Detailed help is available by executing either script with the --help argument.
By saving the scripts to a directory in the user's PATH, you can execute them without specifying a full path. If you do not save them to a directory in the PATH, you should execute the scripts from the current directory as:
Both scripts require several pieces of information, much of which can be determined by looking at the MythTV configuration file, ~/.mythtv/config.xml. However, the backup directory must be specified. While the directory can be specified with the --directory command-line argument, since it's likely to be the same value for every run, it makes sense to add the backup directory to a backup resource file (~/.mythtv/backuprc). Do so by running the following command from a shell (not in MySQL), replacing the directory, /home/mythtv, with the desired backup directory path:
echo "DBBackupDirectory=/home/mythtv" > ~/.mythtv/backuprc
If you do not specify the directory as above, the backups will be stored to a directory defined in the DB Backups storage group, falling through to the Default storage group.
At this point, creating a backup should be as easy as running:
