We expect the card to work for at least 10 years. LM is optimized to minimize the amount of writes, most frequently used files are stored or cached in RAM. You can make a full disk image to quickly restore it, but you will have to open the enclosure and remove the card from the device. Or you can use backup and a restore image, but then you won't have some configuration files like network config etc.
