InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Power-hungry: In my experience, this is not a problem. My T460 with an extended battery gets more than 10 hours of battery life, although I don't do a lot of web browsing. Newer Intel hardware is hampered by a lack of HWP support in upstream Xen. There are experimental patches for this which I have tested on an i5-8365U which seem to make a big difference. https://github.com/QubesOS/qubes-issues/issues/4604#issuecomment-793077574
Backups: This is a major problem for internet-isolated VMs. For internet-isolated VMs, I use this tool: https://github.com/tasket/wyng-backup. But it does only backup the Qube from the shutdown state. The Qube doesn't need to be shutdown, but it doesn't use the live volume. (You can actually run it on live volumes, but it's not supported for that.) In internet-connected VMs, I just use restic or borg. You're right that an offline backup solution is actually more complicated in this regard. The simple way of attaching a USB drive will only attach to one Qube at a time. Now there should be a way to attach the USB drive to only a backup qube, and do some sort of passthrough between the Qubes, but I don't know exactly how to do this.
