Backup and Restore emails in cPanel webmail
Webmail is web-based email accounts. These are usually free email accounts that are operated from a website. Examples include Hotmail, Gmail, and Yahoo Mail. Webmail allows the users to access their emails as long as they have access to an Internet connection and a web browser. This also means that the user cannot read an old email or draft a new email offline. To backup and restore the emails in cPanel, follow the below steps
Step 1 Login to the webmail.
Step 2 In order to backup (export) emails to your local computer, select the required email(s) and click on More icon in the taskbar.
Step 3 In the dropdown list, select Download (.eml) option and specify the location to save the email(s).
NOTE: .eml files are supported by most of the email services, so you can easily restore them later on different servers.
Unfortunately, Roundcube does not provide convenient functionality to download many emails at once, so if you want to back up the whole folder or account, we recommend using Horde instead.
