Subversion backup and restore

• Howto backup Subversion and move it to a new machine.
• Back Up Your Data !

• 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 -Sy 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 corrisponding repositories.
• Do this for each repository you have.

• 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.. CRUCIAL
• This is the most common mistake when moving a 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:

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 bash-2.05b#

• Ok these repos should be allset 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:

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 bash-2.05b#

• check where the svnserve binary is located:

bash-2.05b# which svnserve /usr/local/bin/svnserve bash-2.05b#

• 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:

bash-2.05b# cat /sbin/svnserve #!/bin/sh # wrapper script for svnserve umask 007 /usr/local/bin/svnserve -r /path/to "$@" bash-2.05b#

• 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:

bash-2.05b# 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 bash-2.05b#

• we can also check the perms for remote users like this:

cdowns:~ ~$ svn ls svn+ssh://server.domain.com:/reponame ++server.domain.com++ dev/ qa/ release/ cdowns:~ ~$

En pocas palabras...
svnadmin dump /usr/local/svn > /var/dump-svn20090915.dump
