Unsupported File System Error When Trying To Upgrade iPhoto Library on QNAP

Question

I upgraded to iLife11 from iLife08. My iPhoto Library is stored on a QNAP server and has worked just fine for many years. When iPhoto[9] tries to upgrade the library it gives an error "The library could not be opened because the file system of the library's volume is unsupported."
Other iLife11 applications such as iMovie recognize files from the QNAP just fine.
I have tried moving the original iPhoto Library into another folder and then creating a new library on the server but get the same message.
I have upgraded to iPhoto 9.0.1 already.
Any ideas?
Appreciation In Advance.

Answer 1

my NAS backup is going to see the whole disk image as a 'new file' and
I don't think that will be the case if you use a sparse bundle disk image.
+A sparse bundle is essentially the same as a sparse disk image. The difference is that a sparse image is one giant file on your disk and a sparse bundle is lots of small files (8 megabytes each). They work and look the same way, but you can right-click on a sparse bundle, select "show package contents" and see the individual 8 meg sections.+
If the backup software can do incremental backups and work on packages I think it will work on the sparse bundle disk image. Might be worth a try.
