mirror of
https://gerrit.googlesource.com/git-repo
synced 2024-12-21 07:16:21 +00:00
e284ad1d1a
The mirror option downloads a complete forrest (as described by the manifest) and creates a replica of the remote repositories rather than a client working directory. This permits other clients to sync off the mirror site. A mirror can be positioned in a "DMZ", where the mirror executes "repo sync" to obtain changes from the external upstream and clients inside the protected zone operate off the mirror only, and therefore do not require direct git:// access to the external upstream repositories.
