Django n00b here. I'm wondering, are django fittings a trusted method to backup my data, rather than really backup in the database? Let's say my database is large?
Fittings usually are meant to house data that needs to be populated in to the database once newOrwhole application is added. This is actually for that inevitable move of the code from development to production, where you'll need this same data available soon after syncing the database.
Now, according to this function, you can most probably produce a base fixture composed of basically a database backup, but that is not necessarily what fittings are meant for.
Your best choice would be to stick to the standard practice of keep consistent and frequent SQL backup copies of the database by using cron as well as other arranging application.
