[snip good testing]

So I believe you are mistaken about your backups being 90% larger, unless it it simply from the fact that your files are very small and there are a very large number of inodes.


Does a link count change on the inode trigger a "file change" event as far as Networker is concerned? That is, will a simple link count change (adding a new hard link) on an otherwise unchanged and already backed-up file cause it to be backed up again on the next incremental?

I've never tried it, but that seems like a possibility, and could explain the increased backup size.

I would say that is almost certainly the case, and probably the cause of the problem.
