OTOS is a utility for automatic synchronization of databases by e-mail or file transfer.
See also Transfer modes.
OTOS has two parts:
OTOS generally requires no user intervention is set up properly.
The program starts, performs the synchronization, and closes when
finished. An activity log is saved for later review.
This kind of online synchronization is very cost efficient, even for
dial-up connections because only local ISP rates apply, although the
synchronization may involve several countries.
