1. A method for minimizing fan noise during a data backup, the method comprising:
initiating, at a computing device, a data backup at a first backup rate, wherein the computing device comprises a fan that regulates an internal temperature of the computing device;
iteratively adjusting a backup rate of the data backup until a noise level of the fan meets a threshold noise level, by:
calculating the noise level of the fan by:
determining a rotational speed of the fan; and
estimating the noise level based on the rotational speed of the fan, an age of the fan, and a type of the computing device;
comparing the noise level to a threshold noise level;
in response to determining that the noise level exceeds the threshold noise level based on the comparison, reducing the backup rate of the data backup by a first amount;
in response to determining that the noise level is less than the threshold noise level, increasing the backup rate by the first amount; and
performing the data backup at the adjusted backup rate.
