SQL Server 2008 :: Restore To Point In Time DURING Differential Backup

Feb 25, 2015

We have a 1TB Database. Our backup strategy looks like this.

Weekly Full backups - Saturday 10pm. (Takes anywhere between 5 - 9 hours)
twice Nightly Diffs (8:30p and 2:30am - Mid week this takes roughly 1.5 hours)
Hourly Log backups starting at 4:00am until 11pm.

I have an issue where I need to restore to 3:00 today. If my (2:30a)Diff is still running at that recovery point.

I am getting an error when trying to restore Full/2:30a Diff/4a Log with a stopat 3:00a.

Error telling me my log backup is incorrectly formed.

Can I, in fact, restore to this point at all? Do I need to go back to my previous Diff (8:30p) and restore the logs, if so, which ones?

My nighttime Diff ran from 8:30 - 10p.

I have logs at 9p, 10p, 11p, 4a

SQL Server 2008 :: Restore Database To A Point Of Time

Sep 1, 2015

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.

Restore To Point In Time WITHOUT Full Backup?

Oct 27, 2007

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?

SQL Server 2008 :: Restore A Point Between Two Full Backups

Oct 23, 2015

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?

Is Point In Time Recovery To A Point Before The Last Full Database Backup Possible?

Mar 26, 2008

Hello all,

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.

Differential Backup File Fails To Restore.

Jul 19, 2007

We are doing the following steps:-

1. Weekly Full Bckup

2.Daily Differential backup

3.hr Log back up

The following command works fine for all the Backups. it means backup file is fine.

RESTORE FILELISTONLY from DISK = 'D:BackupewDB_ full.BAK'

RESTORE HEADERONLY FROM DISK = 'D:BackupewDB_ ull.BAK'

RESTORE LABELONLY FROM DISK = 'D:BackupewTest_full.BAK'

RESTORE VERIFYONLY FROM DISK = 'D:BackupewTest_full.BAK'



Also The full back up restoration works fine:

RESTORE DATABASE Test3 FROM DISK = 'D:BackupewTest_full.BAK'

WITH MOVE 'Test2_Data' TO 'F:MSSQL2KMSSQLdataTest2Net_Data.MDF',

MOVE 'Test2_Log' TO 'F:MSSQL2KMSSQLdataTest2Net_Log.LDF',

NORECOVERY

GO

/* RESULT :

Processed 1032 pages for database 'Test3', file 'test2_Data' on file 1.

Processed 1 pages for database 'Test3', file 'test2_Log' on file 1.

RESTORE DATABASE successfully processed 1033 pages in 1.907 seconds (4.433 MB/sec).

*/

But While restoring the Differential file it throws error:

RESTORE DATABASE Test3 from DISK = 'D:Backupew est2_Diff1.bak'

WITH NORECOVERY

GO



Msg 3136, Level 16, State 0, Line 1

Cannot apply the backup on device 'D:Backupew est2_Diff1.bak' to database 'Test3'.

Msg 3013, Level 16, State 1, Line 1

RESTORE DATABASE is terminating abnormally.

I checked the SQL Server Log no error msg corresponding Differential backup restore.



I don't know how to proceed further.Can any one guide me how to over come this..



Thanks !

Error Attempting Restore Of Full/differential Backup

Sep 13, 2006

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

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

Thanks a lot,

I just accidently deleted a handful of records out of a table about 10 minutes ago. My last backup was last night.

Can I go back 10 minutes ago for a specific table? If so how... DO I need to backup now, then use the trans-logs to recover up to a specific point?

Point In Time Restore Part II

Jul 20, 2005

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.

SQL 2012 :: Restore MDF Then Apply Logs / Point In Time

Jun 6, 2014

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?

SQL Server 2008 :: Restore From A Backup With Wildcard?

RESTORE DATABASE [XXXData] FROM DISK = 'C:folderExtractedDataapp_XXX_backup_15_01_28.bak' --location of .bak file

I would like to do something like

SQL Server 2008 :: Replication Backup And Restore

Aug 5, 2015

SQL Transaction replication, specifically SQL backup and restore Transaction replication. So Scenario,

S1 = Primary Server 1
R1 = T - Replication Server 1
R2 = T - Replication Server 2

So we have S1 replicating to R1, and we want to build another subscriber which is R2.

Can I take the Replicated Database from R1, backup it up, then restore it to R2, and create the publication/subscription?

Will that work? if not, is there an easier way to avoid the snapshot? the reason i ask this is because we do have replication snapshot, but takes long. One of my Colleagues stated he tried this, however replication made duplicate rows on R2, which is why he had to use replication snapshot.

Log Backup In Point-in-time Recovery

Aug 10, 2000

Hi Everybody:

We plan to do point-in-time recovery for certain databases. We plan to do Complete Database Backup every night and transaction log backup every two hours from 8:00 AM to 5:00 PM. I have following questions regarding the log backup.

1. There are two type of backup 'Append to media' or 'Overwrite'. If I choose 'Append' for log backup, is that mean I only need to restore database against last log backup file because all previous log backups have been accumulated there?

2. Can I automatically truncate log after the backup is done? How I can do it?

Thank you very much.

I removed the account from sysadmin and limited it to dbcreator and public but the job fail.

How to setup an account so that people who know the service account password can't log in with that account and read db information?

Point In Time Backup (impossible For Some Points?)

Sep 21, 2006

Hello,I am using SQL Server 2000 with SP4. I have a database with two fullbackups at 4:00 PM and 5:00 PM and a transactional log backup at 5:30PM. Is there a possible way to do a point in time restore to 4:30 PM,that is between two full backups?When I try to use the transactional log backup that is taken at 5:30, Ican never specify a time before 5:00 PM. Is the transaction logtruncated at each full backup? If so, even if you take transactionallog backup every ten minutes, and full backups every once in a while,there will be some point in time which cannot be recovered to, namelythe time between a transactional log backup and a full backup. Take alog backup at 4:50, and full backup at 5:00 and you can never recoverto 4:55, can you?Any insight on the topic will be appreciated,Regards,M. Baris Caglar

Point-in-time Backup Of Database && Filesystem

Jul 20, 2005

We're considering purchasing an application,which stores some data in the filesystem, andsome data (meta data and links to files) inMS-SQL.We need to be able to create a backup whereinthe database and files are "in synch" (in other words,in a consistent state). We need to maintain the"referential integrity" between database and files.What I'm thinking of is something like this:1. stop the application server2. set database to readonly (flush updatesfrom cache to disk)3. backup database to disk files4. back up application files and backup files.(We could use "snapshot" capabilities of our diskhardware, so that the backup could run against thesnapshot; that would minimize downtime.)4. set database to read_write; restart app serverRecovery scenario would be:1. Stop application server.2. restore application files and database backup files3. restore database from disk backup4. restart application serverIs there a simpler way to get a "point in time" backupof application files and the database?

SQL Server 2008 :: Test Backup Restores (full And Log) - Restore Databases Automatically?

Apr 4, 2015

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.
