Mirror pushing copies all refs - branches, tags, and notes - from one repository to another, keeping them in perfect sync. As the creator of CoreUI with over 25 years of version control experience since 2000, I’ve used mirror pushes for backup strategies, repository migrations, and maintaining read-only mirrors for different teams. The standard approach adds a secondary remote and pushes with --mirror to replicate everything exactly. This ensures the destination is an exact copy of the source.

Mirroring Git repositories creates exact copies including all branches, tags, and refs for backup, migration, or multi-location synchronization. With over 25 years of software development experience and as the creator of CoreUI, I’ve mirrored numerous repositories for disaster recovery and platform migrations. Git mirror cloning copies complete repository history and references, maintaining an exact replica that can be kept synchronized. This approach ensures complete backup coverage and enables seamless repository migration between hosting platforms.
