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?

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

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?

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.

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.

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

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).

The space allocated to the Log in question is 180 GB. During this time period I was running TLog backups every 5 minutes, yet the log continued to chew through to 80 GB used, even after the process was complete and a final TLog backup had been taken. It continued to stay very large until the Full backup was complete -- or something else that I'm unaware of completed. Like every other DBA I typically take a TLog backup to shrink the log, but what appeared to be the case here was the Full completed and it released the used log space. All said, will Transaction Log backups not free up the log during Full backups?

Afternoon,
I have a few Log Shipped DBs that are working great.
Currently they are set to fire off every 15 minutes 24/7.
My question is this ... I need to get FULL backups of the source DBs in order to restore them on certain Dev boxes.
If I were to execute the full backup on one of these Log Shipped DBs ... how would it affect the log shipping process?
Is there a special method to accomplish this?
As a side note, what would be some concerns/issues if in being able to create the FULL backups and not interupt log shipping, I were to create the backup using a 3rd party tool like Quest LiteSpeed?
I sure wish we were on Enterprise, then I could create a mirror and then snapshot off it to create my backups BUT ... that is not the case as we stand today.
Thanks

I'm working on a restore procedure for the case where all MDF filesare missing, but the LDF files are all intact. A full backup is doneevery 24 hours, and a log backup is done every 3 hours. Afterrestoring the last full + log backups, is it at all possible to usethe LDF files to recover data from that point up to a newer point intime?I've found a post which explains how to do this on SQL Server 2000<http://groups.google.com/group/comp...s.ms-sqlserver/browse_thread/thread/3ef5c7cbc0a83334/f3b0c70811d35ed7>, but step 4fails with the following error message:BACKUP LOG cannot be performed because there is no current databasebackup.

I queried sys.databases in one of the sql server and found "is_encrypted" is "1" for four of the databases.
Does that mean that all those 4 DBs are encrypted ?
How to check if the database itself is encrypted or only the backups ?
Note :- I can see backups of key in a particular folder.

Having a lot of problems with backup device creating backups with a new transaction log for each day. This is causing the backups to grow way to fast. Seems to be random with our clients. Created new device backups but getting same problem. A manual backup selecting overwrite all existing backup sets will fix it. But starts the cycle all over again.

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?

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!!

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!

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.

PLEASE 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??
THANKS IN ADVANCE.. :-)
