Backups by Verploy. Every night Verploy makes a backup of each site through the connector, on the hosting your clients already use, without needing access to the hosting account. The first backup is complete; after that only what changed, plus the database each time. Backups are encrypted on the site before they leave it (the key stays with Verploy), stored in the EU and kept for 30 days. “Back up now” on the site page.
Restore per site. Only that website (files and its own database tables) is restored: first prepared next to the live site, then switched in one step, then checked. If the site does not work afterwards, Verploy automatically puts the previous state back. wp-config.php, the connector and the pairing with Verploy are left in place.
