DISCLAIMER :: I am not an expert scripting out DB backups by any means, but the code I've come up with (in part derived from an article here on SSC) "appears" to work, meaning I see files being backed up to a specified network location, however, I cannot seem to get them to successfully restore to a new database (therefore, as far as I'm concerned it's useless :crazy:)
Why I am attempting this: Our nightly production DB backups have grown quite large (about 300GB after being compressed by HyperBac) and it's taking approcximately 3-4 hours to complete nightly. I am hoping to segregate the PRIMARY filegroup and an alternate INDEX filegroup into seperate backups. In testing, this significantly speeds up the data backup time and size on disk.
When I run the script below, I get the following files outputed to the backup location:
SANDBOX_20120209_115559_4464406_PRIMARY.bak
SANDBOX_20120209_115559_4464406_Test1.bak
SANDBOX_20120209_115559_4464406_Test2.bak
SANDBOX_20120209_115602_7632589_NCIndexes.bak
I am using the GUI in SSMS to restore the files but am not able to get it working.
When I try:
1. Restore Files and Filegroups
2. Eg: [New database name] = ABC
3. Choosing "From Device", then specifiying the PRIMARY BAK file
4. Entering SANDBOX for the "File Logical Name"
- Successfully runs, restores the backup
But I still need the other 3 files, don't I?
When I try to include the other files by:
1. Restore Files and Filegroups
2. Database: ABC
3. Choosing "From Device", then specifiying the Test1.BAK file
4. Entering SANDBOX for the "File Logical Name"
I receive this error:
Restore failed for Server 'BM015Q1-6410'. (Microsoft.SqlServer.SmoExtended)
File 'SANDBOX' was not backed up in file 1 on device '\as2-backup1\sql_backups\BM015Q1-6410\SANDBOX_20120209_115559_4464406_Test1.bak'. The file cannot be restored from this backup set.
RESTORE DATABASE is terminating abnormally. (Microsoft SQL Server, Error: 3144)
If I change the "File Logical Name" to "ABC" I get a slightly different error:
Restore failed for Server 'BM015Q1-6410'. (Microsoft.SqlServer.SmoExtended)
Logical file 'ABC' is not part of database 'ABC'. Use RESTORE FILELISTONLY to list the logical file names.
RESTORE DATABASE is terminating abnormally. (Microsoft SQL Server, Error: 3234)
If I repeat steps 1-3 above then attempt to add in all the BAK files (so I have all 4 total in the backup sets list) I get a more bizarre error:
An exception occurred while executing a Transact-SQL statement or batch.
I get the same error above if I even attempt to click on the "Options" tab...
What am I doing wrong?
If I can get this working properly I will most likely opt to script out the non-clustered indexes nightly as well, instead of backing up the INDEX filegroup...but need to make certain that I can successfully restore additional files/filegroups first.

You are not selecting the right backup..

I think I've looked at the code for too long and can't see the obvious, can you please tell me where I am missing that?

I suggest you look at Ola Hallengren's databae maintenance solution. http://ola.hallengren.com/ It has won a number of awards, and is likely to be a lot more reliable than something you build yourself.

I am quite familiar with that solution, but don't believe it allows for what I am trying to do specifically
