Hi All,
I am trying to restore full backup in Sql Server 2005. I am using the following query to restore full backup.
"Restore database Testdb from Disk = 'C:Testdbfull.bak'
with move 'Testdb' to 'C:DBTestdb.mdf ',
move 'Testdb_log' to 'C:DBTestdb_log.ldf ', norecovery "
The above query is running successfully and database restored. But i am not able to access this database since in the database tab it is showing 'Testdb (Restoring)'
The next day I want to restore the differential database backup so i used the 'norecovery' statement.
please help why it is showing as '(Restoring)'
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?
WE ARE DOWNLOADING THE BACKUP FILE FROM OTHER BRANCH OFFICE AND THE FILE SIZE IS GROWING LIKE HELL SO I AM CHANGING THE BACKUP POLICY TO DOWNLOAD THE DIFFERENTIAL BACKUP FILES EVERYDAY. BUT EVEN THE FILE SIZE GROWS DAY BY DAY UNTILL WE TAKE THE FULL BACKUP THERE. SO I WANT TO TAKE A DIIFERNETIAL BACKUP AND THEN IMMIDIATELY A FULL BACKUP AT THE REMOTE SERVER END. SO MY NEXT DIFFERNTIAL BACKUP WILL HAVE THE DATA OF ONLY PREVIOUS DAY. FOR THIS I AM SCHEDULING A JOB WHICH FIRST TAKES A DIFFERENTIAL BACKUP AND THEN IMMIDIATELY FULL BACKUP EVERYDAY AT 12.00AM. BUT I HAVE A CONCERN.. WHILE TAKING THE DIFFERENTIAL BACKUP ANY TRANSACTIONS THAT ARE TO BE COMMITED WILL NOT COMMIT UNTIL THE DIFFERENTIAL BACKUP COMPLETES. BUT IMMIDIATELY I AM STARTING FULL BACKUP. IS THERE ANY CHANCE THAT A TRANSACTION GETTING COMMITTED IN BETWEEN THESE TWO STEPS. IF SO IS THERE ANY WAY .. NOT RELEASE THE DATABASE UNTILL THESE 2 BACKUPS ARE COMPLETED?? I AM RUNNING IT AS A JOB.. ANY SUGGESTION??
Does the full and differential backups have to be in the same location or can I do a once a week full backup on one drive and everyday differential backups on a different drive?
Currently run a weekly (full) backup and a daily (differential) backup.
When I format the server and rebuild I restored the DB using the weekly (full) backup and all worked as it should.
When I format the server and rebuild I attempted to restore the DB using the daily (differential) backup - I got the following error: 'SPCDBDIF.BAK ' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set. RESTORE HEADERONLY is terminating abnormally. (MS SQL Server, Error: 3259)
I am sure I am not using the differential file properly. What is the proper method to restore a DB and use a differential backup?
Hi sql server experts. This is a beginners question.
Let's say, I run a full backup at 4:30 am it takes usually 35 minutes to finish.
I want to schedule a differential backup to run every hour.
Should I start this job at 5:10 after the full backup finishes? or it doesn't matter? I am confused about timing.
Let's say my full back up takes 1 hour to finish, that means that when the differential backup runs the full backup will be still running, so in case I need to restore the database, can I use this differential from 5:10 or the differential from 6:10.
Same issue with the transactional, the job runs every 30 minutes, should I started after the differential is done?
I am so confused, what happens with the backups jobs that run while other backups are running?
Scenario: - 1. Full db backup 2. Database failure (delete all data) 3. Differential db backup (after 3 hour of db failure)
When i restore full db followed by the differential db backup, it only remains the differential db data.I do not have transaction log backup so that i can restore to the point.
What can i do to restore db that can have full backup and differential backup data?
I create a full backup followed by daily differential backup, when I restore database from the fifth or later differential item, I get the following Error Message:
System.Data.SqlClient.SqlError: This differential backup cannot be restored because the database has not been restored to the earlier state. (Microsoft.SqlServer.Smo)
It seems that there is an error when the fifth differential backup occurred, It's a disaster, how can I do, help!
I'm new to this forum after read a few question error it given me little bit more understanding. But here's my problem I was create a database implement some tables than make a 'Full Backup' and input information on the table before make a 'Differential Backup'. I don't want restore a full database and just want to recovery specific table were deleted or removed. Please help........
Message show error:
Restore failed for Server 'SALES18'. (Microsoft.SqlServer.Smo)
Additional information:
System.Data.SqlClient.SqlError: The log or differential backup cannot be restored because no files are ready to rollforward.
My company needs to move a 30 Gig SQL Server across the country as soonas possble on July 1. Turns out moving the full db across the networktakes a few hours.I'd like to move a full copy of db a week ahead of time, and then justmove either a differential backup(s) or transaction log with with theweek's new data on July 1.Can anyone suggest the best strategy for doing this? Currently we'redoing a differential backup each hour on the db, and dumping the txnlog each night.Many thanks,Burt
I want to set a full and differential backup to one database in sql server 2000. Is there a way to set both full and differential to just one database.
i want the full backup weekly once and differential every day to set up.
After some advice - I have a SQL Server 2005 database which is part of an anti-virus setup. The main database is 25Gb is size, and it is running in simple recovery mode. There are two backup jobs in place, one to do a differential backup each Mon-Sat, and one to do a full backup on Sun. Although the backups do get done they are taking 5 hours to do. Any wiz out there care to suggest what the problem is, I would've though that maybe an hour was more acceptable ?
I have done a full backup on 3pm, and a differential backup on everyday 5pm.
I try to restore it back in my testing server and i encounter the problem in restoring the File3 and i try to restore the File 2 and it is okie. Can i know wat is the problem usually cause this error? Thank you
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...
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.
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?
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?
After I restore a database with SQL the database I cannot access it. However, after restoring using Enterprise Manager I do not have the same problem. The message I get is:
Database 'les_test' cannot be opened. It is in the middle of a restore.
The code I am trying to use for the restore is:
RESTORE DATABASE les_test FROM DISK = 'c:MSSQL7BACKUPiztrobeta_db_200012011201.BAK' WITH NORECOVERY, REPLACE, MOVE 'biztrobeta_PRI' TO 'c:mssql7DATAiztrobeta_PRI.ndf', MOVE 'biztrobeta_FGE_Dat1' TO 'c:mssql7DATAiztrobeta_FGE_Dat1.ndf', MOVE 'biztrobeta_FGX_Idx1 ' TO 'c:mssql7DATAiztrobeta_FGX_Idx1.ndf', MOVE 'biztrobeta_LOG' TO 'c:mssql7Dataiztrobeta_LOG.ldf' GO
I tried changing the status in the master..sysdatabases tables, but the restored database was still not accessible. I tried to do this using the following statment:
UPDATE sysdatabases SET STATUS = 4194316 WHERE name = 'les_test' GO
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?
Is it possible to do a full restore of a database without restoring the full-text catalogs? At the end of each month, we restore a copy of a database for quick access to month-end data with a different name. e.g. we restore the database DBN as DBN1107. Since upgrading to SQL 2005, the restore is failing because it it trying to restore the full-text catalog.

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.
Data got deleted on Friday evening, need to have database restored to FRiday afternoon and also some data has been entered on Monday, which needs to be there.
I know that the differential backup will only back up information that was changed since the last full database backup, but I have process that I need to implement and need to know if differentials will work.
1. Perform full database backup on Sunday. 2. Perform differential backups Monday thru Friday (twice a day). 3. Perform a database restore on the following Sunday from the backup taken on the previous Sunday. 4. Perform differential backups Monday thru Friday.
At this point I would repeat steps 3 and 4 for the following weeks.
My question is this. Since I didn't actually perform a backup in step 3, but instead performed a database restore, will the differential backup in step 4 backup all of the information changed since step 1??..or will it backup all of the information changed since the restore in step 3? I'm hoping it will only back up the information changed since step 3.
