寫個存儲過程備份不就好了麼，然後規定時間讓job運行，還原的也可以這樣做

备份我用存储过程：
ALTER PROCEDURE dbo.[backup]
@BackupPath nvarchar(255),
@DataBaseName nvarchar(255)
AS
BACKUP DATABASE @DataBaseName TO DISK = @BackupPath
RETURN
恢复：
string strSql="Alter Database ["+System_Biz.DataBaseName+"] Set Offline with Rollback immediate; ";
strSql=strSql+"RESTORE DATABASE ["+System_Biz.DataBaseName+"] FROM DISK = '"+System_Biz.RegainPath+"';";
strSql=strSql+"Alter Database ["+System_Biz.DataBaseName+"] Set OnLine With rollback Immediate";
string strconnection="server=localhost;User ID=sa;password="+System_Biz.DataBasePassword+";database=master;";
注意恢复时必须用sa账号
