It’s important to make backups of your game database and files. There are many ways to do this, a few of which are discussed here.

Here are the things that you need to back up in order to protect your game from disaster:
The Redis database periodically dumps your database to a file on the server. If you used the standard install scripts on Digital Ocean, your database file should be located in
/var/lib/redis/dump.rdb. Otherwise, you probably installed redis yourself so hopefully you know where you installed it!
Everything in your
aresmush/game folder is custom for your game. This includes your connect screen, configuration files, and Web Portal file uploads.
Ares' automated backup tools do not include source code. It's assumed that you're either using GitHub (which is an awesome way to protect your code that provides other benefits too) or that you're making changes on your local computer and uploading them through FTP. Making code changes directly through the server shell without version control is not advisable. If you choose to do so, you'll need to decide on your own backup strategy.
The next few sections will give you different options for backing up your game, listed in order from most reliable to least reliable.
If you are using a Digital Ocean droplet, you can use their Automatic Backup feature to create a weekly backup of your entire server. This includes the database, the code, the server config - everything.
This is the most robust form of backup strategy, but it costs a little extra. As of 2/18, automated weekly backups of the standard Ares droplet size cost $1/month.
AresMUSH can automatically perform daily backups to Amazon’s S3 storage service for a safe, off-site storage solution.
AWS is a great backup option, but AWS' menu options can be overwhelming for novice server admins. Make sure you're familiar with their cost tiers. Most games should fit comfortably into their 'free tier' and cost you nothing; however, it's your responsibility to understand their pricing tiers and know what you're signing up for.
To set up automatic backups, you’ll need:
Even if you use S3 for other things, create a separate bucket just for your AresMUSH backups. Ares will delete older files to make room for new backups, and you don't want it to accidentally delete anything important!
Once you have an S3 account, you’ll need to configure the game to use it.
Enter your AWS access key, bucket name and the code for the region your bucket is in into the AWS section. You can find the AWS region codes here.
There are many moving parts in the AWS backup process. Once you have it all set up, we recommend that you test it once using the manual
dbbackup command. Make sure that the database file ends up in your S3 bucket successfully before relying on the automatic daily backups.
AresMUSH will periodically back up your database and game folder to the local server. This isn’t a great backup strategy (since your backups will be toast if anything happens to the server itself) but it’s better than nothing. Edit the backup type (explained below) to ‘local’ to enable automated local backups.
Backups are stored in your
You can manually FTP the database dump file and game files to your local hard drive for a simple backup. The catch is you need to remember to do this periodically!
For the automated backup strategies (local or AWS), there are a few things you’ll want to configure.
Set the backup type to ‘aws’ for AWS backups and ‘local’ for local backups.
You can configure the number of backups the game keeps. By default this is 5. Older backups are automatically deleted.
You can configure when backups are done. By default it’s early morning, after peak MU* times. See the Cron Job Tutorial for help if you want to change this.
If you used the standard install scripts, the game should already be configured with the proper database file location. But if you performed a custom installation, you’ll need to tell the game where the database file is.
In the event you need to restore a backup, see Restoring Backups.
