还原数据库“替换”总是出错

Question

我想在另一个 linux 服务器上拥有生产 sql server 数据库（在 Windows 上运行）来开发应用程序。

我从 Windows SQL Server 上的 sqlcmd shell 进行了备份，现在我尝试在 Linux 上的新安装 mssql 服务器中恢复此备份。

我用CREATE database BDRecup创建了数据库

使用RESTORE FILELISTONLY FROM DISK = N'/var/opt/mssql/backup/BDRecup_backup_2018_05_17_020000_9119969.bak'，我得到mdf 和ldf 名称。这个命令的输出很大，而且 shell 格式不好：

我尝试恢复

RESTORE DATABASE BDRecup FROM DISK = '/var/opt/mssql/backup/BDRecup_backup_2018_05_17_020000_9119969.bak'
WITH REPLACE,
MOVE 'BDRecupR' TO '/var/opt/mssql/data/BDRecup.mdf',
MOVE 'BDRecupR_log' TO '/var/opt/mssql/data/BDRecup_log.ldf'
GO

但我总是得到错误

Msg 3154, Level 16, State 4, Server Desktop, Line 1
The backup set contains a copy of a database different from the existing one 'BDRecup'.
Msg 3013, Level 16, State 1, Server Desktop, Line 1

如果我删除 BDRecup DROP database BDRecup 我会得到 The database 'BDRecup' does not exists.

发生了什么？ 谢谢

你能跑吗

SELECT @@Version 

在两台服务器上检查您是否没有从较高版本的 sql server 恢复到较低版本的 sql server ？

另外，你能分享一下结果吗

RESTORE FILELISTONLY FROM DISK = N'/var/opt/mssql/data/BDRecup_backup_2018_05_17_020000_9119969.bak'

根据提供的信息，您的恢复语句应该是：

RESTORE DATABASE BDRecup FROM DISK = '/var/opt/mssql/backup/BDRecups_backup_2018_05_17_020000_9119969.bak'
WITH REPLACE,
MOVE 'BDRecuperacionesR' TO '/var/opt/mssql/data/BDRecup.mdf',
MOVE 'BDRecuperacionesR_log' TO '/var/opt/mssql/data/BDRecup_log.ldf'

我还注意到您的 RESTORE FILELISTONLY 的备份文件名为

/var/opt/mssql/data/BDRecup_backup_2018_05_17_020000_9119969.bak

在还原数据库语句中，您正在从

进行还原

/var/opt/mssql/backup/BDRecups_backup_2018_05_17_020000_9119969.bak

目录和文件名的更改是故意的吗？您应该在一个备份文件上运行这两个语句

根据提供的信息和关于聊天的更多信息：正在使用的备份文件是差异备份，除了恢复差异备份之前的数据库完整备份之外，无法通过其他任何方式恢复。

The information that the backup is a full backup or differential can be 
identified from the filelistonly command by checking the DifferentialBaseLSN
column which is null for a full backup
