svnsync initialize — Initialize a mirror repository for synchronization from the source repository.


svnsync initialize MIRROR_URL SOURCE_URL


svnsync initialize verifies that a repository meets the requirements of a new mirror repository—that it has no previous existing version history and that it allows revision property modifications—and records the initial administrative information that associates the mirror repository with the source repository. This is the first svnsync operation you run on a would-be mirror repository.

Fail to initialize a mirror repository due to inability to modify revision properties:

$ svnsync initialize file:///var/svn/repos-mirror
svnsync: Repository has not been enabled to accept revision propchanges;
ask the administrator to create a pre-revprop-change hook

Initialize a repository as a mirror, having already created a pre-revprop-change hook that permits all revision property changes:

$ svnsync initialize file:///var/svn/repos-mirror
Copied properties for revision 0.
