This tutorial demonstrates commands for backing up FreshRSS. It assumes that your main FreshRSS directory is /usr/share/FreshRSS; If you've installed it somewhere else, substitute your path as necessary.
Do this before an upgrade.
First, Enter the directory you wish to save your backup to. Here, for example, we'll save the backup to the user home directory
cd ~
Next, we'll create a gzipped tar archive of the FreshRSS directory. The following command will archive the entire contents of your FreshRSS installation in it's current state.
tar -czf FreshRSS-backup.tgz -C /usr/share/FreshRSS/ .
And you're done!
First, copy the backup previously made into your FreshRSS directory
cp ~/FreshRSS-backup.tgz /usr/share/FreshRSS/
Next, change to your FreshRSS directory
cd /usr/share/FreshRSS/
Extract the backup
tar -xzf FreshRSS-backup.tgz
And optionally, as cleanup, remove the copy of your backup from the FreshRSS directory
rm FreshRSS-backup.tgz
You can export your feed list in OPML format either from the web interface, or from the Command-Line Interface.
To save articles, you can use phpMyAdmin or MySQL tools, where <db_user> is your database username, <db_host> is the hostname of your web server containing your FreshRSS database, and <freshrss_db> is the database used by FreshRSS:
mysqldump --skip-comments --disable-keys --user=<db_user> --password --host <db_host> --result-file=freshrss.dump.sql --databases <freshrss_db>
