Problems Testing Db Restore, File Based Backups
Aug 18, 2006
I'm trying to test out a restore scenario for a large database. It contains several files, each one is backed up when we are finished inserting data into it. No changes are made to the data after insert. All changes happen in tables in the primary file group.
So, I backup the primary file, the log, the first "partitioned" file, the log, the next "partitioned" file, the log, etc, etc, etc. Now, I delete one of the tables residing on one of the partitioned files and want to restore it. For arguments sake, let's say I have a primary file, and 5 partitioned files. I delete the table which was on file 3.
I'm having trouble wrapping my head around the steps to restore under these circumstances. I thought I understood it but, apparently not. When I try to restore, I'm told I must first backup the tail of the log. Having done that, I restore file 3, and all subsequent log files. Now, I'm right back where I was (missing the deleted table). When I try to roll back to a point in time before the delete...it claims to be successful but, nothing perceptable is different...??
Can someone help set me straight here?

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.

Hi everyone,
I have a problem with my MS SQL Server 2000 (SP2). My task is to restore a backup from a database on another computer.
The server makes a backup everyday. If this server gets a hardware problem there must be a chance to replace it by another server which is made by the backup files.
In this scenario I don't have the possibility to copy the whole folder of the old server.
Is it possible to restore the bakup so that the new server looks like the old one?
Thanks for every response.

Our DBs are set up to do a full backup once a day (late at night) and then transaction log backups during the day at shorter intervals.
I want to setup a dev database on the same server. I want this database to be an automatically restored copy of the live database. So every night, after the full backup of the live DB, I want to restore the live DB to this dev DB.
Can this be automated? Can the restore automatically stop the dev database in case some open connections exist?
Is there a better way to do this?

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?

So I'm testing some things in our new servers and was trying to restore a database from some striped backup sets. We have 4 files for our backups and restoring the FULL backups with no recovery worked beautifully via SSMS. But when I tried to restore the differentials (also striped across 4 files), the GUI gave me this error:
Unable to create restore plan due to break in the LSN chain.
How to locate when the break happened and I came across this article about how this is an SSMS 2012 bug.
So I tried the advice in this article to attempt a restore via Files and Filegroups, and ended up with the below error:
EDIT: Picture is attached if it is not showing in post.
I was able to restore via T-SQL, but I want to also be able to restore through the GUI.

how to restore database backups with different recovery fork. I have 1-full backup 2-diff backups and 10-tran backups. My prod database in mirror, so after error, switched to mirror with "allow_data_loss" option. And now I have full and diff backup with one recovery fork GUID and other backups with another GUID.So the question is, how to restore all this backups if in middle of restoration will be different recovery fork.Tryed to restore log backups with new fork guid and got error:This backup set cannot be applied because it is on a recovery path that is inconsistent with the database. The recovery path is the sequence of data and log backups that have brought the database to a particular recovery point. Find a compatible backup to restore, or restore the rest of the database to match a recovery point within this backup set, which will restore the database to a different point in time.

I'm not sure when it started, but...
It seems that very recently, the backups made during a nightly ArcServe tape backup procedure are showing up in the restore window on our SQL server. We don't want that! The application group makes it's own backup's to disk, and we want to see only them in the restore window.
(The tape ackup is a redudnant process, to be used if one of our on-hand disk backups are bad or non-existent, or if the DB needs to be recovered from an older date.)
What made the ArcServe files show up? How can we stop SQL server from thinking tyhat they are part of the backup set we are conccerned with?
Thanks.

We had our backups backing up to the server where the databases reside. Now I modified the backups to backup to a file share. Now when we try to restore from the file share the restore fails, so we have to copy the backup to a drive on the server and recover for there. Should I be able to restore directly from the file share (using the gui)? Do I need to change something else to modify the default backup drive?

I am trying to create a job that would backup a DB dynamically to a different folder based on the week day. So if it's Saturday, backup to folder Saturday.
I have this
DECLARE @BackupLoc nvarchar (100)
DECLARE @DayOfWeek nvarchar (100)
set @BackupLoc = N'D:Backup'
set @DayOfWeek = (SELECT DATENAME(dw,GETDATE()))
set @BackupLoc = @backuploc + @DayOfWeek
[Code] ....
But it's giving me permission errors, although the AGENT and MSSQL service accounts are members of the local admins group.

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 am testing some maintenance tasks sql commands such as index rebuild, index reorg, update statistics and db integrity check on a SQL Server 2014 Database. This is a new non-production vendor database (DB Size 500 GBs, Log Size 25 GBs) which eventually will be created in production. Currently, it is in full recovery model and without log backups. The database has a whole lot of indexes. I am just trying to rebuild and reorganize all the indexes (that need it), in addition to trying to get an idea of how long these maintenance task will take and the space needed in the log file to complete these tasks/commands. I would like to execute these tasks manually (the first time) to gather the duration and space required information. Eventually, I would probably schedule a weekly job to perform this maintenance.
I ran the index rebuild task on the database and noticed that the log file grew by over 50 GBs. I killed the process and truncated and shrunk the log file back down.
1. Does the index rebuild, index reorg, update statistics and db integrity check commands all use the log file?
2. Does Indexs Reorg have less impact on log file then Index Rebuild?
3. Should a truncate log and shrink log file be performed after these maintenance commands?
4. Should a full database backup be performed after these maintenance commands? Or before the maintenance commands?
I have read and understand that shrinking is not good for the database (could lead to more fragmentation and more data file growth when data is added) and I know about rebuilding indexes when fragmentation is GT 30% and reorganizing indexes when fragmentation is GT 5% and LE 30%.
Since this is a non-production database maybe I should set the recovery model to simple, run the maintenance commands and leave the database in simple recovery model unless the vendor needs it in full recovery model for some unknown reason.
5. With the simple recovery model the log file should be reused in a circular manner and not grow during these maintenance tasks. Is this correct?

I've been looking through this forum and can only guess that SQL2005 has changed in how backups and log file growth issues are handled. I tried the All Tasks feature from the GUI to perform a backup, however, the Truncate the Transaction log feature is greyed out so I can not select it. In SQL2000 I used the following to backup my databases and the log files were never a problem:
BACKUP DATABASE [DSS] TO DISK =
N'G:MSSQLBackupDSSbackup.BAK'
WITH INIT , NOUNLOAD , NAME = N'DSS backup',
SKIP , STATS = 10, NOFORMAT
Could someone assist me with a proper T-SQL to place in a job to backup my database and keep the log file under control and / or explain why the Truncate transaction log feature is greyed out?
Thanks!

HI
I am trying to find a pure web based backup restore tool that can be used on MS SQL 2000.
I have found a few that claim to be web based, but then it tells you to log into your MS SQL server and make some adjustments.
I know that microsoft Enterprise manager comes with a backup / restore tool. but 1) i dont want to have to install a complete copy of 2005 server, and 2) i dont hav ethe physical space to do it right now anyway. all i need to do is move 2 databases from one account to another.
thanks

I run two different types of backups on the same database.
A monthly full and nightly diffs appending to the same full file - file 'A'
A weekly full with 10 min trans log backups appending to same file - file 'B'- during working hours.
2 strategies, 2 backup files.
These are new strats that have gone live this week - tuesday in fact. The monthly and weekly both ran fine on tuesday as did the nightly diff and all the TS backups througout the day. last night - Weds - the nightly diff failed with the following error:
"
Executed as user: <USERNAME>. Cannot perform a differential backup for database "objectstore", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option. [SQLSTATE 42000] (Error 3035) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
"
Whilst the error is perfectly legible I dont understand what its implying - cant I add multiple Diff backups to the same full backup OR is my weekly / 10 mins on the same database (but to a diff backup file) ballsing things up for me somehow? If this is the case how come everything ran fine on tuesday night?
Any help gets beers.
THanks

I need to move specific files from a server to another server on a monthly basis. There are hundreds of files that are in the source directory and I need to move approximately 40 of those to the destination server. I would like to easily add or delete the file list as needed. I have seen where several variables were created for for each file name (and one for the path) and the ForEach Loop would go through them. With 40 or more I was thinking that I could make a connection to an Excel spreadsheet or text file with a record for each file name and read in and and move to the next record and make that value become the content of a "FileName" variable. Then if I wanted to add another file name I could just add another record to spreadsheet/text file or remove and the package would handle automatically....

I have a task for which I have to load csv file from a shared directory into sql table. Right now I'm stuck with a road blocker, The issue is the shared drive contains all the history files as well and I have to pick only the latest file. But I cannot identify latest file based on the file name because it doesn't contain any date in the file name. However by seeing file properties I can pull latest file.
Sample file name: XXX_XXX_XXX_XXX_XXX-5814201.csv
Is there any way we can automate this in SSIS with file properties and picking the latest one?

We have a set of databases some are fully read-only others have read-only file groups, is there any way to restore backups of these taken on an MSDE 2000 to an SQL Express 2005 instance?
When doing the inplace upgrade we change these to read-write before the upgrade and set them back after the upgrade.
These databases are used in the field by customers althought the controlled upgrade requires a backup before (and blocks if it fails) and tries a backup after if the post upgrade backup fails (due to disk space) we might need to recover from this odd situation.
The only solution I have is install MSDE some place restore to this then do the controlled upgrade again, any other ideas?

My customer got a total hard drive failure.After sending it to drive recovery specialist we were able to recover the LDF log file (MyDB_0.LDF).But the MDF file was completely destroyed (MyDB.MDF).They have a good full backup from a month ago.
1) Installed SQL Server 2012 on a new PC
2) Created a new database of same name (MyDB) - with same MDF and LDF file names as original
3) Took the new database offline
4) deleted the MDF and LDF files of the new database
5) put "MyDB_0.LDF" in the place of the LDF file I just deleted
6) put the database back on-line
7) after hitting F5 to refresh databases - it shows "MyDB (Recovery Pending)"
8) tried to do Tail Log Backup with this command
BACKUP LOG [MyDB] TO DISK = N'C:BACKUPMyDB_TailLog.bak'
WITH NO_TRUNCATE
And I get this error...
Msg 3447, Level 16, State 1, Line 3
Could not activate or scan all of the log files for database 'MyDB'.
The sad thing is I know we can get this data back using ApexSQL-Log. I can see all the transactions since the last full backup in this program - so the log file is not damaged. But my client doesn't want to pay the $2000 fee for this software.There has to be a way to restore this data, without having to purchase a third party tool.

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?

Database file or filegroup method was used to perform the backup and now i tried to restore that into different server by using SQL Server Enterprise Manager.
I got this error message:
"The database you are attempting to restore was backed up under a diffrent sort order ID (54) than the one currently running on this server (52), and at least one of them is a non-binary sort order. Backup or restore operation terminating abnormally."
Why i got this error message? And what is "backed up under a diffrent sort order ID (54)" ?

I have a full database backup in a .bak file which includes both mdf and ldf parts. Unfortunatly when I try to restore the database the ldf it requires far more hard drive space than I have avaliable.
Is there any way to restore the database minus the log?
Or, is there any way to split the .bak file to the mdf and lfg files and restore just the mdf?
I cannot do another backup, or trim and backup. This .bak file is all I have to work with.
Thanks in advance!

If a SQL 2000 server instance is destroyed, but the database file (*.mdf) is saved on the disk, can a database within a newly created server instance be built on the saved file?
If I attempt to create a new database and choose the saved mdf file as the data file, then the server refuses to accept this file. Is there a way to create the new database and make it read the standalone mdf file?
Please help if at all possible. Thanks.
