The invention provides a log recording method comprising the steps of presetting at least two disks in the local and presetting at least one disk in a server; setting priorities of the disks; and writing log data into the disks according to the priorities. The invention also relates to a log recorder corresponding to the log recording method. The plurality of disks are preset, so that the log data can be written into the plurality of disks, and disk resources are reasonably distributed by setting the priorities of the disks and writing the log data according to the priorities of the disks, so that utilization efficiency of the resources is improved. The other disk can be selected for writing the data when the log data cannot be written into the certain disk, and thus the problem that in the prior art, the log data cannot be recorded due to operating environment and network faults is effectively solved.
