The 3-2-1 backup rule is a proven strategy for protecting your audio projects and files from loss or corruption. It recommends keeping three total copies of your data, stored on two different types of media, with one copy kept offsite. This approach ensures that your work remains safe from hardware failures, accidental deletions, or disasters. Following the 3-2-1 rule gives Adobe Audition users peace of mind knowing their recordings and sessions are always recoverable.
