Backup

What to back up

• ./data/ - required. You can skip cache/ and favicons/; FreshRSS rebuilds them.
• ./extensions/ - recommended if you use third-party extensions.
• ./i/themes/ - optional, only if you have added custom themes.
• External database (MySQL, MariaDB, or PostgreSQL) - back up separately with mysqldump/pg_dump. SQLite is covered by ./data/ above. See Exporting your data for per-user SQLite export.

All other folders belong to the source code and are restored by a fresh install or upgrade.

Full installation backup

Do this before an upgrade.

The following commands assume your FreshRSS directory is /usr/share/FreshRSS; substitute your path if installed elsewhere.

ℹ️ It is safer to stop your web server and cron during maintenance operations.

Creating a database backup

Back up each user's database to ./data/users/*/backup.sqlite:

cd /usr/share/FreshRSS/
./cli/db-backup.php

Creating a backup of all files

Save the backup to your home directory:

cd ~

Create a gzipped tar archive of the FreshRSS directory:

tar -czf FreshRSS-backup.tgz -C /usr/share/FreshRSS/ .

Restoring files from a backup

Extract the backup into your FreshRSS directory:

tar -xzf ~/FreshRSS-backup.tgz -C /usr/share/FreshRSS/

Restoring a database backup

Restore each user's database from ./data/users/*/backup.sqlite:

cd /usr/share/FreshRSS/
./cli/db-restore.php --delete-backup --force-overwrite

Migrating the database

First, back up all user databases to SQLite files:

cd /usr/share/FreshRSS/
./cli/db-backup.php

Change your database setup:

• to change the database type (e.g. from MySQL to PostgreSQL), edit ./data/config.php accordingly.
• to upgrade to a major PostgreSQL version, after a PostgreSQL backup, delete the old instance and start a new one (remove the PostgreSQL volume if using Docker).

Restore all user databases from the SQLite files:

cd /usr/share/FreshRSS/
./cli/db-restore.php --delete-backup --force-overwrite

See also our Docker documentation for migrating the database.

Backing up selected content

Feed list export

You can export your feed list in OPML format either from the web interface, or from the command-line interface.

The OPML export only includes the standard OPML parameters; it omits FreshRSS-specific attributes like refresh frequency, credentials, user agent, and XPath web scraping rules.

For a full export including these, use the SQLite export described below.

Exporting your data

MySQL or MariaDB

You can use phpMyAdmin or mysqldump. Replace <db_user> with your database username, <db_host> with your database server hostname, and <freshrss_db> with the FreshRSS database name:

mysqldump --skip-comments --disable-keys --user=<db_user> --password --host <db_host> --result-file=freshrss.dump.sql --databases <freshrss_db>

Any database

Export your database to a SQLite file with the command-line interface:

./cli/export-sqlite-for-user.php --user <username> --filename </path/to/db.sqlite>

Import the SQLite file back into your database:

./cli/import-sqlite-for-user.php --user <username> --filename </path/to/db.sqlite>

ℹ️ The database filename must use the .sqlite extension for both commands to work.

The export/import flow is useful when you need to:

• fully export a user,
• back up your service,
• migrate the service to another server,
• change the database type,
• fix database corruption.
