Backing up your website and then restoring it when something goes wrong is absolutely critical. Web Hosting only guarantees disaster recovery services but it’s far more likely that a website will be down due to a new module misbehaving, accidental deletion of files, etc. Drupal’s drush utility makes backing up and restoring sites simple and can also be used to migrate a site from one account to another. (i.e. migrating from a development account to the production one)
You will need SSH access to your website so please request it if you don’t already have it.
This creates a snapshot backup of the website into a file called mysite.tar located in the php-data/ directory of the account.
cd /usr/local/webs/mysite/htdocs/ drush archive-backup --destination=/usr/local/webs/mysite/php-data/mysite.tar
This restores a website from a backup. Note that it will overwrite the current site and any changes you’ve made since the snapshot was taken.
drush archive-restore /usr/local/webs/mysite/php-data/mysite.tar \ --overwrite \ --destination=/usr/local/webs/mysite/htdocs
To migrate a website from one account to another you first make a standard backup as shown above. Then transfer the file to the other account. (in this case it’s placed into the php-data/ directory) You can then execute a restore; however, you will need to update the database credentials to the appropriate values for this account. drush has built this update directly into the restore command.
drush archive-restore /usr/local/webs/anothersite/php-data/mysite.tar \ --overwrite \ --destination=/usr/local/webs/anothersite/htdocs \ --db-url=mysql://dbuser:firstname.lastname@example.org/dbname
Note that dbuser, dbpassword, and dbname are for the destination account and all must exist prior to executing this command. (It won’t create any of them)
