Vim backup and Restoration

Vim backup and restoration vim is an editing artifact. It is very easy to use when it is configured as an IDE style, but the configuration process is troublesome. After the configuration is completed a few days ago, do you need to configure the redo system again, the answer is no. How can we restore the vim environment? My experiment environment: ubuntu10.04.2 step1: backup file: 1. folder :/. vim 2. configuration File:/etc/vimrc step2: sudo apt-get install exuberant-ctags step3: copy the file you just backed up to the corresponding directory and modify the permissions, simple brute-force 777 permission OK, restored successfully!
