We are getting error and we are aware that there should be 2 files but we are able to find the second file,how to search all files(2) so that we may restore DB.
View 4 RepliesHi, I'm from Argentina. I made a backup of my database from ServerA (SQL 2000) and trying to restore it to ServerB (SQL 2005) I'm getting the following error: "The media set has 2 media families but only 1 are provided".
Any ideas? Thanks.
Dear All,
I know the basic defiinition of these two options, but i am not very clear why would someone choose one over another,
currently I am using Append to Media option, and every day backup, I see my backup files growing in size.
can someone give me nice example about these two options,
Thanks,
We have jumped straight to 64 bit SQL 2005 with no 32 bit 2005 inbetween.
However this means the tools we have cannot be installed on windows XP/2000 32 bit.
Is there some way to get the 32 bit tools as it appears strange that 32 bit tools were not provided for remote access.
Cheers
Julian
currently if I want to restore 1 db to another i do
RESTORE DATABASE userr
FROM DISK = 'd:sqlbackupsuser.bak'
WITH MOVE 'user' TO 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAuserr.mdf',
MOVE 'user_log' TO 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAuserr_log.ldf',
REPLACE
now I am backing up my db to a media - How can I do the same restore above but from that media (I don't remember what I made the media point to -- how can I find this out)

View 2 Replies View RelatedDoes anyone out there work with databases created using sp_create_removable?
I am encountering a situation that is a difference between 6.5 and 7.0 handling of these types of databases. In 6.5, our product creates a removable database on a fixed hard drive. When the user is ready to move the database to a jazz or zip drive, we set the database readonly and remove the log file. No problems. We can use sp_dbinstall witout a log file and everything works just fine.
In 7.0 we do the same thing, however, when we attach the database via sp_attach_db (which replaced sp_dbinstall), SQL Server 7 creates a new log file.
Is there any way to make SQL Server NOT re-create this log file?

It was difficult to enter a subject that coveres what I want to ask and also the explanation isn't trivial.
The question is for SQL server 2000 (I can't upgrade so solutions should be feasable on 2000). If patch level is an issue it chouldn't be a problem to patch to the level needed if it isn't there already.
The database has in full logged recovery mode and its .mdf filel and .ldf files are on 2 seperate disk locations (lets name these M: for the .mdf files and L: for the .ldf files).
Now whenever I read something about media failure it's allways about a failure of M: and how you then can backup you latest log file and have an 'up to the time of distaster' recovery. And that works fine. I played around a bit by putting M: and L: on a test machine on USB sticks, so that I could simulate media failures.
When I yank L: and simulate a media failure of the .ldf files the problem starts. You can't handle that database anymore since it becomes suspect and making a backup is not possible anymore (neither dbf nor ldf backup)
What I was able to do to get as close as possible to the time of failure was this:
1. Detach the database
2. Move the current .mdf file to a different location
(3. here I do whatever is needed to get the physical system working again)
4. Restore the database from the last full backup
5. Change the database to simple recovery model (needed to perform step 8)
6. Detach the database
7. change the restored .mdf file with the one set asside in step 2
8. attach the database
9. return to full logged
I then have a (and thats the main question actually) seemingly working database again with more data in it then I would have when doing the recovery by restoring the last full backup and all transaction log backups. To emphasis this: if I would have a weekly full and daily transaction log backups, if could lose up to a day of data, with the outlined method I would have much more data.
Now I know that the data are firstly written to the .ldf files and then to the .mdf files whenever the server has time for it (at least that is how I understand it) and so I should get more data then doing it the 'traditional' way.
How correct is that assumption and if so: how consistent are the data in that 'recovered' .mdf file?

However, when i try and install from the 64 bit CD or DVD I get errors such as not a valid Win32 application, or when i tre random msi's guessing as to which is ssms I get "This installation package is not supported by this processor type. Contact yoru product vendor."
I run a Pent D 2.8 on 32 bit XP

Hi,
This is my first post. I am trying to install SQL express on my PC but it keeps on having this error:
"encountered an unexpected error in datastore. The action is setdialogs..."
I have searched far and wide for a solution to this problem. Some solutions worked for others, but none worked for me so far.
I don't have a previously installed sql version on my laptop. But just to check, I followed the steps in using msiinv.exe to detect any previously installed software. I am pretty sure that there was no sql server entry in the output file.
I have all the requirements, installed (.net framework 2.0,etc). I have all the latest Windows updates (except XP SP3).
My laptop is well above the minimum requirements for sql express ( Core 2 processor, 2 gigs ram, 7Gigs free space).
I have the Protected Storage service running (which I found out was required to install sql server).
I even followed the directions to fix Cryptograhical services.
I am runninng out of options here.
Thank you for your replies.

I am new to SQL 2005. I have setup and new maintanaince plan of making backup on to different paths but i encountered an error saying
Executing the query "BACKUP DATABASE [promis_05] TO DISK = N'E:\ERP Database\ERP Backup\Promis_05', DISK = N'\\backupsrv\ERP Backup\Promis_05' WITH NOFORMAT, INIT, NAME = N'promis_05_backup_20061111181236', SKIP, REWIND, NOUNLOAD, STATS = 10
" failed with the following error: "The volume on device 'E:\ERP Database\ERP Backup\Promis_05' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set.
BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
We did not know what to make of this.
1) Is it bcoz i am backing up the database on 2 locations same time.
2) What is BACKUP WITH FORMAT?
3) Why won't it let me add a new file that is not part of the 'family' ?
4) How does it get to be part of the family?
Thought and ideas are highly appreciated!

Hiya,
We were recently let down by our software supplier who have happily provided us with a single processor license for SQL Server 2005 before the weekend.. but haven't been able to provide any installation media.
I notice on the website that there is a trial edition of the Enterprise edition for download, that can be converted into a full installation by using a valid license key.
My question is.. would I be able to use that trial edition with my license key? Or are they fundamentally different?
If that isn't an option.. is there anywhere where I can obtain installation files for standard edition?
Thanks in advance,

FROM
Forums f FULL JOIN Topics t ON f.forumid=t.forumid

I have following problem. I would like to provide to my STP encrypted data and decrypt them inside it. To decrypt the data I'd like to use DecryptByKey. Encryption should be made on the Win32/.NET client.
Unfortunately I cannot find the way to make the data understable between the both worlds. First how to assign the same key on the both side? Do I get the same key from
Code Snippet
create symmetric key MyKey with
algorithm=triple_des,
key_source='abrakadabra'
encryption by password='aaa'
and from
Code Snippet
string Key = "abrakadabra";
byte[] bKey = Encoding.ASCII.GetBytes(Key);
byte[] salt = new byte[8];
RNGCryptoServiceProvider rnd = new RNGCryptoServiceProvider();
rnd.GetBytes(salt);
PasswordDeriveBytes pdb = new PasswordDeriveBytes(bKey, salt);
TripleDESCryptoServiceProvider prov = new TripleDESCryptoServiceProvider();
prov.GenerateIV();
prov.Key = pdb.CryptDeriveKey("TripleDES", "SHA1", 168, prov.IV);
???
I have read somewhere that create symmetric key calls CryptDeriveKey, but I'm not sure.
The next point is the format of the output data. I have noted, that the output from EncryptByKey is 16 bytes longer (after stripping key guid and fixed 0x01000000) than the one from Win32/.NET application. I assume, that it can lie in the inserting of IV as the first block, but should not IV be only 64 bit long in the DES family of algorithms?
Neverthless I have not magaged to perform encrypted communication such way between SQL Server 2005 and client application. Is it possible at all?
