Hi Experts.

I rebuilt my SBS2k8 box last week, dutifully backed up everything and used Sharepoint Designer 2007 to back up my small but precious companyweb site.  When I've come to restore it I fell over on the 25Mb bug in SP (all by 1.5Mb) Can somebody please tell me if it is possible to extract the files from the backup file?

Many thanks

Jon

A .cmp file can be renamed to a .cab file, and then simply extracted to a folder.

Thanks Jamie, that worked a treat.

Next problem is the extracted files the manifest.xml and any other non .dat files are missing from the .cab file, there are only .dat files there.  Any ideas if I can recreate them or extract the .dat's on their own?

TIA

I'd have thought they'd be in there. Might be worth doing a rename on some of your .dat files (a copy!) and see if they contain the manifest information or even are the file but with a different name.

Hi, I've checked all of the backup files from the past and none of them contain anything but .dat files unfortunatly, all numbered sequentially, starting with 0000000.dat 517 of them.

At the end of the day I see the options as;

1. Finding a workaround to the 25k bug.

2. Hand editing the .dat files to remove 1.5Mb of content in a way that leaves them internally consistent and then put back in a cab/cmp file and try again.

All your content got serialized to these dat files. Looking at them does option 2 seem at all realistic?
