Version Control & Data Backup

Version Control

• A version control system records the changes made to a file or set of files over time so that you can revert to specific versions later
• Git is a decentralized version control system meaning that it can run on your local machine offline
• Resources to get started using Git:
  • Data School’s Git and GitHub Videos for Beginners
  • GitHub Resources to Learn Git (including the Git Cheat Sheet)
  • Git the Simple Guide by Roger Dudler
  • Git Installation Instructions by Kate Bronstad

Data Backup

• Backup your data regularly
• 3-2-1 rule: Three copies of your data, on two different types of storage media, in more than one location.
• Check your backups for
  • presence/absence of files
  • matching file size 
  • accessibility (can you open the file?)
• Backup recommendations from Reed
