question about svnadmin load
How does load behave when revisions in the dumpfile already exist in
the repository? In other words if I ran the following commands:
svnadmin dump -r 0:2542 repo1 | svnadmin load repo2
svnadmin dump -r 2000:HEAD --incremental repo1 | svnadmin load repo2
The question is because I need to maintain repository mirror that must
be offline. I'm wondering if I can overlap dump files so that I don't
need to keep precise track of the previously synced revision. I
haven't seen this topic mentioned anywhere.

you can also look into using svnsync.

svk is based on svn, so you get all the svn features with svk. There
should be no difference in revision numbers, as I understand it. The
benefit in your case would be to have a local copy of the repository.
Another option would be to use svnsync to maintain a copy of the
primary repository.

If you load a dumpfile into a repository that is not empty, then the
revisions from the dumpfile will get added to the repository after
the revisions that are already there and revisions from your dump
will get renumbered as necessary.

Revisions 0 thru 2545 of repo1 will be loaded into repo2. If repo2
was empty, then repo2 will now have 2545 revisions.
> svnadmin dump -r 2000:HEAD --incremental repo1 | svnadmin load repo2
This will try to load revisions 2000 thru HEAD of repo1 into repo2
again. This will fail because the change made in revision 2000 in
repo1 already was made in repo2.

Then you should look at the tool svk.

You can't.
