In /lib/systemd/network/10-eth0.network on my client, I am failing to configure anything that can translate my manual command:

sudo ip route add default via 192.168.7.1 dev eth0

where 192.168.7.1 is the static IPv4 address of my host.

My last 10-eth0.network configuration attempt:

[Match]
Name=eth0

[Link]
RequiredForOnline=no

[Route]
Address=192.168.7.2/24
Destination=192.168.7.1/32
Gateway=192.168.7.1

Refreshed with sudo systemctl restart systemd-networkd and validated with ip route (it doesn't show up).

I want to store time machine backups on a storage server running ubuntu server with an ext4 filesystem. If I only ever interact with the server over the network, will I be able to safely recover this mac backup?

Can I safely store my windows backups there as well? What utility is recommended to snapshot a windows box?

I have a 1TB external hard drive and would like to take a snapshot of the entire server periodically (maybe once a week). For cronjob part, I plan on pointing to a bash script in:

$ sudo crontab -e

but have no idea what tool I could use to make a disk image of the server while it's running. Would it have to be down while creating the image? I was looking at Clonezilla but it looks like I have to first set up a DRBL server which seems like something I don't want.

I also don't know how long it might take to run a backup or if there's any way to only do incremental changes. I plan on storing ~500GB of data there.

Do I need to format the external hard drive any particular way? Does anyone know of good tutorials/starting points?

Thanks in advance.
