Backup your home directory which contains all the user application
configuration, and restore that on to a new card containing a fresh
install of the OS. Reinstall applications, and for any system config
files that you had to manually modify, such as those in /etc, take a
copy, but manually reapply the changes to the new OS.

For that type of use don't rely on the SD card, they will die after a
finite period of time. Get yourself a modestly sized (64GB or 120GB) SSD
and keep the OS and data on that, it will be far more reliable. Just use
a small SD card to hold the boot partition, you can find the
instructions on how to do this on many websites.
