I have a license for https://whmeasybackup.com/ myself, which served me well in the past. However, I recently found out about https://whmbackup.solutions/ which appears to be an entire free, open source solution
I know, many of you guys are using DA by now, but for those who still have Reseller accounts with cPanel this might be interesting.
You might just wanna check it out: Bitbucket
yup found that free script few months back , scanned with virustotal and webshell was detected but the developer said its false flagged due to script updater he used
still using whmeasybackup , try and let us know how its goes for a setup wise both are almost same simple cron and storage setting
The code is right here - feel free to adapt as necessary.
