Class BackupRetentionInheritance (0.5.0) 

BackupRetentionInheritance(value)

How a backup's enforced retention end time is inherited.

    This is the default behavior.
MATCH_BACKUP_EXPIRE_TIME (2):
    The enforced retention end time of a backup
    will always match the expire time of the backup.

    If this is set, the backup's enforced retention
    end time will be set to match the expire time
    during creation of the backup. When updating,
    the ERET and expire time must be updated
    together and have the same value. Invalid update
    requests will be rejected by the server.
