SQL Server 备份和还原数据库

备份：

--完整备份
declare @db_name varchar(100)
set @db_name = 'WSS_Content_Test';
declare @db_location varchar(100)
set @db_location = 'D:spbr0002000000B.bak'; --保证有此文件夹
 
backup database WSS_Content_Test
to disk = @db_location
with name = @db_name,stats=5,noinit,noskip,noformat,norewind;

--差异备份
--with name = @db_name,stats=5,noinit,noskip,noformat,norewind,differential;

还原：

declare @db_name varchar(100)
set @db_name = 'WSS_Content_Test';
declare @db_location varchar(100)
set @db_location = 'D:spbr0002000000B.bak'; --保证有此文件夹
 
if exists(select * from master..sysdatabases where has_dbAccess(name)=1 and name=@db_name)
begin
    alter database WSS_Content_Test
    set single_user with rollback immediate
end
restore database WSS_Content_Test
from disk = @db_location
with stats=5,file=1,replace,norewind,nounload,recovery;
