SQL2005自动镜像备份

公司为提高数据的安全性，采用多媒介存储的方式备份，

自己写了一份公司备份策略，

/*自动备份过程 add at 2009-3-24*/

Declare @Load1 varchar(max),@Load2 varchar(max),@load3 varchar(max),@FileName varchar(200)
Declare @DBName varchar(100)
/*备份路径设置*/
select @Load1='C:/backup/',@Load2='S:/backup/',@load3='T:/Backup/'
/*备份文件名称生成*/

select @FileName='_backup_'+cast(year(getdate()) as varchar(10))+right('00'+cast(month(getdate()) as varchar(10)),2)
+right('00'+cast(day(getdate()) as varchar(10)),2)+right('00'+cast(datepart(hh,getdate())as varchar(10)),2)
+right('00'+cast(datepart(MI,getdate())as varchar(10)),2)+'.bak'

Declare DBList cursor for
select name from master.dbo.sysdatabases where name not in ('master','model','msdb','tempdb','fabricstock')
open DBList
fetch next from DBList into @DBName
while @@fetch_status=0
begin
exec('
begin try
backup database '+@DBName+' to DISK='''+@load1+@DBName+@filename+ '''
mirror to DISK='''+@load2+@DBName+@filename+'''
mirror to DISK='''+@load3+@DBName+@filename+''' WITH FORMAT
end try
begin catch
print '''+@DBName+''''+'''备份失败''
end catch ')

fetch next from DBList into @DBName
end
close DBList
deallocate DBList
