内容简介

本文档基于SQLServer官方文档的备份恢复内容，结合生产环境实际情况，详细讲解SQLServer备份的类型、配置、恢复流程等内容。风哥教程参考SQLServer官方文档Backup and Restore、Recovery Models等相关章节。

Part01-基础概念与理论知识

1.1 SQLServer备份类型

SQLServer的备份类型：

完整备份：备份整个数据库
差异备份：备份自上次完整备份以来的更改
事务日志备份：备份事务日志记录
文件备份：备份单个文件或文件组
部分备份：备份主文件组和只读文件组

1.2 SQLServer恢复模式

SQLServer的恢复模式：

简单恢复模式：不支持事务日志备份，自动截断事务日志
完整恢复模式：支持完整的时间点恢复，需要定期备份事务日志
大容量日志恢复模式：为大容量操作优化，减少日志空间使用

1.3 SQLServer备份策略

备份策略的组成：

备份频率：根据数据重要性和变化率确定
备份类型：完整、差异、事务日志的组合
备份存储：本地磁盘、网络存储、云存储
备份验证：确保备份的有效性
备份保留：根据业务需求确定保留期限

Part02-生产环境规划与建议

2.1 SQLServer备份规划原则

备份规划原则：

根据RTO（恢复时间目标）和RPO（恢复点目标）制定备份策略
考虑数据量和备份窗口时间
使用多种备份类型组合，平衡备份时间和恢复时间
定期测试恢复流程，确保备份的有效性
考虑异地备份，应对灾难恢复

风哥提示：生产环境应使用完整恢复模式，确保数据安全

2.2 SQLServer备份存储策略

备份存储策略：

存储类型            优点                  缺点                  适用场景

本地磁盘            速度快，成本低          单点故障风险高          临时备份，快速恢复

网络存储            集中管理，容量大        网络依赖，速度较慢       常规备份存储

云存储              高可用性，弹性扩展       成本较高，网络依赖       异地备份，灾难恢复

磁带存储            成本低，长期存储        速度慢，管理复杂         归档备份，长期保存

2.3 SQLServer备份验证方法

备份验证方法：

RESTORE VERIFYONLY：验证备份文件的完整性
定期恢复测试：在测试环境中恢复备份
检查备份历史：确保备份作业正常执行
监控备份大小：确保备份大小合理
使用校验和：在备份时启用校验和

3.1 SQLServer备份配置

备份配置：

— 创建备份目录
EXEC xp_cmdshell ‘mkdir /sqlserver/backup’;
GO

— 设置恢复模式
ALTER DATABASE fgedudb SET RECOVERY FULL;
GO

— 执行完整备份
BACKUP DATABASE fgedudb
TO DISK = ‘/sqlserver/backup/fgedudb_full.bak’
WITH COMPRESSION, CHECKSUM, STATS = 10;
GO

— 执行差异备份
BACKUP DATABASE fgedudb
TO DISK = ‘/sqlserver/backup/fgedudb_diff.bak’
WITH DIFFERENTIAL, COMPRESSION, CHECKSUM, STATS = 10;
GO

— 执行事务日志备份
BACKUP LOG fgedudb
TO DISK = ‘/sqlserver/backup/fgedudb_log.trn’
WITH COMPRESSION, CHECKSUM, STATS = 10;
GO

— 备份到多个设备（镜像备份）
BACKUP DATABASE fgedudb
TO DISK = ‘/sqlserver/backup/fgedudb_full1.bak’,
DISK = ‘/sqlserver/backup/fgedudb_full2.bak’
WITH MIRROR TO
DISK = ‘/sqlserver/backup_mirror/fgedudb_full1.bak’,
DISK = ‘/sqlserver/backup_mirror/fgedudb_full2.bak’
WITH COMPRESSION, CHECKSUM;
GO

— 验证备份
RESTORE VERIFYONLY
FROM DISK = ‘/sqlserver/backup/fgedudb_full.bak’;
GO

— 查看备份信息
RESTORE HEADERONLY
FROM DISK = ‘/sqlserver/backup/fgedudb_full.bak’;
GO

— 查看备份历史
SELECT
backup_set_id,
database_name,
backup_start_date,
backup_finish_date,
backup_size / 1024.0 / 1024.0 AS backup_size_mb,
type,
is_compressed
FROM msdb.dbo.backupset
WHERE database_name = ‘fgedudb’
ORDER BY backup_start_date DESC;
GO

执行结果：
