Unexpected call 
BackupPC::Xfer::RsyncFileIO->unlink(cygwin/usr/share/man/man3/addnwstr.3x.gz)

I encountered the above error in my backup logs - repeated hundreds of
time though all interestingly only on different files in my
C:\cygwin\usr\share\man\man3 directory.


Now for context, this was part of a full backup after I reinstalled
Windows on a laptop. I had been testing BackupPC before so I had
interrupted BackupPC early in the backup several times before (and I
believe the cygwin directory is placed early in the backup based on
alphabetical order). 

Also, after interrupting a very partial backup, I noticed that
BackupPC_link was running. So perhaps, this is 'undoing' a
BackupPC_link operation that ran on a partial backup?

In any case, I am curious to know what causes the error and what does
it mean?
Is it an error on my system (in which case maybe I should be looking
at my system) or is it an error in backuppc?


Note from the below quoted thread from 2005, Craig claims that the error is
benign, but doesn't explain how/why.


Thanks
