I am trying to set up automated backups of my svn repositories with the help of backupninja, but it seems like the paths used when running the svn-hot-backup.py script are wrong. (svn-hot-backup.py is the copy-pasted hot-backup.py from here since I could not find it included in the raspbian dist)

This is the beginning of the log file:

This is my /etc/backup.d/action.svn file:

##
## Perform a hot backup of subversion repositories.
##
## REQUIRES: apt-get install subversion-tools
##
## This file can be empty, the defaults are usually good.
##

when = sunday at 02:00

## where subversion data lives
src = /mnt/data/svnrepos

## where to save the backups to
dest = /mnt/backup/data/svnrepos

## where to save temporary backups
## (if successful, $tmp is moved to $dest)
#tmp = /tmp/svn.tmp

## the hotbackup program to use.
HOTBACKUP = /usr/share/subversion/svn-hot-backup.py

## the name of the vserver containing svn, if using vservers
# vsname =

As you can see there is an extra ./ in the path to the repository. Is this a known bug or is something wrong in my configuration files?

I managed to find this script here /usr/share/backupninja/svn, but I have no idea if this it what creates the faulty paths:

# -*- mode: sh; sh-basic-offset: 3; indent-tabs-mode: nil; -*-
# vim: set filetype=sh sw=3 sts=3 expandtab autoindent:
#
# this handler will backup subversion repostitories.
#

getconf dest /var/backups/svn
getconf tmp /var/backups/svn.tmp
getconf HOTBACKUP "/usr/bin/svnadmin hotcopy"
getconf vsname

To fix it I added

repo='basename $repo'

right below the lines:

repo='dirname $repo'
repo='dirname $repo'

in /usr/share/backupninja/svn

I have also added a bug report to the official site
