>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the 
> default.) 
>          Components: Secondary Storage, Snapshot, XenServer
>    Affects Versions: 4.10.0.0, 4.11.0.0
>         Environment: XenServer, Swift
>            Reporter: Khosrow Moossavi
>            Priority: Major
>              Labels: easyfix
>             Fix For: 4.11.1.1
>
>
> When user creates a snapshot (manual or recurring), snapshot remains on the 
> primary storage, even if the snapshot is transferred successfully to 
> secondary storage. This is causing issues because XenServer can only hold a 
> limited number of snapshots in its VDI chain, preventing the user from 
> creating new snapshots after some time, when too many old snapshots are 
> present on the primary storage. 
> {code:java}
> reason: SR_BACKEND_FAILURE_109 The snapshot chain is too long
> {code}
> Proposed solution:
> Keep only one snapshot (last successful) on the primary storage regardless 
> that it was a full or partial snapshot.
