Partial Backup && Restore
May 8, 2008
Hi - I am using partial backup & restore on a Data Warehouse database currently in development.
When I recently tested the restore procedure I got the following error when trying to an online restore of one of the ReadOnly filegroups:
Msg 3125, Level 16, State 1, Line 1
The database is using the simple recovery model. The data in the backup it is not consistent with the current state of the database. Restoring more data is required before recovery is possible. Either restore a full file backup taken since the data was marked read-only, or restore the most recent base backup for the target data followed by a differential file backup.
I believe I received this message as the Filegroup I was attempting to restore had been set ReadWrite since it was backed up.
So - I am looking for a query to test that all my filegroup backups are consistent with the live database.
I think I can achieve this by checking the read_write_lsn & read_only_lsn values for the filegroup to restore are the same as the values in sys.master_files for the live database.
I am reading the lsn values for the backup from msdb.dbo.backupfile
Can anyone confirm this is the correct approach? or is there a better way to do this??
Many Thanks

Our current application which is deployed to numerous client sites usually requires the database to be returned to us to upgrade for the next release. The current process is:
- Perform a full backup at the client site
- Send the backup to us for upgrade
- Perform a full restore process to our local db server
- Modify the database
- Perform a full backup
- Send the backup to the client
- Perform a full restore over the original database.
This has served our purposes so far, however, we are about to introduce functionality that will enable the client to upload files for storing in the database.
To manage this we have a single DBFiles table which due to the potential size of it’s contents we determined that it would be best to store it in it’s own FileGroup. The idea being that then we could backup just the Primary FileGroup for returning to our offices as the DBFiles table would remain untouched.
The proposed process would now be:
- Perform a partial backup of the primary filegroup at the client site
- Perform a partial backup of the DBFiles filegroup at the client site. This only ever stays at the client site and is never restored at our office.
- Send the primary filegroup backup to our office for upgrade
- Perform a partial restore or the primary filegroup to our local db server. This will leave the DBFiles filegroup offline which is OK as we do not need to change it.
- Modify the database
- Perform a partial backup of the primary filegroup
- Send the partial backup to the client
- Perform a partial restore of the primary filegroup over the original database. This will leave the DBFiles filegroup offline.
- Perform a partial restore of the DBFiles filegroup over the original database.
This last step results in the recovery failing due to a reason like “The roll forward start point is now at log sequence number (LSN) 66787000000001800001. Additional roll forward past LSN 66787000000008900001 is required to complete the restore sequence�.
I have tried a number of variations including backing up both the client and local log files for recovery and using copy_only but I have yet to be able to successfully complete the process. Is there a means we can synchronize these 2 backup files without worrying about the logs for this part of the process?
Our requirements are basically to be able to perform a partial backup and exclude the DBFiles table as it is likely to be very large so we can send it back to our offices for upgrade and then return it to the client for restoring back to the original database while maintaining the data in the clients DBFiles filegroup and table.
Any guidance on what we need to change or a better process would be appreciated.

I am looking for a SQL Backup/Restore tools which can restore multiple environments. Here is high level requirements.
1. We have 4 DBs, range from 1 TB - 1.5 TB Each Database. When we restore to QA, DEV, or Staging, we usually restore 4 of them.
2. I am looking for the speed to complete restoring between 1 - 2 hours for 4 DBs.
I am evaluating the Dephix Software but the setup is very complex and its given us a lot of issues with Windows Authentions, and failure in the middle of the backup. I used Guess Software many years ago but can't find it on the web site any more. Speed is very important for us mean complete restoring as fast as possible. We are on SQL 2012 and SQL 2008 R2.We are currently using NETAPP Technology and I have Redgate Backup Tool but I am mainly looking for fast Restore Process.

I should restore a SQL Server 2005 Database from backup. The backup contains three files, named user.bak0, user.bak1 and user.bak2.
How is the syntax of the restore filelistonly and the restore database ... ?
I usualy write
restore filelistonly from disk = 'path and filenam.bak'
restore database. zy
from disk = 'path and filename.bak'
with replace,
move.....
move....
This works but I cannot use it with a splitted backup file. The files are much too big to put together to one file.
Thanks in advance for any help.

I neglected to backup the transaction log as part of the process of backing up the database. Now i only have the backup file for the database and no transaction log backup. When i try to do a restore on the database, i get the error on a "tail log missing" message (which i'm assuming is that it's looking for the t-log backup?).
Is it possible to restore or even restore to a new database? I'm only looking to retreive data from 2 tables within the backup file.
Thanks!

I had to replace my hard drive which was going bad. I reinstalled Sql 2005 and now need to restore the backup that I have. I selected Restore Database and chose From Device, and selected the backup location on J: drive and selected the backup file which has no extenstion. I checked the checkbox next to the backup set to restore. Click OK and then I get this error message:
Restore failed for Server
System.Data.SqlClient.SqlError: Directory lookup for the file "C:Program FilesMicrosoft SQL ServerMSSQLdataMyDB_Data.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.Smo)
I don't know why it is looking for a MDF file as this was never in the Backup folder. Can someone please help me on this? I thought I was doing the right thing making a backup all along and now I can't restore it!

Hi I am operating my databases under "trunc log on checkpoint" mode as I do not need point of failure recoverability.I was performing a recovery test using a backup which resulted in it being unsuccessful .Error Message received was
"Recovery has failed because a nonlogged operation could not be redone.Use the RESTORE statement to restore all data in filegroup PRIMARY to a pt beyond the nonlogged changes"
Isnt sql*server supposed to prevent a non-logged operation while a backup is in progress?Also how do i prevent such a situation from recurring.
If i switch to single user mode before a backup how do i prevent exisiting users from accessing ... without bouncing my sql*server?

Cannot open backup device 'NetworkDevice'. Device error or device off-line. See the SQL Server error log for more details.

Whenever I restore a backup on sqlserver 7.0 and create a new database from it, I always end up having problems with the users existing in the backup.
To enable those users to have access, I end up creating logins with those names and when I try granting those users Database access, I get the error message that the user already exists in the database.
Could some one tell me the right way to restore the backup and having all the users of the database also restored in the proper manner.

WE are using sqlserver 7.0 & backing full database using Seagate backup ver 7.2 on a tape drive.
I have following questions if anybody could help
1]How do I restore a single table backup from the tape backup without restoring the full database first on the disk & then running import/export
utility to transfer/ copy that particular table to production database.
Is there any third party backup utility which allows for a single / selected table restore?
2]What are the steps or if anybody has the script for tansfering logins/users
with permisssions & without deencrypting the passwords when transfering from one server to another server.

I have a question related to SQL 6.5. We have a SMS 1.2 server which uses SQL 6.5. Two months ago, one of the NT admins did a NT backup of SMS database(sms.db) and then formatted the HD. Now, we need the SMS server back again. We installed the NT server, SMS server snd SQL server on that machine. The problem is, we now want the SQL server to recognize our SMS database (SMS.db file). We don't have any SQL backup of any database (that means, no copy of master database, no copy of other databases. IS THERE A WAY TO RECOVER SO THAT SQL SERVER RECPGNIZE THE SMS DATABASE(SMS.DB FILE)

Hi All,
I've been working developing database on my PC @ work, and sadly enough would like to spend some time on it at home. To these ends I backed up the database at work where it restored fine. However have tried to restore the file at home and am getting an error saying the operating system cannot access the file. Is this something to do with NTFS permissions?
Thanks in advance

hi,
I want to know if there is a way - other than backup and restore database (because restore takes too much time as the DB size grows) - to transfer all the data from one database on the server to another on a local SQLServer. it has to be done daily, so that the manager will always have an updated copy of the data on his machine.
Any help?
Thanks in advance

I have been backing up my SQL Server 2005 databases for some time without needing to restore. Today, I attempted to restore a backup on another server and received the following message:
Restore failed for Server 'MGLENOVOSQLEXPRESS'. (Microsoft.SqlServer.Express.Smo)
System.Data.SqlClient.SqlError: The backup set holds a backup of a database other than the existing 'walls_Template' database. (Microsoft.SqlServer.Express.Smo)
HOWEVER, the name is in fact the same. BESIDES, what if I wanted to restore a copy of the database, shouldn't I be able to restore to a different name????

I am running SQL Server 2000 Standard Edition on a Windows XP Professional machine. Today the computer hung and when it came back up, the SQL Server Services will not start. There is not error message. If I try to start the service it starts but immediately stops.
I tried to rebuild the registry through the setup but that is not an option since the server components were not installed on my machine.
Is there a way to reinstall SQL Server without losing my data?
Thanks!

Hi, I'm from Argentina. I want to restore a database using Developer Ed. 2005 and I get the following error:
System.Data.SqlClient.SqlError: The tail of the log for the database "practicadb" has not been backed up. Use BACKUP LOG WITH NORECOVERY to backup the log if it contains work you do not want to lose. Use the WITH REPLACE or WITH STOPAT clause of the RESTORE statement to just overwrite the contents of the log. (Microsoft.SqlServer.Smo)
Any ideas? Thanks.
