Restore Database FROM MDF/LDF, Then Apply Transaction Log From POint Of Failure? Is It POssible?
May 18, 2005
If I have a database backup from sunday, and a failure occurs monday... Can the backup .mdf and .ldf files be attached, and the backup log after the point of failure be applied to them?
The problem I am having is it looks like you can only restore from a .bak file, and then apply the log at the point of failure. IT doesn't look like you can restore the .ldf/.mdf files, and then apply the backup log from the point of failure.
Can someone please help? I'm in desparate need of fixing this !
Our backup system has worked ok for us to date. We can restore back to either full saves or up to a certain log (we take log backups on the hour). We've never had to, but wanted to test restoring to a point-in-time with the backup data.
What the system does is generates .mdf and .ldf files, which is essentially a full backup say in the middle of the night. It then creates .bak files for the log backups based on the backup set you want to restore.
I can detach the database and apply the .mdf and .ldf and re-attach the database, but to apply the .bak files I need to get the database into a (recovering) state. I can't seem to do that. Otherwise when I try to apply the .bak files the system says: The log or differential backup cannot be restored because no files are ready to rollforward.
How to apply a .mdf and then apply the .bak files?
I will make it simpler to look...I have DB1 - as backup for day 1LOg1 as backup of logsT1 T2 T3 T4 T5 ...some transaction on day 2Now i backup againDB2Log2I want to restore the database till the point of transaction T3 say. Iknow the time or i assume a certain time.Is this possible .....i tried several options but hand in between forsome reason or the other. How can i achieve my solution. Is there someextra parameter i will require or what....i am wondering now that it isnot at all possible.

Can I use a full and differential backup to restore to a point of time?
Or I have to use full and transaction log backups in order to do a point of time restore?
I found today when I tried to restore a db from another database at the point of time for example 3:10 pm, SSMS automatically select the full backup + the transaction backup that is done at 3:00 pm, but not select full + the differential backup I did at 3:12pm.
So I lost those records entered after 3:00pm.
I supposed it should use the differential backup and restore to 3:10. but it didn't.
In Windows Server 2012. How do I do a System Restore to a previous restore point?I need to install the 64 bit and 32 bit Oracle Client Install for connections in SSIS and to create Oracle Linked Servers.
If you make a mistake it is not fun removing it. Sometimes it corrupts the machine and it is difficult to uninstall since there is not an Oracle Universal installer for Oracle 11g.If you install the 32 bit before the 64 you mess up the machine.how to create a restore point.
We have an Analysis Services database which has 9 cubes. Whenever I do an Archive/Restore it fails giving the following error:
* Unexpected error encountered while updating repository item cannot be found in the collection corresponding to the requested name or ordinal. * Restoration Cancelled * DSO function failed
I am running SQL Server Enterprise Edition Build 9.0.1399 as a default instance on a Windows Server 2003 Enterprise Edition SP2.
Whenever I try to apply Service Pack 2, I obtain the following error:
A recently applied update, KB921896, failed to install
I looked into the other threads but they either discuss community versions of SQL Server or named instances - niether or which apply to me. I also looked but there are no folders named MSSQLSERVER on this machine.
Can somebody Please Help as this is preventing me from deploying a major solution.
I'm trying to figure out why this SQL Agent job keeps failing.
We used management studio, and connected as mydomainmyuser, and developed a script to take a backup file from a network share and restore it. It worked fine in SSMS under that login.
After we got it working , we created a SQL Agent job on the same server to run the script, and set the agent job to run under that account that we tested with.
This is the error message we got:
"Executed as user: mydomainmyuser. Create Database permission denied in database master'.
So, I gave that login the rights to Create Database and Create Any Database. Then the error message changed to:
"Executed as user: mydomainmyuser. User does not have permission to RESTORE database 'mydatabase'. [SQLSTATE 42000][ERROR 3013] RESTORE DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed. "
* I can't use SA for the job account, because the SA account doesn't have rights to see the network folder where the backup file sits, so it has to run under the domain account. * The user is a member of the dbcreator role - and the serveradmin and sysadmin roles * The user is a member of dbowner on the database I am trying to overwrite with the restore * I have given the user the rights CREATE DATABASE and CREATE ANY DATABASE
The only suspicious thing I found was that it appears the server was renamed at one time. When I looked at the login in management studio, I was not able to change some of the rights. On the Securables page, it shows the server name as "MyServer-New", but the server name is "MyServer". It is a replacement, and I suspect that when they did the replacement they named it "MyServer-New", set everything up, then renamed it.
I found this post listed below, and ran the script (shown below), and it showed that the server name was MyServer and the ServerInstanceName is MyServer-New
[URL] .....
SELECT HOST_NAME() AS 'host_name()', @@servername AS 'ServerNameInstanceName', SERVERPROPERTY('servername') AS 'ServerName', SERVERPROPERTY('machinename') AS 'Windows_Name', SERVERPROPERTY('ComputerNamePhysicalNetBIOS') AS 'NetBIOS_Name', SERVERPROPERTY('instanceName') AS 'InstanceName', SERVERPROPERTY('IsClustered') AS 'IsClustered'
I can't reset SQL until the next maintenance window to test changing the server name as outlined in the post.
Am I on the right track with the name change messing up permissions, or is there something else I need to check?
We have received a backup of a database from an external company for a project that we are taking over. We have attempted to restore the database and it fails giving us the error: "Internal consistency error occurred."
We have run the restore verifyonly command with the results: "The backup set is valid." However, I don't have confidence that the verify is telling the complete story.
It appears that the database is restored and the overall restore is failing on the transaction log file.
First off, I appreciate the time that those of you reading and responding to this request are offering. My quesiton is a theoretical and hopefully simple one, and yet I have been unable to find an answer to it on other searches or sources.
Here's the situation. I am working with SQL Server 2005 on a Windows Server 2003 machine. I have a series of databases, all of which are in Full recovery mode, using a backup device for the full database backups and a separate device for the log backups. The full backups are run every four days during non-business hours. The log backups are run every half hour.
Last week, one of my coworkers found that some rarely-used data was unavailable, and wanted to restore a database to a point in time where the data was available. He told me that point in time was some time back in November.
To accomplish this, I restored the database (in a separate database, as to not overwrite my production database) using the Point in Time Recovery option. I selected November from the "To a point in time" window (I should note that this window is always grey, never white like most active windows, it seems), and the full database backup and the subsequent logs all became available in the "Select the backup sets to restore" window.
I then tried a bevy of different options from the "Options" screen. However, every restore succeeds (ie: it doesn't error out), but seems to be bringing the database back to a current point in time. It's never actually going back to the point in time I specify.
My questions are as follows:
a) Is it possible to do a point in time recovery to a point in time BEFORE the last full database backup?
b) If so, what options would you recommend I use? (ie: "Overwrite the existing database", restore with recovery, etc etc).
I again appreciate any and all advice I receive, and I look forward to hearing from anyone and everyone on this topic. Thank you.
We have an order posting stored procedure that's been executing for 14 hours now. This procedure has simple update statements but all the tables updated have triggers which update other tables with triggers and so on. This procedure hasn't commited yet. I have a full database backup from last night and transaction log backup from this morning while it was running. I want to kill this job and restore database from last backup. Only thing I am afraid of is that it will take too long to roll back which I have no estimate of time. Is there any faster way to get rid of all the uncommited transactions? Has anybody rolled back such a massive transaction? Any idea on how long it can take? Can it affect the overall server performance as this is the main production ERP server. I can see in profiler that this procedure is still running and not hung.
Hi guys, just wanna ask about the backup and restore database method. What's the best way for database and restore which able to view all the transaction logs after the database being restored. Currently I backup my database daily for recovery purposes. However, if I restore the backup file at another server and use SQL log application for viewing the prefer database's transaction log, it shows all the previous log had been truncated.
Therefore, I want to know is there any way that able to get the transaction logs after restore from a database backup file? Hope able to get any assistance here as soon as possible. Thank you.
Assuming all windows servers belonging to the WSFC are on the same subnet, will the AG listener become a single failure point in system if all Application servers connect to the AG through the listener? If the answer is yes, what are the options to resolve this issue?
I have two SQL 6.5 servers running independently. Both servers have almost identical databases. For example, we create purchase order in SQL server A. And post the same purchase order # for it's PO Receipt and PO Inspection in SQL server B. How can I apply all transactions entered from SQL server A to SQL server B, and vise versa at end of the day. How can I get help or training for writing codes for manipulating transaction log?
HiI implement a manual standby by backing up Transaction log files everyhourand database nightly and restoring these on a standby server.Every thing works fine but the Transaction log restore fail with errorlistedI am sure the database backup finishes before the transaction logbackupsThanksTYThe log in this backup set terminates at LSN 22927000000763100001,which is too early to apply to the database. A more recent log backupthat includes LSN 22927000000773700001 can be restored. [SQLSTATE42000] (Error 4326). The step failed.
I can't "point in time restore" a test DB if I had only a Full DB Backup (with overwrite option).
Example 12:00 Fullbackup new (overwrite) 12:01 update any rows 12:02 update any rows 12:03 delete any rows 12:05 Transaction Log backup (overwrite) RESTORE: We can't set "point in Time" to 12:01 od 12:02 ???
My database is in full recovery mode. When I have created some full backups of the database, I would like try to point in time restore. Unfortunately, this option is greyed out on the restore screen. What have I done wrong?
I know NOTHING about SQL. I have a SQL 2005 database. I'm trying to restore a point in time. I get the error:
RESTORE FAILED...AMT12-2-13.TRN... CANNOT FIND THE FILE SPECIFIED.
The file exists, and in the proper location. something is wrong with it. Is there any way to rebuild the entire TRN so that a point in time recovery will work?
I have a SQLServer 2005 database running in Windows 2003 Advanced Server environment. I want to restore from the backup to 2 days back point in time. I am using the Microsoft SQLServer Managment Studio. After I pick the file and specify the time I keep getting the error:
System.Data.SqlClient.SqlError: RESTORE cannot process database 'DBNAME' because it is in use by this session. It is recommended that the master database be used when performing this operation. (Microsoft.SqlServer.Smo)
I did a server reboot to clear off any hanging session.Stil I am getting the message. Please suggest.
I have full backup of database at 13:00and another full backup at 17:00.I've made backup of transaction log at 17:05When I try to restore database to state at15:10 (point in time) , the dialogue in Enterprise Managersays that only time after 17:05 is valid.It seems to me that I've done something wrong at 17:05 while takingtrans. log backup.But, again, if I have full backups at 13:00 and 17:00 restoringdatabase to point in time at 15:10 should be possible ?!Any help is appreciated.Pagus

I have lost a table's contents and need to restore them urgently. I backed up the database. I selected the backup set in order to restore it, but the "Point in time restore " was disabled and I couldn't select it to set the time to which to restore.Could anyone tell me the reason behing that? Another interesting thing is that when I backup a database, I only have two options for backing it up, 1. database complete 2. database differential
I make two full backups on Oct 1 and Oct 10. I want to restore the server to a state in Oct 5. So I just do as follows:
1.Perform a transaction log backup on the server on Oct 23. I have never backup transaction log in the past. 2. Restore the server with Oct 1 full backup with NORECOVERY option. 3.Try to restore to the point at Oct 5 12:00, with the transaction log.
But the restore fails and SQL Server said the transaction log does not contain the point. The point is too early. Why? Also my .LDF file is about 13G, but the transaction log backup is only 200MB. Why?
In the hereunder written message I talk about point in time restore.It is now based upon the fact that there are no hardware problems or what soever.I just would like to roll back to a situation of some time (minutes, hoursor what ever) ago.Used to the ingres database a point in time restore can take place UP toany, any, any time since the last FULL backup. (any time up to now !!!)I can't understand why a point in time restore can only be done based upontransaction log backups. The current transaction log is also available in myopinion. (Turn off the power, turn on the power and you will notice that theautomatic recovery is based upon this transaction log file; so in that casethis file is used)That's what my question is about. Is it correct that a point in time restorein a SQL server environment can only be done up to the last transaction logbackup.ByeArno de Jong,The Netherlands.
Is it possible to restore to a point in time without a preexisting full backup? The situation is this:
I have a table in the DB from which an unknown number of records were accidentally deleted. The table in questio has about 2 million records; the user ran a query to delete all records from the table by accident, and cancelled the query after about 3 seconds.
The DB recovery mode is full, so I should be able to do a point in time restore to go back to just before the deletion, but unfortunately, the DB has never been backed up, so I have no backup to work from.
The DB has not been used since the incident, and is otherwise operational, but I need to recover these records if at all possible. All the instructions I've seen for this involve restoring from a full backup first, then restoring the log backup second. Is there any way for me to accomplish the same task?

I have Full database backup upto previous day and transaction logfile of Today transaction. my database has crashed. I have restored previous day's Full backup. I have faced difficulty to restore today's transaction from today's transaction log. What are the steps to restore full database back and one day's transaction log file. Note: there is no differential database backup and transaction backup.
