It’s important to manage the backup of your client’s account from your cPanel accounts. Unfortunately, cPanel hasn’t come up with any automatic backup via WHM as a reseller, so it requires logging into each account to make a backup.
Many users rely on the WHPEasyBackup service for bulk backup management, but it can be expensive, and the free trial won’t meet all your needs.
Luckily, there’s an open-source tool called cPBackup that works just fine for the task. Using the cPBackup script, you can also upload files to Dropbox from a reseller account. It is built on the official API of cPanel.
You can also utilize the method that conbines cPanel’s pkgacct script and WHM’s API listaccts.
