Before an incident, configure FSx for Windows File Server to back up important shared files daily and retain backups for seven days.
Loss of changes since the latest available backup is acceptable. Prepare to restore a new file system from that backup and switch access.
Which configuration is most appropriate?
Configure seven-day automatic daily backup retention and verify capture and restoration to a new FSx for Windows File Server file system.

Foundation review
Enable daily capture and inspect results
Automatic daily backup retention is 0–90 days; zero disables it. Seven-day retention supports saved backup times, not any instant before an error. Choose a window with workload and maintenance in mind, and verify completed backups.
Restore a new file system
Restore an available backup to a new file system with the same deployment type and storage capacity. Prepare the same Active Directory domain, or a domain trusted by the original, for user access. Validate data and access before cutover; Multi-AZ alone does not undo historical incorrect updates.
