We run a subversion<\/a> service for a number of different research groups. Generally we create a separate subversion repository for each group. Obviously looking after this data is important. It’s not a good idea to lose months of someone’s work.<\/p>\n

Fortunately backing up a subversion repository is pretty simple. Subversion ships with a utility called svnadmin. One of the functions of which is to dump a repository to a file.<\/p>\n

As the repository owner do:<\/p>\n

\nsvnadmin dump \/path\/to\/repository > subversion_dump_file\n<\/pre>\n
I have a directory full of subversion repositories so what I really want is a script that will find all the subversion repositories in the directory and dump them with sensible filenames. With my usual lack of imagination I’ve called this script svn_backup. It runs svnadmin verify against each file in the directory it’s given. If any of them turn out to be subversion repositories it dumps them using svnadmin dump.<\/p>\n
\n$ .\/svn_backup\nsvn_backup  -s subversion_dir [-b backup_dir] [ -o logfile]\n        script to backup subversion repositories\n\n        -s      directory containging subversion repositories\n        -b      directory to dump backups to. defaults to \/tmp\n        -o      file to output names of backups to\n<\/pre>\n
So I now have an entry in cron.daily like:<\/p>\n
\nsvn_backup -s \/var\/www\/subversion -o \/tmp\/svn.log -b \/var\/backups\/svn\n<\/pre>\n
The reason I write the backups to a log file is that it allows me to run a script once a week that copies the latest backups to Amazon’s S3 storage system.<\/p>\n
The scripts:
