offsite backup to my home

[Big Jim]

As per title.

I would like to backup the E drive of my shop server to my home network overnight every night if possible, I would like to automate this process if at all possible.

For reference the E drive of the server does not contain system/windows files.
I can do a first time backup using an external hdd the first time so that I don't have to upload GB upon GB of data the first time.

I am probably looking daily less than 100MB to backup (on occasion will be several GB but that will be rare)
I currently use syncback in the building to do hourly syncs to another machine in the shop, but really want a realiable way to get the data backed up off site as well.

What options do I have ?
