How to use the command line on SQLServer database backup and restore to another new database
First, we should have a regular backup plan, you can add a backup task in the database agents, the recommended practice is as follows:
Perform once a week: full backup
Executed once a day: Differential backup
Every hour: transaction log backup (transaction log can be achieved to restore the database to a specified second level)
Here we command to back up the database, these commands can also be applied to the backup job to go
DECLARE @FULLPATH NVARCHAR(100)
declare @DIFFPATH nvarchar(100)
declare @LOGPATH nvarchar(100)
SET @FULLPATH='数据库全备份路径.bak'
SET @DIFFPATH='数据库差异备份路径.bak'
SET @LOGPATH='数据库日志备份路径.bak'
BACKUP DATABASE 数据库名称 TO DISK = @DIFFPATH with DIFFERENTIAL #差异备份，仅备份数据
BACKUP DATABASE 数据库名称 TO DISK = @FULLPATH ＃完全备份，仅备份数据
BACKUP LOG 数据库名称 TO DISK=@LOGPATH #事务日志备份
Now we will need to log copied to other computers, we begin to restore the database to a new database
First, we may not know what the logical file name of the database that need to check your log file
#首先我们可能并不知道数据库的逻辑文件名是什么，需要查询一下日志文件
DECLARE @PATH NVARCHAR(100)
SET @PATH='数据库全备份路径.bak'
RESORE FILELISTONLY FROM DISK=@PATH
Secondly, after the inquiry into the logical file name can be used for the following recovery
#使用以上查询的逻辑文件名
RESTORE DATABASE 新数据库名称 FROM DISK = @PATH with RECOVERY,REPLACE,
MOVE 'DATA' TO 'C:\BAK\DATA\DATA.mdf',
MOVE 'DATA_LOG' TO 'C:\BAK\DATA\DATA.ldf'
Finally, if we need to continue to use the transaction log to recover data, then restore the above command,
WITH后面需要变成NORECOVERY
RESTORE DATABASE 新数据库名称 FROM DISK = @PATH with NORECOVERY
You can then right in the new database, select Restore, select a transaction log, choose our log file, you can select the target time required to recover.
