Back Up To A Logical Device And Restore It
Nov 6, 2007
I want to back up my database to a logical drive and restore it from this logical device. But I am unable to see my logical device through sql server management studio interface. I am able to back up to a logical device and restore it from logical device through T-SQL code. I am wondering how come I am unable to see my logical device from sql server management studio interface. Is there any way, I can solve this problem? Thanks in advance.

Is there any SYSTABLE or table from where I can get the backup device logical name.
Thanks,

What's is the between backing up a database to a file and a logical backup device?
If I point the logical backup device to a file on the filesystem, it's same as backing up to a file? isn't?
Thanks

Hello All,
I am facing problem with Logical File Name while restoring database. I am taking a backup of ABC database from Server1 in abc.bak file.
Then I am creating new database XYZ on Server2. Server1 and Server2 are not connected to each other in anyway, since both servers belong to different companies. Here on Server2 I want to restore backup of abc.bak on XYZ database. I select restore from Device, and on option tab I am selecting Force restore over existing database, in the below option I am specifying current Data & log file path for Move to physical file name.
But Logical file name shows ABC names, but if I tried to change those to XYZ names then restore fails. But if I keep ABC names then it works.
Is anybody knows how to over come this Logical Name issue?
Many thanks in advance….
Regards,
Santosh

This is my first attempt to use SQL Server Compact with Visual Studio 2005.
I wrote a program for Inventory Scaning which requires the database to be stored on an SD Card. As long as the device is left powered on, the programs function normally. However, if the device powers off and is then turned back on the 0xC0000005 error is displayed when the program attempts to do anything with the SQL Connection.
I have also written a small sample program to test and the results are repeatable each time.
The sample program consists of a single form with six buttons (Create Database, Open Database, Insert Records, Delete Records, Close Database, Dispose Database).
Both programs are written in VB.
Here is the code for the sample program.
Public Class frmSQLTest
Private cnDB As System.Data.SqlServerCe.SqlCeConnection
Private connString As String
Private Sub frmSQLTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.txtDB.Text = "Storage CardTest.sdf"
End Sub
Private Sub txtDB_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtDB.LostFocus
connString = "Data Source=" & Me.txtDB.Text
Me.txtStatus.Text = "Connection String Set"
End Sub
Private Sub btnCreate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreate.Click
If Me.txtDB.Text = Nothing Then
MessageBox.Show("Unable to Create Database")
Exit Sub
End If
Dim eng As New System.Data.SqlServerCe.SqlCeEngine(connString)
eng.CreateDatabase()
eng = Nothing
Me.txtStatus.Text = "Database Created"
End Sub
Private Sub btnOpenDB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpenDB.Click
Dim sqlDB As New System.Data.SqlServerCe.SqlCeCommand
If cnDB Is Nothing Then
cnDB = New System.Data.SqlServerCe.SqlCeConnection(connString)
End If
cnDB.Open()
Me.txtStatus.Text = "Database Opened"
sqlDB.Connection = cnDB
sqlDB.CommandText = "CREATE TABLE Master (Item nvarchar(12), Description nvarchar(19))"
sqlDB.ExecuteNonQuery()
sqlDB.CommandText = "CREATE INDEX idx_Master on Master (Item)"
sqlDB.ExecuteNonQuery()
Me.txtStatus.Text = "Master Table Created"
sqlDB = Nothing
End Sub
Private Sub btnInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnInsert.Click
Dim RecCount As Long
Dim sqlDB As New System.Data.SqlServerCe.SqlCeCommand
sqlDB.Connection = cnDB
For RecCount = 1 To Me.nudRecs.Value
sqlDB.CommandText = "INSERT INTO Master ([Item], [Description]) " _
& "VALUES ('" & RecCount.ToString & "','Test Item " & RecCount.ToString & "')"
sqlDB.ExecuteNonQuery()
If RecCount Mod 100 = 0 Then
Me.txtStatus.Text = "Updating Record..." & RecCount.ToString
End If
Next
Me.txtStatus.Text = "Records Inserted"
sqlDB = Nothing
End Sub
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Dim sqlDB As New System.Data.SqlServerCe.SqlCeCommand
sqlDB.Connection = cnDB
sqlDB.CommandText = "Delete FROM Master"
Me.txtStatus.Text = "Master Table Cleared"
sqlDB = Nothing
End Sub
Private Sub btnCloseDB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCloseDB.Click
cnDB.Close()
Me.txtStatus.Text = "Database Closed"
End Sub
Private Sub btnDispose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDispose.Click
cnDB = Nothing
System.IO.File.Delete(Me.txtDB.Text)
Me.txtStatus.Text = "Database Diposed"
End Sub
End Class
In my tests, I start the program (loaded on the Storage Card in the same directory as the database). SQL Server Compact is also installed on the SD Card to save space in Main Memory.
Steps to Re-Create the Error:
1. Click the Create Database button. Database is created properly.
2. Click the Open Database button. Database connection opens properly.
3. Click the Insert Records button. Records are inserted into the table properly.
4. Turn off the Symbol MC3000 unit.
5. Turn the unit back on.
6. When I click on any of the following buttons, the error is displayed. Close Database, Insert Records, Delete Records.
I have also tried closing the database (as well as closing and disposing the database) prior to step 4 above, but when I try to re-open the database (or create the database) again, the error displays.
Is there anyway to correct this issue?
With the real program, the database must be kept open as long as each form is open to prevent speed issues and the database must be stored on the SD Card since there is not enough storage space available on the device.

Can two databases have same logical filenames in the same instance?
In my instance, database already exists say A.
I have to restore DB B with the same backup used for database A in the same instance.
So, once the database B is restored, A and B will have same logical fileNames.
Can I leave it as is? Or do i alter only after B is restored?
Or is there a way where I can change the logical file for B while restoring?

We tried to restore an empty database from a backup and got:
'Load database encountered an invalid logical page number' error.
This then set the database as 'loading'
Anyone got any ideas?
We aren't exactly sure how big the first database was when the backup was done but if the new database isn't big enough to contain the backed up data, wouldn't we get a more meaningful error?

Hi,
What I need to do is restore a full backup of one database to a database where disk space is limited.
so my source device is 2gb for data and 1gb for tranlog
my dest is 1.5gb for data and .5gb for tranlog
I am thinking this is not possible, but thought I would post here anyway!
Thanks in advance!

I want to be able to take a backup device to another server and then restore the last backup file within the device.
My script creates the backup device using the filename of the file from the other server but when I do the restore it only restores the first file in the device.
How can I get it to restore the last file? In EA I can do a manual resotre and look inside the device and choose say backup number 2.
How can I do this in a script?
Thanks

Hi All,
I have a problem that I haven't been able to solve it. At the end I am confused I need some clarifications.
Background:
I am using full back up recovery plan. I am getting daily full back up and every 15 minutes log_back up. I created these back ups by using Database Maintenance option. However I have been trying to restore the log_back up, but I couldn't achieve it.
Question1- When I take log back up do I have to activate "Remove inactive entries from transaction log" or not??
Info: When the log back up was done it deletes the latest 4th one. I have done this without no reason. Should I keep like that or should I allow the files being deleted right away after transaction logs backed up?
Question2- I cannot restore the log files I don't know why? I have followed every description that I read. After I restored full back up with NOREOCVERY the database hangs out says "loading" but it doesn't do anything and when I try to restore it doesn't accept the latest log back up file and it urges me to put newer file than I have but ıt is only latest log back up that I have Why does this happen?
I am so confused. Please help me
:confused:
Thanks
LS

I had to transfer my database from one server to another. Both are running SQL 2000. I backed the database up and moved it to the new server however when I try to do a restore I get the following message:
The media set for database "xxx' has 2 family members but only 1 are provided. RESTORE DATABASE is terminating abnormally.
I did some searching and found a couple of posts that mentioned something about the back up including 2 files.
My problem is that the machine I backed this up from crashed when it was shut down and would not reboot so all of the data and the original database do not exist. Is there any hope of restoring this database. It is pretty critical.
Thanks,
Melissa :-)

hi, I would like to know the correct reaction for a crash in both senarios.
First senario,
I made a full back up at 6 am , then scheduled sql server to make transaction log back up every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 12:30. How would I resotre the data in the first senario....Can I restore the full back up done at 6 am then restore the last transaction log backup ( which is 12 Noon ) . I am not sure If I need to resotre the whole tran from 6 am till the time it was crashed.
Second senario,
I made a full back up at 6 am, then scheduled sql server to make Incremental backup every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 3:00 pm. How would I resotre the data in the second senario. ....Do I restore the full backup at 6 am then restore each incremental backup backwords ( 2,12,10,8)
AS you can see, I am not sure how to deal with this issue, I do appreciate your feedback.
Best regards

I am maintaining a .net 1.0 asp.net web application that accesses a SQL server 2000 database. I need to backup the database and then restore it on a laptop. Currently it resides on a server. The problem is that on the server they are using sql server 2005. If I backup using 2005 and then try and restore this database using SQL server 2000 or 2005 on the laptop, I get an error message. "Too many backup devices specified for backup or restore; only 64 are allowed. RESTORE DATABASE is terminating abnormally.
What can I do to restore the database? Must it be backed up with SQL server 2000 and then restored with SQL Server 2005?
Please help!

Hello,
I have some C# (.NET 2.0) code that performs back-ups and also can perform restores of back-up files. I would like to validate the integrity of a file prior to initiating a restore operation. In other words, I want to know, before I try to restore, if the file is just a random file (picture, work doc, zipped backup, etc.) or if it is a valid SQL backup file.
Any help would be greatly appreciated.
Thanks,
hassiah

I have a database in development in SQL Server 6.5 that needs to be occasionally deleted and rebuilt from a script when table structures are changed. I found that when very complex queries were performed, the 2 MB default size of tempdb filled up and returned errors, so I went to the Enterprise Manager to expand tempdb, learned that I had to first expand a device to expand tempdb into, and foolishly chose to expand tempdb into the same device space used by my application, instead of into one of the system databases. Now when I try to delete the device in preparation for its rebuild, the Enterprise Manager responds with an error message saying the device can't be deleted because it contains system tables. Is there any way to get the expanded portion of tempdb out of my application device so that the device can be deleted, without reinstalling SQL Server?

I had a major disk failure, and the only SQL Server files I was able to recover were master.dat, msdb.dat,msdblog.dat, two text files and two database devices. My question, is it possible in SQL 6.5 to restore a database from just the database device, and if so, how? Thank you.

Basically I've been using Visual Studio 2005 for a few weeks now moving a Pocket PC project from 2003 to 2005. When I hit the Start Debugging Button every time until today the project would rebuild and deploy to my pocket PC allowing me to debug etc but now I get
The remote connection to the device has been lost.
Please verify the device conection and restart debugging.
I used to get this problem in VS2003 sometimes and just like the numerous posts on different sites that I've looked at the problem eventually goes away and I'm none the wiser. One guy said that he found that if he went to bed the problem was resolved when he came back!
My PDA running Windows 2003 2nd Edition is directly connected to my PC via a USB port. I've rebooted my PC and done a soft reset on the PDA but it didn't help. I'm using ActiveSync 4.1.
Does anyone know how to resolve this problem?
