Hi all, The part about the -S option in the rsync man page says: -S, --sparse Try to handle sparse files efficiently so they take up less space on the destination. Conflicts with --inplace because it's not possible to overwrite data in a sparse fashion. NOTE: Don't use this option when the destination is a Solaris "tmpfs" filesystem. It doesn't seem to handle seeks over null regions correctly and ends up corrupt- ing the files. This may have been true for Solaris 2.5.1 and older, but is not for Solaris 2.6 or later (for the last 12 years). Solaris tmpfs does not implement sparse files, so if you use -S on a Solaris tmpfs system, the files won't be sparse. This note would be more accurate if it said: NOTE: This option has no effect if the destination is a Solaris "tmpfs" filesystem. The files won't be sparse. Thanks, -Justin
