Description

azurerm_backup_policy_file_share does not support the new vaulted backup tier, and defaults to using snapshot

The policy can be manually changed to Vault-Standard as a workaround. Note that switching to vaulted tier appears to apply the daily/weekly/monthly/yearly retention settings to the vault, and a new retain snapshots for x day(s) setting is exposed.

Snapshot tier

Vaulted tier

Please could you add support for this, thanks!
