(GcpNfsVolume) Restore in new Filestore

[abalaie]

Description

In GCP, you can restore a Filestore backup in 3 ways:

• In place restore: replaces the existing Fileshare of the source Filestore with backup content
• Out of place restore: replaces the existing Fileshare of an existing Filestore different from the source Filestore with backup content
• Restore in new Filestore: Creates a new Filestore and as part of the creation, restores an existing backup content to the Fileshare of newly create Filestore.

The request is to implement "Restore in new Filestore" for GCP.

Reasons

GCP doesn't support the restore of a backup of ZONAL, REGIONAL and ENTERPRISE tiers into an existing Filestore, regardless of if it is the source Filestore or another Filestore. For the listed tiers, the only way to do the restore, is to do it as part of new Filestore creation.
Therefore we need to have this feature available otherwise the listed tiers are not practically usable.
