Yeah it is but it’s a pretty capable laptop. I’ve replaced mine with a Framework 11th gen for my daily use but my T480 is currently hosting 10 VMs for my homelab. It’s got the base CPU, i5-8250U, 64GB of RAM and a 4TB SSD and is plenty of horsepower. I really only got the Framework because I was excited about the product and company, not because I was unsatisfied with the T480. I highly recommend it.
Syncthing may fit the bill.
