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.

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

hi all!
can you help me, in which case will i need to Specify a Point in Time, when restoring a database?
for newbee like me, it looks like it's better to restore without Specifying a Point in Time, because i will restore my data, without headache.
can you give me some sort of example when and why to specifying a point in time?
thank you 1000x in advance!

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?

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.
Ryan

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 ???
why

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

Hello,
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,
Joe

I have full Recovery mode.
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?
Thanks!!

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.

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?

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?

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.

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 !
Thanks,dp

I have a database used in SSRS in which I get a backup daily and restore it to database "DATA"
The issue I come across is SSRS has a datareader user(ssrsuser) for access to the "report store" web where users get reports
access gets erased on each restore. Can I add something to my job to restore this user after each restore or keep the settings?
declare @Bakpath varchar(80)
set @bakpath = 'C:EDataExtractedDataextract.bak'
Use Master
Alter Database [Data]
SET SINGLE_USER With ROLLBACK IMMEDIATE
RESTORE DATABASE [Data] FROM DISK = @bakpath --location of .bak file
WITH REPLACE
GO

I have a client that has POS software called Restaurant Pro Express (RPE) from www.pcamerica.com
Their old POS computer had a hardware failure, but I was able to attach the hard-drive to another computer and recover the data. RPE uses a MSSQL database system. However, my client doesn't seem to make backups very often - the last one is dated January 5, 2015.
I was able to copy the C:Program FilesMicrosoft SQL Server folder over which contained the instance as well as all the data files - and has up-to-date information. The instance in the recovered Microsoft SQL Server folder was called MSSQL.1. I installed the RPE software on their new computer, and it too now has an instance called MSSQL10_50.PCAMERICA. The new computer is using MSSQL 2008 R2, while I believe the old computer would have been using MSSQL 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?

UAT environment : SQL Server 2008 R2 SP3 Enterprise Edition
SANDBOX environment : SQL Server 2008 R2 SP3 Standard Edition
I have a database backup (.bak) that was taken from UAT environment that has CDC enabled on some tables. I want to restore that database into my SANDBOX environment which does not support CDC (because of standard edition). The restore process fails due to this incompatibility. Is there any way to restore without CDC (I dont CDC enabled on my SANDBOX; just my data from the backup) ?

Is is true that in SQL Server 7, a point in time recovery can not read the active logs? So that any point in time recovery has to be with in some time frame of the backups of the logs?
Example:
If you have a full backup at 5 am.
Log backups every 2 hours.
You need to recover at 3:55. You would have to go back to your full backup from 2 am and the transaction logs from 6, 8, 10, 12, and 2.
You would lose any work done from 2-3:55pm?

We are using SQL Server 2008 as our database and use Access as a GUI. I am looking to create a form in Access where employees can access their time card and request changes from management. I want to use the format from the attached screen shot for the form. I pretty much know how to do it all, the only point of complication is trying to figure out the easiest way to get the transaction punch record data on employee_punch_record into a format where I can easily populate the form in the horizontal format you see in the screen shot.
I am not super strong in SQL, but figure I can do it using a formatting table of some sort. quick and easy way to move transaction records into a more horizontally oriented record?

On one of our SQL Server 2014 boxes each database has a copy-only full backup made every night, in addition to the maintenance plan schedule of a full backup weekly, daily differential backups and log backups.
When performing a PIT restore in SSMS the restore file list lists the most recent copy-only backup as the full backup to use, not the most recent plan full backup. I noticed that using SSMS 2008 to start a PIT restore on the 2014 box does not have this problem, and lists the correct restore file sequence (ignores the copy-only backups).
