Fetching Older Repository Snapshots
In addition to all of the previous commands, you can use svn update and
svn checkout with the
--revision option to take an entire working copy “back in
time”:[7]
$ svn checkout -r 1729 # Checks out a new working copy at r1729 ... $ svn update -r 1729 # Updates an existing working copy to r1729 ...
Tip
Many Subversion newcomers attempt to use the preceding svn update example to “undo” committed changes, but this won’t work as you can’t commit changes that you obtain from backdating a working copy if the changed files have newer revisions. See Resurrecting Deleted Items for a description of how to “undo” a commit.
Lastly, if you’re building a release and wish to bundle up your
files from Subversion but don’t want those pesky .svn directories in the way, you can use
svn export to create a local copy of
all or part of your repository sans .svn directories. As with svn update and svn
checkout, you can also pass the --revision
option to svn export:
$ svn export http://svn.example.com/svn/repos1 # Exports latest revision ... $ svn export http://svn.example.com/svn/repos1 -r 1729 # Exports revision r1729 ...
