Question about Rocketpool Node Backup

Hello r/ethereum

I have recently set up a rocketpool node that is synced with minipools initizalized.

I am learning about "backing up" my node from the Rocketpool Docs/Guides and am confused about something. Below is from the Rocketpool Docs and represents the different tabs of instructions relating to each topic.

As you can see here, "Consensus Client / ETH2 Client Chain Data" is listed in the "Items that should not be backed up" section, along with the "private keys and passwords"

Question 1: Why shouldn't Consensus Client data be backed up?

Additionally, if I click on the Consensus Client / Eth2 Client Chain Data option shown above, it brings me to the part of the guide that describes backing up the eth1 client data as if I should back it up like the Execution Client data.

The only thing I see listed for backing up the Eth2 client data in the guides specifically shows that Eth2 client data isn't as big of a concern since you can just checkpoint sync.

I was unable to successfully checkpoint sync while I was setting up my node and was forced to sit for weeks+ for it to sync from genesis and I am trying to avoid having to do that again.

Question 2: If I have Eth1 Client data backed up but not the Eth2 Client data (because I am unsure of wether or not it is a good idea to back up the Client 2 data as per the guide), wouldn't it still take an absurd amount of time to resync the Eth2 data if I cannot manage to get the checkpoint sync working?

​

I hope I have summarized my questions well enough. Looking for people who have experience in backing up their node client data. Please and Thank you.
