If this policy is enabled, browser profile data can be backed up when backup is supported on the platform. If this policy is disabled, browser profile data cannot be backed up. If this policy is not configured, backup availability follows the platform default. This policy cannot be used to enable backup on platforms or in configurations where backup is not otherwise supported.

Disabled: AllowBackup = 0
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
