Ahora, los combinamos un poco para ajustarlo a nuestro gusto…
RAR.EXE m -agYYYYMMDDHHMMSS -m5 -r -y -dh -k -ep1 -s -md4096 -to365d
C:\carpetadedestino\bk.rar "C:\carpetaconarchivos\*.*"
Listo, ya tenemos todos los archivos anteriores a 365 días en el BK.RAR. El único detalle es que el compresor no borra las carpetas… pero nada serio, tenemos la nota anterior que nos muestra cómo hacerlo automáticamente.
Otra cosa para destacar del parámetro –TO es que soporta días, horas, minutos y segundos. El formato para solicitarlo es:
[d][h][m][s]
Por ejemplo se prodria usar: -to15d para afectar a archivos anteriores a 15 dias o bien –to2h30m para hacerlo con archivos anteriores a 2 horas 30 minutos.
