here's a shell script I cooked up.

It assumes the repo is stored in /Volumes/Repodisk/svnowner/svnroot  
and hotcopies it to a new directory called /Volumes/Repodisk/svnowner/ 
svnroot_backup/$DATE.  It then tar-gzs the backup.  Finally, it scps  
it to another machine on the network.  Works fine on Mac OS X.   
You'll need to make sure your ssh-agent is running.

#!/bin/bash

BASE=/Volumes/Repodisk/svnowner
DATE=`date +%Y%m%d%H%M%S`
SVNROOT=$BASE/svnroot
SVNBKUP=$BASE/svnroot_backup/$DATE
ZIPPED=$BASE/svnroot_backup/$DATE.tar.gz
SCPDEST="svnowner@slug:~/svnroot_backups/"
echo $SCPDEST

echo "Starting svnadmin hotcopy:"
svnadmin hotcopy $SVNROOT $SVNBKUP
echo "Starting archive process:"
tar -cvzf $ZIPPED $SVNBKUP
echo "Copying archive over network:"
scp $ZIPPED $SCPDEST
echo "Done!"

Re: => Backup ?

[Jan Erik Moström <li...@mostrom.pp.se>]

Being a complete svn newbie and having only some personal repositories I created
a simple post-commit script that sets a flag, once each day another scripts
checks to see if the repository has changed, if so the repository is dumped to
folder. This and other folders are then backed up using dirvish.

Seem to work fine for my requirements.

Here's my solution (with dump, not hotcopy) - it is not perfect:
It reads the repos to dump from a file called "todump", This file
contains the repos in mention line-after line in the form of:
SVNROOT/repo1
SVNROOT/repo2
I have 2 scripts, one for incremental backups, one for full backups. If
the incremental script does not find a full backup, it does a full
backup.

svnbackup.incremental:

------8<----
#!/bin/sh
BACKUPDIR=/svn/backup/incremental/
SVNDIR=/usr/local/subversion-with-ssl-1.3.2/bin/
REPDIR=/svn/svn/
REP=`cat /root/bin/todump`
BZIP2="/usr/bin/bzip2 -9"

for i in ${REP} ; do
  if [ ! -d ${BACKUPDIR}${i} ] ; then
    mkdir -p ${BACKUPDIR}${i}
  fi
  CUR_REV=`${SVNDIR}svnlook youngest ${REPDIR}${i}`
  LAST_FULL_BACKUP=`ls -1 ${BACKUPDIR}../full/${i}/ | sort -n | tail -1`
  # If there is no full backup
  if [ x${LAST_FULL_BACKUP} == x ] ; then
    /root/bin/svnbackup.full ${i}
  else
    # actual version higher than last full backup?
    if [ ${CUR_REV} -gt ${LAST_FULL_BACKUP} ] ; then
      # something changed since the last incremental backup?
      LAST_INCREMENTAL_BACKUP=`ls -1 ${BACKUPDIR}${i}/ | sort -n | tail -1`
      if [ 0${LAST_INCREMENTAL_BACKUP} -ne  0${CUR_REV} ] ; then
        ${SVNDIR}svnadmin dump ${REPDIR}${i} --revision \
          ${LAST_FULL_BACKUP}:${CUR_REV} --incremental | ${BZIP2} > \
          ${BACKUPDIR}$i/${CUR_REV}
      fi
    fi
  fi
done
