Ensure that your Amazon FSx for Windows File Server file systems have a minimum backup retention period set in order to fulfill your organization compliance requirements. The retention period represents the number of days to retain automatic backups. By default, FSx backups are retained for 7 days, however you can change this rate to any time period from 0 through 35 days. Prior to running this conformity rule by the Cloud Conformity engine you need to specify your own AWS FSx backup retention period in the rule settings.
Having a minimum retention period set for Windows File Server file systems will enforce your FSx backup strategy to follow best practices and meet regulatory compliance. AWS FSx backups are file-system-consistent, highly durable and incremental, allowing you to quickly restore to any point within the backup retention period configured. Retaining Amazon FSx file system backups for a longer period of time will allow you to handle more efficiently your data restoration process in the event of a failure.
Note 1: Setting the backup retention period to 0 days means that your file systems are never automatically backed up. Cloud Conformity strongly recommends that you use automatic backups for your FSx file systems, regardless of the level of critical functionality.
Note 2: As example, this conformity rule will use 14 days as the threshold for the sufficient backup retention period. However, you can adjust anytime the number of days (up to 35), to suit your organization requirements.
