Restore Of Transaction Log Backup
Apr 18, 2008
Hi All,
I am facing one problem.
My Testing Server is down. I have taken full backup 1 hr backup. After that i have taken additional 5 TL backups. All the backups were moved to different server.
Now DB Server is corrupted. Now i have to rebuild the Database Server from the available Backup and TLog Backup.
But i have reliased that all the Transaction Log backup are having no naming convention in File name.
I am wondering after restoring full backup, which tlog backup i should use for next restore.
Thanks in advance.

I neglected to backup the transaction log as part of the process of backing up the database. Now i only have the backup file for the database and no transaction log backup. When i try to do a restore on the database, i get the error on a "tail log missing" message (which i'm assuming is that it's looking for the t-log backup?).
Is it possible to restore or even restore to a new database? I'm only looking to retreive data from 2 tables within the backup file.
Thanks!
SQL Server 2005 on Windows 2003 Server x64.

Actually instead of creating initial snapshot ,I thought of doing Transaction Replication in 2005 with backup/Restore. Everthing worked fine for DML changes which is being replicated to subscriber.
But my question is:
1)In 2005, DDL changes also replicate by default, Why i am not getting that feature while doing tran rep with backup/Restore?
Any replication Experts?

I have this database "DB1" which is in FULL recovery mode.
I run full daily backup -Monday to Saturday
DB1_Mon.bak
DB1_Tue.bak
DB1_Wed.bak
DB1_Thur.bak
DB1_Fri.bak
DB1_Sat.bak
Come Sunday - for the first time I have run transaction log backup.
DB1_Sun.trn
And now, I need to restore DB1 - but the only full backup that I have is the Monday - "DB1_Mon.bak"
Is my database complete if I restore only "DB1_Mon.bak" plus the "DB1_Sun.trn"?

hi, I would like to know the correct reaction for a crash in both senarios.
First senario,
I made a full back up at 6 am , then scheduled sql server to make transaction log back up every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 12:30. How would I resotre the data in the first senario....Can I restore the full back up done at 6 am then restore the last transaction log backup ( which is 12 Noon ) . I am not sure If I need to resotre the whole tran from 6 am till the time it was crashed.
Second senario,
I made a full back up at 6 am, then scheduled sql server to make Incremental backup every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 3:00 pm. How would I resotre the data in the second senario. ....Do I restore the full backup at 6 am then restore each incremental backup backwords ( 2,12,10,8)
AS you can see, I am not sure how to deal with this issue, I do appreciate your feedback.
Best regards
Ahmed

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.

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.

I am looking for a SQL Backup/Restore tools which can restore multiple environments. Here is high level requirements.
1. We have 4 DBs, range from 1 TB - 1.5 TB Each Database. When we restore to QA, DEV, or Staging, we usually restore 4 of them.
2. I am looking for the speed to complete restoring between 1 - 2 hours for 4 DBs.
I am evaluating the Dephix Software but the setup is very complex and its given us a lot of issues with Windows Authentions, and failure in the middle of the backup. I used Guess Software many years ago but can't find it on the web site any more. Speed is very important for us mean complete restoring as fast as possible. We are on SQL 2012 and SQL 2008 R2.We are currently using NETAPP Technology and I have Redgate Backup Tool but I am mainly looking for fast Restore Process.

We take a full backup in the early morning and hourly transaction log back during the working hours for one database in the production server. The application team made certain changes to the design of the said database in their development server. The backup from the development server was restored to the production server during working hours. After the restoration should we take a full backup before next transactional logbackup? Would the transactional log backup with out a full backup after the restoration of a database be valid?

I should restore a SQL Server 2005 Database from backup. The backup contains three files, named user.bak0, user.bak1 and user.bak2.
How is the syntax of the restore filelistonly and the restore database ... ?
I usualy write
restore filelistonly from disk = 'path and filenam.bak'
restore database. zy
from disk = 'path and filename.bak'
with replace,
move.....
move....
This works but I cannot use it with a splitted backup file. The files are much too big to put together to one file.
Thanks in advance for any help.

Hello, everyone:
I just heard that for restore purpose, ths full backup and transaction log backup should be from one maintenance plan. Otherwise transaction log backup files cannot be restored after restoring full backup files.
Is it true? Can anyone offer official documents?
In my system, full and transaction backups are from one maintenance plan. Restores are doing fine. I am not sure that ideal is true or not.
Thanks

How do I restore from a transaction Log? I use 2 separate database devices for my database (Data & Log) If data is corrupted at 3PM, can I just go and do a
LOAD TRANSACTION DatabaseName
from the LogDeviceName
StopAt 2:59
When I try to run that, it doesn't work. There is no option in the REstore Interface to specify to restore from only the transaction log. Do I need to DUMP the transaction log several times a day in order to do the restore?
Thanks!

Do you backup transaction log periodically? If not, sorry for that.

I need help ASAP!
For some reason, we lost a dozen of our tables with valuable data. could be a virus or something that cleared out our data.
The last backup we have is last night at 11PM. If we recover from that backup, all the users lose all of today's work!
Is there a way I can just roll back the transactions from today?????!
I'd really appreciate any help urgently

Dear All,
We accidentally overwrite some data in our DB. Bad news is we never back-up our DB. However, the system are set in full-recovery mode. From website and book, i found that it's possible to recover back the data using "Recovery DB to a Point Time" but when we try it, we found that it cannot work without any backup data.
Anyone know how to resolve this issue?
Please kindly help.. Thanks alot!!

Is my concept about using the transaction logrestore wrong?Thanks in advance.

i have been doing tests and i cannot manage to do this. here is what i have done and am trying to do:
I created a full backup of the adventureworks database
I made some updates to tables.
I created a differential backup.
I done an update update to another table, dropped a table, and done another update.
Lets say in a production envrionment i just realised the table was dropped and i wanted to go to the transaction just before the table was dropped. is this possible, or are all transactions in the log going to be lost? All i have found remotely related to this are marked transactions, but they are not what i am looking for. i want a list of transactions in the log and be able to select one as the backup point ( via SSMS or TSQL). i am not looking for a point in time restore.
Thanks all

Hi
We have a database on sqlserver 2005 on a schedule for transaction log backups is in place already which is happening at interval of 30mins.All these transaction logs are appended to file called 'BKP' on E drive of our server. Now i have to configure logshipping for this database.Normally logshipping process will backup the transaction log,stores it in a shared folder on primary server and then copies the backupfile to another folder on secondary server and then restored ..plz correct me till now if im wrong.Now let us say our normal trans log backup schedule is as follows
T1 at 9.30am
T2 at 10.00am
T3 at 10.30am
T4 at 11.00 am
Now i decided to schedule the log shipping transaction log backup interval once in 30mins and start transaction log backup at following intervals
T11 AT 9.45am
T22 AT 10.15AM
T33 at 10.45AM
T44 AT 11.15AM
So T11,T22 etc these backups are restored on standby server sequentially.
Now if Primary database goes down at 11.25am , then do i have to restore the Tlogs T1,T2,T3,T4 and make the Primary database up or i should restore T1,T11,T2,T22,T3,T33,T4,T44 for making my primary database UP..

Hi,
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.

I am currently running MSSQL on DB1 server with 12 DBs
I am running a full backup nightly at 8:00pm and coping it over to DB2.
I am sending transaction logs every 15 minutes to DB2.
Is there a script or procedure for rolling in all the logs once the restore is finished. I realize the basic way to do this is here
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/howtosql/ht_7_backpc_7veh.asp
But writing a script with say 22 files each for each db is fairly time consuming.
I have contemplated writing a script that takes the content of the logs directory, parses it based on db name and builds the sql statements but did not want to go through all of it if someone else has already done the leg work.
Any help on this would be appreciated.

I had to replace my hard drive which was going bad. I reinstalled Sql 2005 and now need to restore the backup that I have. I selected Restore Database and chose From Device, and selected the backup location on J: drive and selected the backup file which has no extenstion. I checked the checkbox next to the backup set to restore. Click OK and then I get this error message:
Restore failed for Server
System.Data.SqlClient.SqlError: Directory lookup for the file "C:Program FilesMicrosoft SQL ServerMSSQLdataMyDB_Data.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.Smo)
I don't know why it is looking for a MDF file as this was never in the Backup folder. Can someone please help me on this? I thought I was doing the right thing making a backup all along and now I can't restore it!

Hi I am operating my databases under "trunc log on checkpoint" mode as I do not need point of failure recoverability.I was performing a recovery test using a backup which resulted in it being unsuccessful .Error Message received was
"Recovery has failed because a nonlogged operation could not be redone.Use the RESTORE statement to restore all data in filegroup PRIMARY to a pt beyond the nonlogged changes"
Isnt sql*server supposed to prevent a non-logged operation while a backup is in progress?Also how do i prevent such a situation from recurring.
If i switch to single user mode before a backup how do i prevent exisiting users from accessing ... without bouncing my sql*server?
