    However a ticket should be raised to analysis and understand how incremental snapshots
work if not a single copy kept on primary.

>    Affects Versions: 4.8.0
>         Environment: Xen Server

>             Fix For: 4.8.1

> Issue Description
> ===============
> 1. Create an instance on the local storage on any host
> 2. Create a scheduled snapshot of the volume:
> 3. Wait until ACS created the snapshot. ACS is creating a snapshot on local storage and
is transferring this snapshot to secondary storage. But the latest snapshot on local storage
will stay there. This is as expected.
> 4. Migrate the instance to another XenServer host with ACS UI and Storage Live Migration
> 5. The Snapshot on the old host on local storage will not be cleaned up and is staying
on local storage. So local storage will fill up with unneeded snapshots.
