How to back up data and develop tools for java web programmers

if the computer is poisoned and reinstalled, do all development tools have to be reinstalled? Is it useful to install it on D drive in advance? Is there anything you should pay attention to in the database data?

  1. set up a flag that has not been poisoned. Reinstall it if you reinstall it
  2. can you guarantee that disk D is safe if it is poisoned? If it is not poisoned, as long as disk D is not erased, some software can open
  3. after reinstallation.
  4. it would be nice to keep the table structure in the database. The development book should be full of test data. If it is gone, it will be gone. Or make regular backups.

eclipse can be installed in green
JDK is also
MAVEN is also
many others can
back up the environment variables
C disk is powerless, if you want to reinstall the


code, those can be transferred to Github or code cloud, or you can set up a server to build a private warehouse, and the rest of maven can be compressed. As for the development tools, you can package or directly copy the configuration of the workspace. Idea has its own export and import configuration file. In short, try not to put C disk in things and storage paths.
