Question : Automated Restoring of SQL Database and transaction logs in SQL 2005
|
|
I know very little about SQL 2005 or SQL in general but I do follow instructions very well.
I have a SQL 2005 Server with a 8GB Database that backs up nightly to a different SQL Server (it just creates a BAK file on the 2nd SQL 2005 drive E). Also the log file gets truncated as well just prior to the backup.
I was hoping to get some simple instructions on restoring the database from SQL 2005 Server 1 (SQL1) to SQL 2005 Server 2 (SQL2) automatically at midnight every day.
What would happen is the data from SQL1 backups and restores to SQL2 every night.
Then every hour send the transaction logs from SQL1 to SQL2 so if something were to happen to SQL1 then we would at most be missing 59mins worth of data.
Is there a simple way to explain it to me? I do not know many of the terms that SQL uses so please dumb it down as much as you can.
Thank you

I got this off searchsqlserver, you might not be able to follow the link unless you register for free with them.

the best way to automate the restore process is to create a scheduled task, which will be kicked off as needed. The only thing scheduled task change you may need to make is the name of the backup file. For instance, if you are using Maintenance Plans to perform backups, the file name is dynamically created with the database name and datetime the backup started as the file name. A sample script has been included to help you create a scheduled task that does the four items listed above. This is a good way to get all the necessary steps in place to further automate your weekly or daily refreshes of your test or development environments.
Sample script to automate restores
BEGIN TRANSACTION
DECLARE @JobID BINARY(16)
DECLARE @ReturnCode INT
SELECT @ReturnCode = 0
IF (SELECT COUNT(*) FROM msdb.dbo.syscategories WHERE name = N'[Uncategorized (Local)]') < 1
EXECUTE msdb.dbo.sp_add_category @name = N'[Uncategorized (Local)]'
-- Delete the job with the same name (if it exists)
SELECT @JobID = job_id
FROM msdb.dbo.sysjobs
WHERE (name = N'Automated Database Restore')
IF (@JobID IS NOT NULL)
BEGIN
-- Check if the job is a multi-server job
IF (EXISTS (SELECT *
