Review comment:
Yes, some secondary storage (in our case Swift) cannot take partial
snapshots, so we noticed the issue.

> Key: CLOUDSTACK-10222
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10222
> 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
> Environment: XenServer, Swift
> Reporter: Khosrow Moossavi
> Labels: easyfix
> Fix For: 4.11.0.0
>
>
> 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.
