Description: local and remote filesystem snapshot utility
 rsnapshot is an rsync-based filesystem snapshot utility. It can take
 incremental backups of local and remote filesystems for any number of
 machines. rsnapshot makes extensive use of hard links, so disk space is
 only used when absolutely necessary.

Description-pt_BR: programa para cópia rápida de arquivos remotos (como o rcp)
 rsync é um programa que permite que arquivos sejam copiados para e de
 máquinas remotas do mesmo modo que o rcp. Ele tem muito mais opções que o
 rcp, e usa o protocolo de atualização remota rsync para aumentar a
 velocidade das transferências de arquivo quando o arquivo no destino já existe.
 .
 O protocolo de atualização remota permite ao rsync transferir apenas as
 diferenças entre dois conjuntos de arquivos através de um enlace de rede.
 .
 Este pacote também inclui a funcionalidade do daemon rsyncd.
