Dieter,
V4 rsync, by default, uses --checksum for full backups, which means the
full-file digest of the existing file is sent to the client together with
the meta data, and the client checks if the digest and meta data are the
same. If so, then no file is transferred (it's skipped just like in an
incremental). So those files count towards the total file count, but not
the Existing Files count. If the meta data has changed, or the full-file
checksum is different, then the rsync algorithm is applied, transferring
the deltas. In that case the file counts towards either the Existing or
New count.
That's different to V3, the first step is skipped, and a full uses the
rsync algorithm to transfer (send deltas) for every file, so it always
counts towards either Existing or New.
Alexander recently reported some bugs with file statistics (the restore one
is definitely a bug), and I need to look into those.
