SQL Server backup fails with network UNC share - sql

I am currently trying to take backup of a database to a network UNC share, but its giving me error.
I have two PCs connected in a simple NETWORK, not a domain.
From both pcs, I can easily create and edit files on either one.
One PC on which SQL SERVER is running and database files are located, is named SERVER.
Another PC on which I want to take backup, is named STUDENT-PC2. On this pc, drive d: is a shared drive and I set the full permission for this folder for Everyone, IUSER,NETWORK,NETWORK SERVICE
When I run following command from SQL SERVER MANAGEMENT STUDIO on SERVER, it throws me error as below.
I am running sql server service as NETWORK SERVICE
COMMAND
backup database dpmt to disk='\\STUDENT-PC2\d\DPMT_BACKUP_17032016_102719.Bak'
ERROR
Msg 3201, Level 16, State 1, Line 1
Cannot open backup device '\\STUDENT-PC2\d\DPMT_BACKUP_17032016_102719.Bak'. Operating system error 5(Access is denied.).
Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.

On computer "STUDENT-PC2" locate the file share that is destination for backups. In file share permissions add account named as your SQL machine plus dollar sign, like this: "SERVER$" - type that instead of username. Tick write+read permissions for that artificial "user", and hit OK to close. On the file system level configure permissions the same (write+read) or let Everyone write at first to test and then reduce.
In summary:
if both computers are not part of the same domain, the other computer (STUDENT-PC2) sees all local accounts from "SERVER" as "SERVER$" account, no matter what they real name is.
you need to set permissions on destination (STUDENT-PC2) for account "SERVER$" at two levels: file share permission level, and ntfs file system permission level.

SQL Server 2008 : error 5 - Invalid Parameter(s) found

I've been trying to figure out this issue for hours now.
I have 3 stations on the same network, all in which can talk to each other (I have folders shared on each computer that the others can access). The main station where the database is being held works with no problem. I can wrong the program and it can access the database, I can make changes etc.
Now when I attempt to connect the other stations to the master, I get an error:
Provider: Named pipes Provider, error. 5 - Invalid Parameter(s) found.
The following things are what I have done:
disabled firewall
shared SQL folder along with giving "everyone" full control
"everyone" has full access to the Data and Log folder
enabled the shared memory, named and TCP/IP pipes in Server Config Manager
I have a password for SA and I am using it to connect to the DB
DBConfigurator can connect to the DB from Station 2 (child) to Station 1 (master) with no issues but fails and ask for database settings when I open the program
Sorry if this is a little confusing but I don't know where else to go.

Complex sql query on BLK insert

I am using following query to load data from text file into database table
bulk insert Test_Training.dbo.test
from 'D:\SSRS\kasthuri.txt'
I have kasthuri.txt file in specified path. But I am getting error when I execute it.
Msg 4861, Level 16, State 1, Line 2
Cannot bulk load because the file "D:\SSRS\kasthuri.txt" could not be opened. Operating system error code 3(The system cannot find the path specified.).
The error message is because the service running your SQL server instance cannot access the file path. Wherever you place the file, you will need to open up the folder where the file resides to the MSSQLSERVER agent:
**I always struggle with this. For me, allowing MSSQLSERVER full permission to the folder where the input file resides always seems to work.*
Right-click the folder (as an admin on the box), go to properties, security, edit, add...
here is where I always get tripped up. For me, the server service account is "NT Service\MSSQLSERVER" and I can never search for that user. I have to type it in manually and check the name to make sure I typed it in correctly. For you, this may not be the service account used by your server. Check your services list from windows administrative tools to see what account is in "Log On As" for SQL Server (MSSQLSERVER).*

Restore a db backup file in sql server 2008 r2 through command prompt

I use this command to restore a database backup file in SQL Server 2008 R2 standard edition from the command prompt:
SqlCmd -E -S <local> -Q "RESTORE DATABASE [test] FROM DISK = 'C:dbbackup_14'"
Did you manage to get any closure on what this issue was? I have the same scenario where the backup has been running fine, however overnight it failed with the same error:
Msg 3201, Level 16, State 1, Line 1
Cannot open backup device 'E:\hg_backup_20100915.bak'. Operating system error 5(failed to retrieve text for this error. Reason: 15105).
Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.
My server is running on Network Service account and this has full permission to the specified drive. As above, backing up to another drive works, however I do not have enough capacity to simply change the path for all databases.
This is super weird given that nothing has changed at all since the last successful backup (which was the previous night).
Thanks,
Indra
At first blush it appears that you are missing the '\' in the path. Shouldn't it be 'C:\dbbackup_14'? If that's not it, it could be a space issue on the destination drive and keep in mind that if the database is (for example) 3GB in size, SQL Server is going want a bit more than that available to restore the database.
Hope this helps.

SQL Server Operating system error 5: "5(Access is denied.)"

I am starting to learn SQL and I have a book that provides a database to work on. These files below are in the directory but the problem is that when I run the query, it gives me this error:
Msg 5120, Level 16, State 101, Line 1 Unable to open the physical file
"C:\Murach\SQL Server 2008\Databases\AP.mdf". Operating system error
5: "5(Access is denied.)".
CREATE DATABASE AP
ON PRIMARY (FILENAME = 'C:\Murach\SQL Server 2008\Databases\AP.mdf')
LOG ON (FILENAME = 'C:\Murach\SQL Server 2008\Databases\AP_log.ldf')
FOR ATTACH
GO
In the book the author says it should work, but it is not working in my case. I searched but I do not know exactly what the problem is, so I posted this question.
SQL Server database engine service account must have permissions to read/write in the new folder.
Check out this
To fix, I did the following:
Added the Administrators Group to the file security permissions with
full control for the Data file (S:) and the Log File (T:).
Attached the database and it works fine.
An old post, but here is a step by step that worked for SQL Server 2014 running under windows 7:
Control Panel ->
System and Security ->
Administrative Tools ->
Services ->
Double Click SQL Server (SQLEXPRESS) -> right click, Properties
Select Log On Tab
Select "Local System Account" (the default was some obtuse Windows System account)
-> OK
right click, Stop
right click, Start
Voilá !
I think setting the logon account may have been an option in the installation, but if so it was not the default, and was easy to miss if you were not already aware of this issue.
To get around the access denied issue, I started SSMS as administrator and that allowed me to attach a database from my local drive. The database was created in another SQL and windows instance.
This is Windows related issue where SQL Server does not have the appropriate permission to the folder that contains .bak file and hence this error.
The easiest work around is to copy your .bak file to default SQL backup location which has all the necessary permissions. You do not need to fiddle with anything else. In SQL SERVER 2012, this location is
D:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup (SQL 2012)
C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup (SQL 2014)
C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\Backup (SQL 2016)
I had this problem. Just run SQL Server as administrator
Yes,It's right.The first you should find out your service account of sqlserver,you can see it in Task Manager when you press ctrl+alt+delete at the same time;Then,you must give the read/write privilege of "C:\Murach\SQL Server 2008\Databases" to the service account.
I solve this problem by adding Full control permission for both .mdf and .ldf files for Users group.
The problem is due to lack of permissions for SQL Server to access the mdf & ldf files. All these procedures will work :
you can directly change the MSSQLSERVER service startup user account, with the user account who have better privileges on the files. Then try to attach the database.
Or you can assign the user to the file in security tab of the mdf & ldf files properties with read and and write privileges checked.
Startup with windows administrator account, and open SQL Server with run as administrator option and try to login with windows authentication and now try to attach the database.
For me it was solved in the following way with SQL Server Management studio
-Log in as admin (I logged in as windows authentication)
-Attach the mdf file (right click Database | attach | Add )
-Log out as admin
-Log in as normal user
The actual server permissions will not matter at this point; all looks ok.
SQL Server itself needs folder permissions.
depending on your version, you can add SERVERNAME$MSSQLSERVER permissions to touch your folder. Othewise, it has to be in the default BACKUP directory (either where you installed it or default to c:\programfiles(x)\MSSQL\BACKUP.
Even if you do the following steps you COULD get the same error message.
1. login as SA user (SSMS)
2. Edit the file permissions to say "everyone" full access (windows folder)
3. Delete the Log file (Windows Exploring (this was what I had done per advise from some msdn forum)
I still GOT the permission error, but then I noticed that in the Attach screen, the bottom section STILL showed the LOG file, and the error message remained the same.
Hope this helps someone who did the same thing.
It means the SSMS login user does not have permission on the .mdf file. This is how it has worked for me:
I had opened the SSMS (Run as administrator) and login as an administrator user, database right-click attach, click add, select the .mdf file, click Ok. Done.
I had this issue when I try to backup a database.
System.Data.SqlClient.SqlError:
Cannot open backup device 'C:\x\x\xxx.bak'.
Operating system error 5 (Access is denied.). (Microsoft.SqlServer.Smo)
When I had this issue I thought that the user which I'm connecting to database don't have rights to access to the backup location. I gave full control to that user but nothing changed. This is because the service for SQL Server is running with another user.
At this point you may choose changing user of the service to local system account or add access rights for the current user of the service.
I choose the 2nd one.
After that change backup succeeded.
Very Simple Solution.
Login with System admin
copy your mdf and ldf files in "C:\Program Files (x86)\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA" Where all other data file recides.
Now attach from there it will work
I used Entity framework in my application and had this problem,I seted any permission in folders and windows services and not work,
after that I start my application as administrator (right click in exe file and select "run as admin") and that works fine.
If you get this error on an .MDF file in the APP_DATA folder (or where ever you put it) for a Visual Studio project, the way I did it was to simply copy permissions from the existing DATA folder here (I'm using SQL Express 2014 to support an older app):
C:\Program Files\Microsoft SQL Server\MSSQL12.SQLEXPRESS2014\MSSQL\DATA
(note: your actual install path my vary - especially if your instance name is different)
Double click on theDATA folder first as administrator to make sure you have access, then open the properties on the folder and mimic the same for the APP_DATA folder. In my case the missing user was MSSQL$SQLEXPRESS2014 (because I named the instance SQLEXPRESS2014 - yours may be different). That also happens to be the SQL Server service username.
For some reason, setting all the correct permissions did not help in my case. I had a file db.bak that I was not able to restore due to the 5(Access is denied.) error. The file was placed in the same folder as several other backup files and all the permissions were identical to other files. I was able to restore all the other files except this db.bak file. I even tried to change the SQL Server service log on user — still the same result. I've tried copying the file with no effect.
Then I attempted to just create an identical file by executing
type db.bak > db2.bak
instead of copying the file. And voila it worked! db2.bak restored successfully.
I suspect that some other problems with reading the backup file may be erroniously reported as 5(Access is denied.) by MS SQL.
In linux, I went to /var/opt/mssql/data/ folder and opened a terminal with sudo then, changed my *.mdf and *.ldf file permissions as below in which you replace yourDB with your Database file name and myUser to currently logged username:
chmod 755 yourDB.mdf
chown myUser yourDB.mdf
chmod 755 yourDB.ldf
chown myUser yourDB.ldf
After that, it was reconnected without any issue.
If the database you are trying to attach is compressed it may show error message.
First you have to decompress the file. For that go to properties of mdf/ldf file >> then "Advanced" >> Uncheck "Compress Contents to save disk space" >> Press "Apply".
After that give it a try.
Run SQL Server management studio as Administrator
Log in as Windows user
Remove log file if you have only MDF file (haven't log file)
With 3 items in the above checklist, you will remove almost problems related with attach database task.
If you're using Storage Gateway - SMB (S3)
Do this from the management studio
EXEC xp_cmdshell 'net use X: \100.155.16.6\mystoragegatewayfolder xxmysuperpassxx /user:sgw-445577\smbguest /persistent:yes /y'
EXEC XP_CMDSHELL 'Dir X:' (this should show you the Directory info, serial no etc)
Mount the drive (This PC - > Mount network drive, using the same info above)
Test run a backup job using scheduled backup, this will force to use the sql server agent and you can see where it's writing and whats the issue if any.

Cannot attach database SQL Server 2012 error 5

When I type this:
CREATE DATABASE AdventureWorks2012
ON (FILENAME = 'C:\Users\sohm\Desktop\Pohm\AdventureWorks2012_Data.mdf')
FOR ATTACH_REBUILD_LOG ;
I get this:
File activation failure. The physical file name
"C:\Users\sohm\Desktop\AdventureWorks2012_Data_log.ldf" may be incorrect.
Msg 5123, Level 16, State 1, Line 1
CREATE FILE encountered operating system error 5 (Access is denied.) while attempting to
open or create the physical file 'C:\adventuredb\AdventureWorks2012_Data_log.ldf'.
Msg 1813, Level 16, State 2, Line 1
Could not open new database 'AdventureWorks2012'. CREATE DATABASE is aborted.
I know it has to do with permissions. I have the administrator account. I have read a million posts but nothing has worked so far. Also when I try to change the folder containing the mdf file, to full control but it keeps reverting back to read-only.
You should run SSMS as an administrator.
Also it is possible that you might be running query as an 'sa' user(sql server authentication).
Try running the query with windows Authentication.
SHORT VERSION
For allowing MS SQL server 2012 to attach the database files you must grant full access to the mdf and ldf files to:
NT Service\MSSQLSERVER
Full Access
LONG VERSION
SQL Security has been updated a lot in 2012 handling of files.
http://technet.microsoft.com/en-us/library/ms189128.aspx
If you look at the existing attached databases and there security you will probably see that there only are 2 roles allowed with full access. MSSQLSERVER and Administrators, when attached SQL Removes all other roles from the files.
Trying to set the MSSQLSERVER from the fil security Permission will not work.
Looking at your services.msc overview you will in a default install see that NT Service\MSSQLSERVER also runs the SQL server servics.
The service account is not visible, the same issue as with IIS AppPools, a sub group has been created by the system and "hides" the accounts from auto discovery, probably to try and secure the accounts but in my view just obscures the setup.

Open the SQL Server Management Stdio in Administrator mode(Right click -> Select Run as Administrator. If it asks for User name and password enter your Administrator user name password). Then select Windows Authentication click ok, and now try to attache it will attache without any error.
This has nothing to do with YOUR account. SQL Server is trying to write to that folder under the context of the service account that is running SQL Server. You can see who this is by going to the Services applet and seeing who the instance runs as (probably NT AUTHORITY\SYSTEM or whatever). You can override that or you can place your MDF files in the data folder, which SQL Server already has inherent access to, instead of placing them in this other location on your C:\ drive.
Another way to solve this is to change all the SQL Server services to Local System Account instead of services. Start -> Run ->Services.msc -> Scroll down to SQL Server, you should see five services that start with SQL Server. Right-Click, Properties, Log On, change to Local System Account. Repeat for all the rest of the SQL Server Services and restart them all.
Try This
Go to the folder where you have stored mdf file.
Select file -> Right click -> click on mdf give full permissions to file for logged in user Security.
If still issue persist and it might me because of corrupted transaction logs, you may use tool SQL Database Recovery Tool Repairs to repair your corrupted mdf file.
Figured it out. I went to sql server configuration manager and right clicked SQL Server Service. Then I added my Windows Admin account to run the service and now it works.
