Your backup limitation starts from 100 and goes up to 1000. To set your backup limitations, first enabling the Backup Service, then go into the Settings tab and to the Set Your Backup Limitation box. From the drop down menu, choose the limitation that is best for your website.
10Web uses differential backup. This means we backup only the changes made since the previous backup of your site, allowing you to save storage space and time – only the first backup takes a relatively long time.
