Restoring backup from an enterprise edition to express edition

Is there really a known issue when restoring a backup file from an enterprise edition of SQL 2005 to express edition?

I'm getting this error:

Msg 3201, Level 16, State 2, Line 1
Cannot open backup device 'E:\MyBackup.bak'. Operating system error 2(The system cannot find the file specified.).
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

I tried running this too:
RESTORE FILELISTONLY    
FROM DISK = 'E:\MyBackup.bak'

same error:
The media family on device 'E:\MyBackup.bakk' is incorrectly formed. SQL Server cannot process this media family.
Msg 3013, Level 16, State 1, Line 1
RESTORE FILELIST is terminating abnormally.



My backup is fine and restorable (tried restoring to a SQL 2005 enterprise version on a different machine)

Any insights? Thanks!

The software does not detect a valid backup, you could mount that backup in an Enterprise edition and export data in a different way, like sql files, then inject them in your Express edition.. if this fails it will show wich operation is invalid on the reduced version

What happens when trying to inject the SQL?

If you see, something like "Error executing SQL at line XXX" or something its an indication that the database design is not compatible with the reduced function set of the Express edition, in that case you will need to de-desing the database and build up a conversion tool

Based on this
[My backup is fine and restorable (tried restoring to a SQL 2005 enterprise version on a different machine)]

I guess that it could be a service pack issue.
Any Sql Server should be able to restore a database backed up from the same level and service packs (2005-2005, 2008-2008) regardless of edition.

Can you check and compare service pack levels?

it's the same error. what I did for testing was create a database with one simple table in enterprise edition, insert one row, backup the DB and restore it to an express edition. it really will not work....

Cyberkiwi: i agree, that's why i suggested a plain text sql file transmission, the language should be compatible as the standard doesnt change from SP to SP, and should be backwards compatible if restoring into a 2008.

Faiga: in your last post you mentioned a DB backup-restore process, have you tested the sql method?
