Support Backup of Snapshots for Managed Storage
This PR adds an ability to Pass a new parameter, locationType,
to the âcreateSnapshotâ API command. Depending on the locationType,
we decide where the snapshot should go in case of managed storage.
There are two possible values for the locationType param
1) `Primary`: The standard operation for managed storage is to
keep the snapshot on the device (primary). For non-managed storage,
this will
give an error as this option is only supported for managed storage
2) `Secondary`: Applicable only to managed storage. This will
keep the snapshot on the secondary storage. For non-managed
storage, this will result in an error.
The reason for implementing this feature is to avoid a single
point of failure for primary storage. Right now in case of managed
storage, if the primary storage goes down, there is no easy way
to recover data as all snapshots are also stored on the primary.
This features allows us to mitigate that risk.
