I can supply you with one casual observation and one tip: I think I saw that warning when I changed from tar to rsync XferMethod. As you know, tar and rsync encode the file type "plain file" differently in attrib files (rsync has a bit for it, tar (like stat()) doesn't and simply takes the absense of a bit for a special file type to mean "plain file"). When rsync compares remote and local file type (remote from remote rsync instance, local from attrib file generated by tar XferMethod), it assumes a plain file changed its type, so it removes the local copy (if that sounds strange, remember that File::RsyncP mimics plain rsync, which *would* delete the local file; with BackupPC's storage backend, that doesn't make sense, hence the warning) and transfers the remote file without a local copy to compare to. Or something like that. If you want to know more, look at where the source code generates the warning message (well, that's stated *in* the warning message) and where that code is called from (presumably File::RsyncP) and in which circumstances. Good luck. Since you asked, don't forget to report back ;-).

Well I just upgraded and reinstalled Fedora on my Linux server and ran a new full backup. Again I noticed dozens of these type errors. All of them appear to be symbolic links but the links both in the new full and in the previous full appear to be intact. Also, this occurred on only about 40 out of many hundreds of symbolic links on my system. I am curious about what could be causing this situation that seems to be: 1. Limited to symlinks 2. Seems to only occur after a change to the system (presumably rsync is seeing the same link with a different inode) 3. Only occurs on some links.

[BackupPC-users] Unexpected call BackupPC::Xfer::RsyncFileIO->unlink(...)
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.

But for some reason BackupPC thinks that the existing file (ie: the one backed up in the previous full backup) is not a regular file. The file will be re-transferred. What happens when you browse the previous full backup and look at the file type of those three files?
