Restore Database
----------------
Clean Database Before Restoring
===============================
.. warning:: Before restoring a backup you need to make sure to delete all existing database tables.
The easiest way to do this is to drop and recreate the database.
SQLite does this automatically.
MySQL
^^^^^
MySQL is the recommended database engine. To restore MySQL::
mysql -h [server] -u [username] -p[password] -e "DROP DATABASE nextcloud"
mysql -h [server] -u [username] -p[password] -e "CREATE DATABASE nextcloud"
If you use UTF8 with multibyte support (e.g. for emoijs in filenames), use::
mysql -h [server] -u [username] -p[password] -e "DROP DATABASE nextcloud"
mysql -h [server] -u [username] -p[password] -e "CREATE DATABASE nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci"
PostgreSQL
^^^^^^^^^^
::
PGPASSWORD="password" psql -h [server] -U [username] -d nextcloud -c "DROP DATABASE \"nextcloud\";"
PGPASSWORD="password" psql -h [server] -U [username] -d nextcloud -c "CREATE DATABASE \"nextcloud\";"
Restoring
=========
.. note:: This guide assumes that your previous backup is called
"nextcloud-sqlbkp.bak"
