This article deals with how to backup your Subversion data and move it to a new machine. For a detailed article on setting up Subversion, see [[Subversion Setup]].
 
 
 
== Instruction ==
 
svnadmin dump repo and scp to other machine
 
Do this for each repository you have.
 
svnadmin dump /path/to/reponame > /tmp/reponame.dump ; scp -rp /tmp/reponame.dump user@server.domain.com:/tmp/
 
 
 
On other machine install subversion
 
pacman -S subversion
 
 
 
Make sure you set svnserve in /etc/rc.conf
 
Edit the DAEMONS line so it starts on next boot.
 
DAEMONS=(syslog-ng hotplug !pcmcia network netfs crond sshd svnserve httpd)
 
 
 
Create the corresponding repositories. Do this for each repository you have.
 
svnadmin create /path/to/reponame
 
 
 
Load svn dump into new repo on new machine. Do this for each repository you have.
 
svnadmin load /path/to/reponame < /tmp/repo1.dump
 
 
 
Setting Permissions.. <b>CRUCIAL</b> This is the most common mistake when moving an svn repo.
 
Do this for each repository you have.
 
chown -R svn:svnusers /path/to/reponame ; chmod -R g+w /path/to/reponame/db/
 
 
 
Sample Permissions:
 
{{bc|bash-2.05b# ls -l | grep svn
 
drwxrwxr-x  7 svn  svnusers      512 Apr 27 15:06 reponame1
 
drwxrwxr-x  7 svn  svnusers      512 Apr 27 15:06 reponame2
 
drwxrwxr-x  7 svn  svnusers      512 Apr 27 15:06 reponame3
 
bash-2.05b# ls -l reponame1/ | egrep -i "db"
 
drwxrwsr-x  2 svn  svnusers  512 Apr 27 15:07 db
 
}}
 
 
Ok these repos should be all set and ready to rock.. however using svn+ssh:// will not work..
 
{{Note|we have to have a wrapper written for svnserve.. PLEASE FOLLOW CLOSELY HERE}}
 
 
 
check your ENV like:
 
{{bc| bash-2.05b# env | egrep "^PATH="
 
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin:/root/bin
 
}}
 
 
 
check where the svnserve binary is located:
 
{{bc| # which svnserve
 
/usr/local/bin/svnserve
 
}}
 
 
 
ok our wrapper is going to have to fall in PATH prior to this location.. /sbin is a good place seeing its our 1st exec path on the system as root.
 
 
 
create wrapper:
 
touch /sbin/svnserve ; chmod 755 /sbin/svnserve
 
 
 
now edit it to look like so:
 
 
 
{{bc| bash-2.05b# cat /sbin/svnserve
 
#!/bin/sh
 
# wrapper script for svnserve
 
umask 007
 
/usr/local/bin/svnserve -r /path/to "$@"
 
}}
 
 
 
{{Note|See the -r /path/to ?? well this is what makes use of the svn co svn+ssh://server.domain.com:/reponame ( SEE THIS :/reponame ).. this sets root PATH.}}
 
You do not need to do: :/path/to/reponame.... this is the big trick here folks.
 
 
 
Start svnserve with new wrapper script like so:
 
/sbin/svnserve -d  ( start daemon mode )
 
 
 
check it with ps:
 
{{bc| # ps auxww | grep svn
 
root  66668  0.0  0.1  3608 1868  ??  Is  12:25AM  0:00.00 /usr/local/bin/svnserve -r /path/to -d
 
}}
 
 
 
we can also check the perms for remote users like this:
 
 
 
{{bc|cdowns:~ ~$ svn ls svn+ssh://server.domain.com:/reponame
 
++server.domain.com++
 
dev/
 
qa/
 
release/
 
cdowns:~ ~$
 
}}
