 ### How to perform a system backup
 
+There are two sources of truth for MyJekyllBlog that should be backed up regularly.
+
+The first is the installation of Gitea, a Git Service, that MyJekyllBlog uses for storage and atomic changes of all Jekyll blogs it hosts.
+
+The second is the PSQL database for mjb.panel.  This database contains all of the information about user accounts, blog ownership, etc.
+
+#### Backup Gitea Data
+
+Take a root shell on the store machine and stop gitea.
+
+```bash
+systemctl stop gitea
+```
+
+Confirm that gitea is stopped by going to the store server over HTTPS.  You should recieve a 502 Bad Gateway error.
+
+```bash
+su - git
+cd /var/lib/gitea/
+./gitea dump --c /etc/gitea/app.ini
+```
+
+There will be a file with a timestamp, such as `gitea-dump-1669000424.zip`.  This is the backup of all Gitea data and can be used to restore the repositories.
+
+Remember to start Gitea again.
+
+```bash
+systemctl start gitea
+```
+
+#### Backup PSQL Data
+
+Take a shell for the manager user on the store server and run the following.
+
+```bash
+cd mjb/Web
+./script/mjb db_dump > psql-backup-`date +%s`.sql
+```
+
 ### How to perform a system restore
 
+#### Restore Gitea Data
+
+See https://docs.gitea.io/en-us/backup-and-restore/#restore-command-restore for information on processing the gitea-dump-timestamp.zip file.
+
+#### Restore PSQL Data
+
+Instructions -- I should make an ansible task that handles this.
+
+Drop table, create table, import SQL dump.
