Smbclient incrementals are based only on the mtime.  So a deleted
file, or a file modification that doesn't change the mtime (including
renaming a file or unpacking files from a zip archive) will not be
detected during an incremental.

Rsync, in contrast, detects deleted files, new files, or any
attribute change (eg: size, exist/delete, owner, modes, mtime)
during an incremental.

Long term I want to look into using the FileSys::SmbClient module
instead of smbclient.  This would give BackupPC direct access to
the client files and directories, allowing it to compare all the
attributes and file delete/create against the last full, which
would give more accurate incrementals.
