Removing unwanted data/release !!
Hi,
I have multiple repositories setup on my SVN server. As large number of commits are made the repository size keeps increasing regularly. Is there a way I can get rid of all unwanted revisions i.e. for example my current repo version is 4500 and I would want to keep only last 100 revision and delete all other. Is it possible and if yes then how ?
Regards
Himanshu Raina

Yes, you should use a new UUID on the new repository because it does
not have the same contents as the old repository. However, this means
that you cannot "svn switch --relocate", which is only for the case
when a repository has moved to a different URL but is otherwise the
same repository.

Yes, you can. You can use the 'svndumpfilter' to re-order and leave out the now empty revisions. However, this will confuse the *heck* out of checked out repositories, which will have newer revisions that are not in the repository. I've accidentally done this, and this way lies madness.
You would have to create a new repository with a new UUID, make very sure not to preserve the old UUID, and have people use the 'svn switch --relocate' command to switch to the new repository, even if you kept it at the old location. And if you're doing that, you may as well just have a new repository with a new name, so that your old legacy material is still available.

You can't do that without creating empty "dummy" revisions.
Ask yourself again if it's really necessary. What kind of growth are
you dealing with? Why are you putting these things in the repository
if you don't care about losing history?

Hi,
Dumping the repository and importing only unwanted data would change the revision number i.e say (of total 1000 revisions) if I dump revision 900-1000 from my existing repo and then create a new repo and load the dump file it would change the revision number from 1000 to 100 (i.e. 900-1000 would become 0-100). My requirement is to delete all older revisions and keep only the latest ones (assuming I don't need older revisions) without disturbing the revision numbering i.e. when I checkout or update my existing copy it shouldn't give me a conflict owing to changes made by me.
Thanks,
Himanshu Raina

The whole point of a system like Subversion is to preserve your
history. It's assumed that ALL revisions are wanted.
Unless you're changing many very large binary files, or doing your
moves & copies wrong, your repository should not be growing too
quickly. What kind of growth are we talking about here?
It is possible to remove revisions, but it requires taking the
repository offline, dumping the contents, then loading what you want
left in the repository (see
http://svnbook.red-bean.com/en/1.5/svn.reposadmin.maint.html#svn.reposadmin.maint.filtering
). And depending on your repository activity, doing so can actually
*increase* the size of your repository.

Unless you're changing many very large binary files, or doing your
moves & copies wrong, your repository should not be growing too
quickly. What kind of growth are we talking about here?
It is possible to remove revisions, but it requires taking the
repository offline, dumping the contents, then loading what you want
