If you are really attached to your statistics/graphs1090 data, please make sure to back up your mapped drives regularly* + If you are using a Raspberry Pi or another type of computer with an SD card, you may already be aware that these SD cards have a limited number of write-cycles that will determine their lifespan. In other words - a common reason for SD card failure is excessive writes to it. By the nature of having to log lots of data the `graphs1090` functionality writes a lot to the SD card. To reduce the number of write cycles, there are a few parameters you can set.
