This script actually doesn’t uploads backup to Google Drive. It uploads it to the transfer.sh website and only uploads download URL to gdrive. Someone might find it useful but I find this quite unsafe.
This script actually uploads to GDrive: GitHub - xaksh/gdrive-backup-cyberpanel: Automate Backup of CyberPanel hosted Websites to Google Drive and with easy mod you can use it to upload to many cloud storage which rclone tool does support (I use to upload to Mega.nz for example).
