I followed guides to get running on testnet and then “trashed” everything again to start from scratch. For preparation I actually built a script based on the guides that handles a lot of getting up and running. eg. I can now probably be up in less than an hour with a full reinstall.
However it doesn’t solve the issue of having to sync again. For Geth an infura failover can do but one still needs to sync the beacon chain . how long does that actually take on mainnet? On testnet for me it’s about 1 day (=24hrs). So one still loses a full day (not accounting for possible hardware to arrive).
Do you guys create a chain backup now and then? (but with clonezilla this will lead to some downtime as well). Or some other means of backing it up that doesn’t need downtime?
