SqlServer备份和恢复

备份

---创建测试数据库chen20181123

create database chen20181123

(name=chen_data,

filename='D:\hrtest\DB\testdata\chen20181123_data.mdf',

size=10MB,

filegrowth=1MB)

log on

(name=chen_log,

filename='D:\hrtest\DB\testdata\chen20181123_log.ldf',

size=1MB,

filegrowth=10MB);

---创建测试数据

use chen20181123

create table t1(id int,a varchar(100));

insert into t1 values(1,'a');

insert into t1 values(2,'b');

insert into t1 values(3,'c');

---数据库全备

BACKUP DATABASE chen20181123

TO DISK='D:\hrtest\DB\testdata\backup\chen20181123_full.bak' WITH COMPRESSION

insert into t1 values(4,'d');

insert into t1 values(5,'e');

---数据库差异备份

BACKUP DATABASE chen20181123

TO DISK='D:\hrtest\DB\testdata\backup\chen20181123_1.bak' WITH COMPRESSION,DIFFERENTIAL;

insert into t1 values(7,'f');

insert into t1 values(8,'g');

---数据库日志备份

BACKUP LOG chen20181123 TO DISK='D:\hrtest\DB\testdata\backup\chen20181123_2.trn' WITH COMPRESSION;

insert into t1 values(9,'f');

insert into t1 values(10,'g');

---19:51

delete t1;

恢复场景

---恢复全备+差异备份恢复

restore filelistonly from disk='D:\hrtest\DB\testdata\backup\chen20181123_full.bak';

RESTORE DATABASE chen20181123_1

FROM DISK = 'D:\hrtest\DB\testdata\backup\chen20181123_full.bak'

WITH NORECOVERY,

---20:33

BACKUP LOG chen20181123 TO DISK='D:\hrtest\DB\testdata\backup\chen20181123_3.trn' WITH COMPRESSION;

---恢复全备+差异备份+日志备份+新日志备份恢复

USE MASTER

RESTORE DATABASE chen20181123_3

FROM DISK = 'D:\hrtest\DB\testdata\backup\chen20181123_full.bak'

WITH RECOVERY;

select * from chen20181123_3.dbo.t1; ---0

---恢复全备+差异备份+日志备份+新日志备份+基于时间点不完全恢复

USE MASTER

---drop database chen20181123_5;
