Configure

svnbak.pl Configuration Section

At the top of svnbak.pl is a "Configuration Section" that you must add specific information to in order for the script to work.

• reposDir: full path to your Subversion repository, or the parent directory of all your repositories.
• destDir: full path to the directory where the backups should be saved. To save backups to a network file system, first mount the file system, then specify the mounted path.
• maxBaks: maximum number of backups to retain. Once this limit is reached, the script will automatically remove the oldest backup based on it's last modified time.
• svnBakMethod: type of Subversion backup to create ('hotcopy' or 'dump').
• tarballName: the name of the backup file. Each backup file will be appended with a 14 digit time stamp to preserve singularity.
• tmpDir: full path to a new temporary directory to store files before tarballing. This directory should not be an existing directory - it will be deleted!
• emailPref: when the admin should receive emails ('always', 'errors', 'none').
• displayTime: display execution time in seconds, per task.
