Backing Up The Sql Database(*.bak) And Restoring The Database In VB.net
May 25, 2006
Hi There,
I want to know how to backup and restore database from VB.net. ie I am trying to put two buttons on my form, Backup and Restore. When I click on Backup a Backup of the SQL Database with extension of *.bak is created. Similarly when I click on restore and select a database with *.bak extension it should restore that database. I saw a software where it created a backup of Sql database with extension of .zip containing the bak file which is password protected. when u restore the database it automatically gets unzipped and the database is restored. Can anyone help me.
Thanks in advance.
Regards,
Amit

Hi, I am in a production database server. Data has been added and deleted via the web. So there is alot of traffice in and out of the database. How can I make a backup plan to make sure I am not lossing any input or deleted data . I am familiar with backing up a database in regular intervals, but I amnot sure if this is the best way in this senario.
How can I take advantage of the transaction log in restoring the database.
Thanks
Ahmed

Hi,
I have been using the backup feature of SQL Express for some time and I thought it would be good to test a restore in case the worst happend. I moved my bak files to a usb memory stick and copied them to a machine and installed SQL Express so its empty no database's etc. So I right click the databae folder and choose restore from device and point to the db's but I get errors restoring them. What am I doing wrong? Is their any guides that give steps to backup and restore database's ? Any help would be great - I can of course provide more information need be.
Thanks,
Adam.

I am trying to backup and restore a 20GB SQL database from a SQL Server 2012 to another SQL Server 2014, but I have come across the following issues:
1) The developers [against best practice] have stored multiple images in fields within the database as binary code.
This therefore exceeds the 65532 character limit in some fields, so even though the images do show [based upon the data saved within this field], I cannot find the data in the field beyond this 65532 limit, within SQL Server.
How can I export / locate this data after the 65532 character limit?
2) When I have attempted to restore the database I am getting this error message:
Restore of database 'zapkam' failed. (Microsoft.SqlServer.Management.RelationalEngineTa sks)
Additional information:
System.Data.SqlClient.SqlError: RESTORE detected an error on page (1:1592996) in database "zapkam" as read from the backup set. (Microsoft.SqlServer.SmoExtended)
I have managed to restore two other smaller databases using the same technique, but am wondering if it's an issue with the database itself.
3) I have uploaded this database to the new server using FileZilla FTP Client, but it has cut out, painfully at 80% + 90% on a couple of occasions.
Is there a better solution for uploading these big files that I could possibly use? For example, uploading table by table or similar...

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

I want to restore a database (from an encrypted .bak file) - but *not* over the live original if you take my meaning. Encryption is the standard AES-256 that comes with Sql Server 2014 btw. I don't want the original touched/altered in any way. I would like to capture a success message if possible.I can extract the physical device name of the database in question using the following code:
SELECT physical_device_name, *
FROM msdb.dbo.backupmediafamily
WHERE media_set_id =(SELECT TOP 1 media_set_id
FROM msdb.dbo.backupset
WHERE database_name='MyDatabase'
AND type='D'
ORDER BY backup_start_date DESC)
I would like if the newly restored database was rename to something different than 'MyDatabase' (as shown above) and has different logs than the original. If possible, and capture a success message when restored.

What is the best way (short of backing up the entire DB) to make a copy of a Table so that It can be easily restored. We have a table that we want to make some serious changes to, but I want to make sure I can restore if if I need to (if the changes don't work)

From Help
Transactional replication includes the sync with backup option, which can be set on the distribution database and the publication database:
It is recommended to set this option on the distribution database in all cases.
Setting this option on the distribution database ensures that transactions in the log of the publication database will not be truncated until they have been backed up at the distribution database. The distribution database can be restored to the last backup, and any missing transactions are delivered from the publication database to the distribution database; replication continues unaffected.
Does database will not be truncated until they have been backed up at the distribution database mean that the database itself needs to be backed up OR the log file with it?

I did a full backup of a db from one server(Express2005) and trying to restore it to a different instance of SQL2005 on the same development machine. (Also had some fulltext columns if that means anything)
Many failures but finally got it to report all was successful except the icon in Object Explorer shows (Restoring...) with no indication of any real activity going on. It's a tiny database with hardly any data in it.
Just not sure what the heck is going on there. It also won't let me into the database until this the (Restoring...) goes away.
Any advice on how to get this thing finished out?

When backing up a database in MS SQL 7.0, there is a window that appears in the destination section of the backup window. In this window is where the filename appears that the backup will proceed to and to the right of this window are "add", "remove" and "contents" buttons.
If there are multiple names in this window, will the entire backup go to both files or does it split the backup between the two filenames.

I have a Subscriber database updated using transactional
replication and want to create a copy for development & testing. The Distribution database is running on the
same 2005 instance as the Subscriber and the Publication database on another
server running SQL Server 2005.
If I use a TSQL script to run the restore, the database is
restored to a usable state but I get the following messages:
Msg 15247, Level 16, State 1, Procedure
sp_MSrepl_check_job_access, Line 112
User does not have permission to perform this action.
The replication agent job [job name] was not removed because
it has a non-standard name; manually remove the job when it is no longer in use.
(I€™ve removed the job name from the message)
RESTORE DATABASE successfully processed 46219 pages in
935.413 seconds (0.404 MB/sec).
It looks like an attempt is being made to restore
replication information too. I note that
the RESTORE statement has a KEEP_REPLICATION options which implies (I would have
thought) that by default the replication information is not be restored.
Incidentally, before implementing replication, backing up
the live database and restoring the backup to a new database took < 7
minutes but running the same process with a Subscriber database backup takes
about 15 minutes.
I€™d be interested to know if anyone has any idea what I€™m
overlooking or doing wrong.
ThanksTim

My client is changing hosting providers. We are trying to download a full backup of our MS SQL 2000 database from the old host. We can get all of the data using the Data transfer wizard in Enterprise manager. We can get all data and structure using the Data Transfer wizard with other options. However, when we do this, all of our tables get renamed with a prefix that is our username from the old host.
So, if we have a table named customers and our MSSQL login on the old host is userA, then our table gets renamed to tableA.customers.
This won't work with our applications and stored procedures. Changing tens of thousands of lines of code is not acceptable.
Does anyone know a way we can get a full copy of the database (rules, data, structure, keys, identies, etc) without having the username prefix?
Thanks for the help!

Hello,
I found some code below that works fine when I run it in my vb.net code in Design mode. When I publish the application, run the app and then execute the sub MyDbBackup() I get the following error: Cannot open backup device 'C:dbBackup'. Operating system error 5(Access is denied). BACKUP DATABASE is terminating abnormally.
Here is the code that runs:
Public Sub MyDbBackup()
Dim sqlconn As New SqlClient.SqlConnection(MyConnectionStringdb)
sqlconn.Open()
Dim Backupcommand As SqlClient.SqlCommand = New SqlClient.SqlCommand("BACKUP DATABASE [" & sqlconn.Database.ToString & "] TO DISK = 'c:myDataBaseBackup.bak'")
Backupcommand.CommandType = CommandType.Text
Backupcommand.Connection = sqlconn
Backupcommand.ExecuteNonQuery()
sqlconn.Close()
End Sub
2 Questions: Why does it backup fine in design mode, but not after it is published? Also, in design mode, my database is called TAP_Master.mdf but when I look under C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData, I do not see that database name... all I see is master.mdf, model, msdbdata etc... Is that database stored anywhere else?
I have set the MyConnectionStringdb variable to = "Data Source =.SQLEXPRESS;AttachDbFilename=|DataDirectory|TAP_Master.mdf;Integrated Security=True;User Instance=True"
Thanks in advance.

with the following being the default C:Program FilesMicrosoft SQL ServerMSSQL10_50.CMS_PROJECTMSSQLBackup
i name the file and it executes properly but when i try to restore that file to my local db that path is not even visible to me.In fact when i use exploreer I cannot even find the folders after Microsoft SQL Server!I search for .bak but nothing.How can I see that folder construction in the sql browser but never in explorer -

Dear sir/madam,
I am from NTU, Singapore and we have a windows 2003 server edition installed on a DELL server and it also runs MS SQL server 2000 for a project of ours. We have installed a HP tape drive on the dell server and it works fine if ntbackup is used at the command prompt but then the SQL enterprise manager does not recognize the tape drive and backing up of our database is of high priority as it contains sensitive information. But the tape drive is installed properly as the device manager does not show any error and ntbackup also recognizes it. I cant seem to figure out why SQL server 2000 cannot recognize it. It would be very helpful if you could kindly guide me on this issue.
Thanking you
Regards

It may sound like crazy question, But just curious to know if any one tested this scenario.
I was restoring an existing database from a backup. While the restore is in progress, I found i was restoring with old back, then I canceled the operation.
Now Will it restore the partial data or it rolls back the entire transaction and brings back to original status or it will currupt the database??

Anyone know of a good "free" way to back up web files and SQL Server 2005 Express Database?
I was able to use Windows Server 2003 Backup utility to back up the folder where the Databases were stored, as well as the web files, with no errors.
But I have heard a lot of discussion that you can't just simply backup SQL Server data files?
I'm wondering how sound the backup I've created is...
Any suggestions?

I have an online SQL Server database provided by an ISP. I do not havepermission to create a backup device and I understand this is normalpractice.I am not using Enterprise Manager to administer the online database.I know I can back up the structure of the database using SQLscripts.My question is:How do I back up on my own machine the data contained in the onlinedatabase tables I have created? If I were using Enterprise Manager Icould do it by downloading tables using the DTS facility but how can Ido it without Enterprise Manager?Is there some work around which I have missed eg creating a csv fileof the data?Best wishes for 2005 to all those helpful people in this newsgroup!John Morgan

I am having a problem backing up my database and TLog files due to alack of local diskspace. The db file is about 30GB and the TLog isabout 20GB each on a different hard disk. Each disk doesn't haveenough available space to accomadate a backup. I also can't shrink thefiles because part of that procedure would require a backup.Question: Can I use a redirected drive for the backup media? Is therea way to trick SQL into allowing this? If the answer is no, doesanyone have a suggestion as to want I should do? I am in the processof requesting more disk space,but that could take a while.Thanks,

1) We have got the database dump (.bak) file in one machine and we need to restore this to another machine where the SQL server (version 7) is running. But in the restore option there is no way to choose any mapped or shared drives in remote machine. Any pointer to resolve this problem?
2) Can you set up a database if you have the .mdf and .ldf files?

I am running SQL 7 on two seperate NT4 servers, a production server and a standby server. Both servers are configured for Mixed Mode authentication. If I back up a database on the production server, do I also need to back up the master database and restore it. My reasoning behind this is that users' login details will be held in the sysxlogins tbl in the master, while their access rights will be held in the sysusers tbl in the database I am backing up and restoring. If I back up and restore a database without backing up and restoring the master db as well, will the connection between the system login and the database user be broken.
Any comments/suggestions would be appreciated.
