That's a big plus.
Currently, cPanel is experiencing a decline. If it continues to increase prices, its price will soon reach a point where it will no longer make sense to use it. But we still want backup formats to be cPanel's native backup format.
The same applies to other control panels. Backup formats need to be in the native control panel backup format. This alone will eliminate many backup-related errors.
I asked the same thing back in April and Brijesh said
Regarding the structure I think it will be difficult to preserve the cPanel backup structure as we will need a unified backup structure to restore across panels.
So it'd be like JetBackup. The only one I know that retains the default cPanel backup structure is cPremote, but it lacks essential features that JetBackup has, such as a progress bar for the backup and restore process, showing how many accounts remain to be backed up or restored. As we know, they're supposed to be releasing a new version of cPremote called Enterprise, but no updates on that yet. The current cPremote is used on Eenos control panel.
I think it's odd that Backuply Pro is free for cPanel users if they are already using Softaculous, as some have dropped Softaculous because cPanel already includes WP Toolkit.
I had switched some VPS from cPanel to Webuzo as the client wanted to save on licensing costs from cPanel, and at the time, Backuply for Webuzo was free. After switching to Webuzo, it started charging $5/month extra for each VPS to use Backuply, with incremental backups (full/compressed is free). However, since there is limited space on VPS, we couldn't use full/compressed, and therefore had to pay the extra $5/month for all VPS, which increased the price. The client wasn't that happy about that. Still, the cost of Webuzo and Backuply is less than cPanel/WHM and its outdated backup system.
I allowed the client to continue using Webuzo, but I decided not to offer it as an alternative for the reasons mentioned above. Additionally, you cannot use pre-includes for Apache configuration on Webuzo, unlike with cPanel, at least not through the GUI.
Webuzo is getting there, but I'm going to give it another 6-12months or more. I check the progress periodically.
