maxRetentionDays

The AWS Backup Vault Lock configuration that specifies the maximum retention period that the vault retains its recovery points. This setting can be useful if, for example, your organization's policies require you to destroy certain data after retaining it for four years (1460 days). If this parameter is not included, Vault Lock does not enforce a maximum retention period on the recovery points in the vault. If this parameter is included without a value, Vault Lock will not enforce a maximum retention period. If this parameter is specified, any backup or copy job to the vault must have a lifecycle policy with a retention period equal to or shorter than the maximum retention period. If the job's retention period is longer than that maximum retention period, then the vault fails the backup or copy job, and you should either modify your lifecycle settings or use a different vault. Recovery points already saved in the vault prior to Vault Lock are not affected.
