# Backing up ownCloud

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

1. The config folder
2. The data folder
3. The database

## Backup Folders

Simply copy your config and data folder (or even your whole ownCloud install and data folder) to a place outside of your ownCloud environment. You could use this command:

    rsync -Aax owncloud/ owncloud-dirbkp_`date +"%Y%m%d"`/

## Backup Database

### MySQL

MySQL is the recommended database engine. To backup MySQL:

    mysqldump --lock-tables -h [server] -u [username] -p[password] > owncloud-sqlbkp_`date +"%Y%m%d"`.bak

### SQLite

    sqlite3 data/owncloud.db .dump > owncloud-sqlbkp_`date +"%Y%m%d"`.bak

### PostgreSQL

    PGPASSWORD="password" pg_dump owncloud -h [server] -U [username] -f owncloud-sqlbkp_`date +"%Y%m%d"`.bak
