@jsalvador Now, depending on the database server used by mastodon and how they're configured, the database can be stored in several different places. One common database is MySQL. The actual data is (usually) stored in /var/lib/mysql and (in some cases) can be backed up just by copying those files. With MySQL you could also use the mysqldump command to save all the data in an SQL file. So, it's a bit more of a project than I can explain in 500 characters...
