Question

I am actually trying to make a script (in Sql Server 2008) to restore one database from one backup file. I made the following code and I am getting an error -

Answer 1

Here's a way I am doing database restore from production to development:

NOTE: I am doing it via SSAS job to push production database to development daily:

Step1: Delete previous day backup in development:

declare @sql varchar(1024);

set @sql = 'DEL C:\ProdAEandAEXdataBACKUP\AE11.bak'
exec master..xp_cmdshell @sql

Step2: Copy production database to development:

declare @cmdstring varchar(1000)
set @cmdstring = 'copy \\Share\SQLDBBackup\AE11.bak C:\ProdAEandAEXdataBACKUP'
exec master..xp_cmdshell @cmdstring 

Step3: Restore by running .sql script

SQLCMD -E -S dev-erpdata1 -b -i "C:\ProdAEandAEXdataBACKUP\AE11_Restore.sql"

Code that is within AE11_Restore.sql file:

RESTORE DATABASE AE11
FROM DISK = N'C:\ProdAEandAEXdataBACKUP\AE11.bak'
WITH MOVE 'AE11' TO 'E:\SQL_DATA\AE11.mdf',
MOVE 'AE11_log' TO 'D:\SQL_LOGS\AE11.ldf',
RECOVERY;

Answer 2

I got this error when there was not enough disk space to restore Db. Cleaning some space solved it.
