# ownCloud 8.0 Server Administration Manual

# Restoring ownCloud

To restore an ownCloud installation there are three main things you need to restore:

1. The configuration directory
2. The data directory
3. The database

Note

You must have both the database and data directory. You cannot complete restoration unless you have both of these.

When you have completed your restoration, see the `Setting Strong Directory Permissions` section of Installation Wizard.

## Restore Folders

Note

This guide assumes that your previous backup is called “owncloud-dirbkp”

Simply copy your configuration and data folder (or even your whole ownCloud install and data folder) to your ownCloud environment. You could use this command:

    rsync -Aax owncloud-dirbkp/ owncloud/

## Restore Database

Note

This guide assumes that your previous backup is called “owncloud-sqlbkp.bak”

### MySQL

MySQL is the recommended database engine. To restore MySQL:

    mysql -h [server] -u [username] -p[password] [db_name] < owncloud-sqlbkp.bak

### SQLite

    rm data/owncloud.db
    sqlite3 data/owncloud.db < owncloud-sqlbkp.bak

### PostgreSQL

    PGPASSWORD="password" pg_restore -c -d owncloud -h [server] -U [username]
    owncloud-sqlbkp.bak
