== Backing up a Repository ==

(This is a summary of a thread on the [[MailingLists|mailing list]] around 2007-08-11. backing up of a Mercurial [[Repository|repository]] can be done:

 * regular cloning - only if you check in regularly
   * you may use mq init -c to also allow backup of your local changes (see MqTutorial)
 * copy the filesystem
   * mpm: there is a "potential not serious race" when somebody is pushing at the same time to the repo
   * mpm: There will be a partial commit in progress during the backup. The repo will contain part of the commit and won't pass verify. Doing a pull of the last good revision will repair it.
   * mpm: if the filesystem is able to create snapshots (like zfs) there is no race. take a snapshot, then back it up

----

As noted on [[CreateBundleOfAllChanges]], a compressed version of a repository may be created by using {{{hg bundle}}}:

{{{
$ hg bundle --all project.hg
}}}

Of course, such a full bundle file ("project.hg" in our example) of a repository does not contain extra repo-files like "hgrc" (these would need to be backed-up separately).
