Answer 1

I guess you backup your databases, and if, you can get the information from backup history:

-- Transact-SQL script to analyse the database size growth using backup history.
DECLARE @endDate datetime, @months smallint;
SET @endDate = GetDate();  -- Include in the statistic all backups from today
SET @months = 12;           -- back to the last 6 months.

;WITH HIST AS
   (SELECT BS.database_name AS DatabaseName
          ,YEAR(BS.backup_start_date) * 100
           + MONTH(BS.backup_start_date) AS YearMonth
          ,CONVERT(numeric(10, 1), MIN(BF.file_size / 1048576.0)) AS MinSizeMB
          ,CONVERT(numeric(10, 1), MAX(BF.file_size / 1048576.0)) AS MaxSizeMB
          ,CONVERT(numeric(10, 1), AVG(BF.file_size / 1048576.0)) AS AvgSizeMB
    FROM msdb.dbo.backupset as BS
         INNER JOIN
         msdb.dbo.backupfile AS BF
             ON BS.backup_set_id = BF.backup_set_id
    WHERE NOT BS.database_name IN
              ('master', 'msdb', 'model', 'tempdb')
          AND BF.file_type = 'D'
          AND BS.backup_start_date BETWEEN DATEADD(mm, - @months, @endDate) AND @endDate
    GROUP BY BS.database_name
            ,YEAR(BS.backup_start_date)
            ,MONTH(BS.backup_start_date))
SELECT MAIN.DatabaseName
      ,MAIN.YearMonth
      ,MAIN.MinSizeMB
      ,MAIN.MaxSizeMB
      ,MAIN.AvgSizeMB
      ,MAIN.AvgSizeMB 
       - (SELECT TOP 1 SUB.AvgSizeMB
          FROM HIST AS SUB
          WHERE SUB.DatabaseName = MAIN.DatabaseName
                AND SUB.YearMonth < MAIN.YearMonth
          ORDER BY SUB.YearMonth DESC) AS GrowthMB
FROM HIST AS MAIN
ORDER BY MAIN.DatabaseName
        ,MAIN.YearMonth
