Being relatively novice to SVN, I needed to backup a recent installation. I found a couple of great scripts that was described for Linux, however, will work for Windows with additional software that is described in this article.
Dump the repository to a file.
svnadmin dump d:\csvn\data\repositories\myrepository > reponame.svn_dump
Or dump the repository to a compressed file. This requires gzip for Windows.
svnadmin dump d:\csvn\data\repositories\myrepository | gzip > reponame.svn_dump.gz
Or dump the repository to a compressed file. This requires 7-zip for Windows.
svnadmin dump C:\csvn\data\repositories\myrepository | "%ProgramFiles%-Zipz.exe" a -si backup.7z
Alternately, instead of dump, use svnadmin hotcopy REPOS_PATH NEW_REPOS_PATH
svnadmin hotcopy /repos \\backupserver\svncopy
To decompress the dump.
gzip -d reponame.svn_dump.gz
To import or restore your dump file.
svnadmin load d:\csvn\data\repositories\myrepository > reponame.svn_dump
