Backup And Restore(full + Transaction Log)
Mar 10, 2008
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"?

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?

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

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.

Please correct me if I am wrong with this:
I am using SQL Server 2000, when I do a backup I use the database maintenance plan at enterprise manager. I select my database and then I schedule the complete backup and transaction log backup to "everyday at 22:00:00"
My question is, do I really need to do the transaction log backup? If I am not wrong with the complete backup I can already recover all my data, the transaction log backup is useless if done at the same time that I do the complete backup, right?

Hi, I am reading the book of MCTS Self-Pace Training Kit. If I set up the option of Recovery Model in the properties of a database, Does SQL Sever will generate/update the log file per transaction? What is the relationship between Transaction Log files and Recovery? When we want to recover a database, we can use the database's backup. Why we need to keep Transaction Log?
Sincerely,
Julian

Greetings, All -
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?

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.

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?

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

In MS SQL 2005 when you do a Full Backup does it also backup andtruncate the transaction logs or do I need to back the transactionlogs up separately?Thanks.Brian

I am running the following script to attempt a restore of a differential backup:
RESTORE DATABASE AdventureWorks
FROM DISK='C:SQL2005_BackupsAutoBackupsAdventureWorks.bak'
WITH
NORECOVERY
GO
RESTORE DATABASE AdventureWorks
FROM DISK='C:SQL2005_BackupsAutoBackupsAdventureWorksDiff.bak'
WITH RECOVERY
GO
I thought this was the way to do it. It does restore the full backup, but on the attempt to restore the differential backup, I get the following error:
Msg 3136, Level 16, State 1, Line 1
This differential backup cannot be restored because the database has not been restored to the correct earlier state.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
Does anyone know what this means? Do I have to use "with recovery" on the first restore? (The sample I took this from used "with norecovery")
The original backups were done with SQL Agent scheduled jobs. The script for the full backup is:
BACKUP DATABASE AdventureWorks
TO DISK='C:SQL2005_BackupsAutoBackupsAdventureWorks.bak'
The script for the differential backup is:
BACKUP DATABASE AdventureWorks
TO DISK='C:SQL2005_BackupsAutoBackupsAdventureWorksDiff.bak'
WITH DIFFERENTIAL, INIT
All I can say is, it's a good thing I am testing this out with non-critical data, because I obviously don't know what I am doing. (Sorry, I'm primarily a programmer, not a DBA) Can anyone help?
Thanks

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.
Best Regards,
Hans

I am working towards automating the process of testing our backups. For the meantime, I do it all manually - I copy the backup files (full + transaction logs) to our test server and then run the restore script. Once database restored I run the DBCC CheckDB. The results of checkdb I manually upload to our Sharepoint portal as proof that the backup file is intact with no errors.
here are some ideas I have but have not yet tested:
Create a maintenance plan with each 3 jobs:
--> Powershell script to copy the files from Prod server to Test server - add this scrip to Job1
--> Powershell script to restore databases files - add this script to Job2
--> Run the DBCC in powershell (yet to find if possible in PS) - add this script to Job3
I would like to use seperate jobs as to get a report on the duration and status of each job
Would also like to get the results of the DBCC Checkdb as proof that no errors were found for upload to our Sharepoint portal. Dont know if possible via the job.

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.

Using Ola Hallengren's scripts I do a full backup of a database on a Sunday. Then differential backups every 6 hours and log backups every hour. I would like to keep a full week of backups based off the full backup done on Sunday. Is there a way for me to clear out the diff and log folders after the successful full backup on Sunday nights?

I have a database that is just over 1.5GB and the Full backup that is 13GB not sure how this is since we have compression on for full backups and my other full backups are much smaller than there respective databases...Now my full backup is taken every Sunday night and the differentials are taken every 6 hours after the full backup. Now I have been thrown into this DBA role with little to no experience just what I have picked up and read. So my understanding of backups are limited but what I think I understand is that we take a full backup and the differential only captures what changes in the database so my question is why is my database 1.5GB but my differential is 15.4GB? I have others database that are on the same instance and don't seem to have this problem. I also just noticed that we do not rebuild the index before a full backup like we do on other instances...

If my backup starts at 8PM and take 1 hour to complete, will the changes made to the database during that hour be captured in the full backup?
Stated another way, will my backup be a snapshot of:
a) 8PM when the backup started
b) 8PM with some of the changes made between the hour
c) 9PM when the backup finished?
Anybody know the exact way SQL Server handles that logic?
Thanks,
Marc

Hi
I am using the Simple recovery model and I'm taking a weekly full backup each Monday morning with differentials taken every 4 hours during the day.
On Wednesday afternoon, a programmer ran a process that corrupted the db and I had to restore to the most recent differential. It was 5pm in the afternoon and a differential backup had just occured at 4pm. No problem, I figured.
I restored the full backup from Monday morning and tried to restore the most recent differential backup. The differential restore failed. Since I had used T-SQL for the initial attempt, I tried using Enterprise Manager to try again.
When viewing the backup history, I see my initial full backup taken on Monday plus all the differentials. BUT, on closer inspection, I noticed another full backup in the backup history that was taken early Tuesday morning. I can't figure out where this Tuesday morning full backup came from. It wasn't taken by me (or scheduled by me) and I'm the only one with access to the server. My full backups are usually named something like HCMPRP_20070718_FULL.bak. This erroneous full backup was named something like HCMPRP_03a_361adk2k_dd53.bak. It seemed like it was a system generated name. Not something I would choose. To top it off, I could not find this backup file anywhere on the server and when I tried to restore using this full backup, it failed.
Does anyone have any clues as to where this full backup might come from? Does SQL Server trigger a full backup on its own if some threshold is reached?
I ended up having to restore using the differential taken just before this erroneous full backup and lost a day of transactions.
Any insight is greatly appreciated.

Hello,
I have MS SQL 2005 server with 300+ databases on it. The application is set up that way that it creates a new database as needed (dynamically). Do not ask me why - I hate this design... So, it can create 3-4 databases a day (random time).
I've scheduled full backup of all databases to run once at night, and it runs just fine. Besides that, I have scheduled tran logs backup of all databases to run every hour. This backup fails from time to time with the following error:
Executing the query "BACKUP LOG [survey_p0886464_test] TO DISK = N'D:\backups\log backups\survey_p0886464_test_backup_200708072300.trn' WITH NOFORMAT, NOINIT, NAME = N'survey_p0886464_test_backup_20070807230002', SKIP, REWIND, NOUNLOAD, STATS = 10
" failed with the following error: "BACKUP LOG cannot be performed because there is no current database backup.
BACKUP LOG is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
So, I think what happens is since my full backup of all databases are scheduled to run only once at night, and tran logs every hour, when new database is created during the day, there is no full backup for it, that is why tran logs backup fails. Becuase after the failure, if I run full backup again, then tran log runs just fine afterwards.
I am new to MS SQL Server, I am mostly working with Sybase IQ. Do you know if I can "trigger" full backup every time when new database created to avoid tran lof failure?
Or is it possible to schedule full backup to run if tran log backup fails?
Any advice will be much appreciated.

If I create an adhoc db backup that takes, say 30 miuntes to complete, should I suspend the tran log backups that run every 10 minutes, until the full backup is complete?

Hi,
Using SQL Server 2005, we have a 2.8Gb database under the Simple recovery model. The database contains ~50M rows and each night ~60k rows are loaded(appended) to the database by a SSIS task.
We configured a Maintenance Plan which is executed once a week to perform a full backup of the database. The resulting backup file is ~2.8Gb, as expected.
We also configured another Maintenance Plan which is executed every day, a few hours after the SSIS task is executed, to perform a differential backup. To our surprise, the resulting backup file is about the same size as the full backup, ~2.8Gb when it should only be a few MB (only 60k rows are added to the database)
When we launch the "Restore Database" wizzard we clearly see the different backup set, Full and Differential but they all have about the same size (same for the physical backup file on disk).
Is there anything we are missing, why are the differential backup that big?
Thanks for any advice.

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.

Hi:
I have 30 databases on sql server 2005 that I need to do a full backup every morning at 7:00 and tran log backup every 30 minutes until 7:00 PM. If I create a maintenance plan for a backup using the wizard I have the option of starting a full backup at 7 am and then an option of doing tran log backups every hour using a different schedule. I plan on selecting the option to create a different folder for every database. I just need to confirm that in this way the way to restore the data would be
1. to restore a full backup
2. apply all the tran logs depending on the time they want to recover back to.
I just think this is the easiest approach to have 30 databases on the same backup scheme instead of creating a separate backup device for each database and doing a full backup on that device and appending all tran logs to that device which means just 1 bak file versus the above strategy with a number of tran log files. Please advise.
Thanks
