ULYSSIS takes backups of all files, databases, settings and repositories 1-4 times a week. These backups can be restored in case of severe server failure or in case of an emergency (if for example a user by mistake deletes all of their site). It is, however, more convenient that users take their own backups when they do experimental things on their account.
You can use the graphical methods described in Accessing your files to download a copy of all of your files. This copy, or certain files, can then easily be uploaded again using the same method to restore backups
If you are backing up and/or restoring a larger database, it's advised to use command line tools since they are more performant than webtools and don't have any timeouts that could interrupt your backup/restore.
To take a backup, execute the following command on one of our shellservers (with the right database name filled in):
mysqldump -h mysql.ulyssis.org -p username_database > backup.sql
This will prompt you for your database password (please refer to Using MySQL if you don't know your password) and then dump the entire database to backup.sql file as SQL.
To restore your backup you can use the mysql command on one of our shellservers (with the right database name filled in), whatever SQL file you specify will be executed:
mysql -h mysql.ulyssis.org -p username_database < backup.sql
Please keep in mind that by default mysqldump includes statements in the SQL file that will delete all tables that will be restored.
