Make a ball on Debian and drive backups there through some Veeam Backup.

Answer 2

Need a backup of the entire server or just the shared directory?
If only a directory, then the easiest way is to run a script on the side of the destination server that will connect to the directory, archive it, saving it locally, and then disconnect from the source server, unmounting the share.
If you need a snapshot of the entire source server (OS + information), then you can’t do without additional software (Acronis, Veeam, etc.)

Answer 3

From bash/cmd/powershell/etc scripts to veeam/bacula and more, what if all you need is git?. Without the conditions of the task, it is impossible to say unambiguously, you need to clarify everything.
For most tasks, veeam can be suitable, especially given how simple its interface is.
Backup what? Regular files? Databases? Virtual machines? Image? Infrastructure cloud? System states, down to running processes? What circumstances should be taken into account, what goals are you pursuing? Because for some situations, backups of a month ago are ok, and for some other operations, you will lose a couple of million records in the database per hour (and in the backup everything lost its integrity a long time ago) date sensitive with huge damage to the company.
