[pbs-devel] [PATCH proxmox-backup v3 6/7] api: config: avoid unneeded backend instance on s3 store recreation

[Christian Ebner]

The backend type is already known from the config and can be used to
check if the s3-refresh should be performed, there is no need to
actually instantiate the backend at this point.
