http://seaside.gemstone.com/ss/ScanBackup

scanBackupAtServerPath: '/opt/gemstone/product/seaside/data/backups/extent0.dbf'

determineFileTypeAndVersion is not implemented

In ScanTool it is a subclassResponsibility

The work on scanning transaction logs (starting with version 9) seems to  
have broken the ability to scan backups. If you revert to version 8 then  
the backup scanning should work. Of course, I'll work on getting both  
working in the latest version. Thanks for reporting this. --James

With version 8, readRecord raises an error. newClass is nil: unknown record  
type

In your example you state that you are scanning 'extent0.dbf'. Is this an  
extent (as suggested by the file name) or a backup (as suggested by the  
directory)? If it is an extent, then the error "unknown record type" would  
be correct because we do not scan extents, only backups (and transaction  
logs?). If it is in fact a backup, then I might need to see it. How big is  
it? Would you be comfortable making it available for analysis? If so, let  
me know where I can download it or let me know if you need me to provide an  
FTP site for you to send it. -- James

My first try was with extents. Then I realized I should do a full backup  
instead.
The last error was with:

SystemRepository  
fullBackupTo: '/opt/gemstone/product/seaside/data/backups/fullbackup'.
ScanBackup64  
scanBackupAtServerPath: '/opt/gemstone/product/seaside/data/backups/fullbackup'.
