Log2ram info

This service helps you extend your SD card’s potential life span by reducing the amount of data being written to it.

Your Raspberry Pi’s logs will now be written to the temporary disk located within the RAM. When you shut down, Log2RAM will save these files by synchronizing them back to the disk.

If you want to find the log files that are synchronized to your SD Card, you can find them at /var/hdd.log/.

Log2RAM will also synchronize these files daily if a restart or shutdown has not happened in the meantime.
