Realigas Kopioj de sekureco (Backups) Incrementales kaj autom?Ticas Pere de rsync, Uzas malmolajn ligojn por la kopioj incrementales kun kio la kopioj de sekureco okupas malmultan spacon en la disko.

B?Sicamente, La programo realigas unuan kopion kaj en postaj kopioj kopias la novajn kaj modifitajn arkivojn, Kreante Malmolaj ligoj Al la arkivoj kiuj jam exist?An. Aso? Kiu la pluaj kopioj nur okupas la novajn arkivojn.
