How to backup one cloud to another cloud?

Question

Backup

Available: Bitrix24 Disk, where the employees' file washer is located, access to the disk is carried out only via WebDAV
Required: Copy all files from Bitrix24 Disk to another cloud, accessed via FTP, SMB and WebDAV
Many backup programs offer to copy files from a mounted disk , but there is one caveat. WebDAV in Windows falls off (for example, after rebooting the machine). I want the program to authorize itself via WebDAV I am
considering both paid and free options
Do not offer batch files, I will be very grateful to everyone who has not passed by

HandyBackup can.
WebDAV backup presumes utilizing a WebDAV data transferring protocol either as data source or as a destination, or for both sides (ie for WebDAV sync data).
