    Tezos Rolling Mode Guide (How To)

Running Tezos in this mode will only store the blocks after latest snapshot, no longer requiring hundreds of gigabytes of drive storage space.

The software modification is provided by Nomadic Labs, details: https://blog.nomadic-labs.com/introducing-snapshots-and-history-modes-for-the-tezos-node.html
Upgrade only:

rm -rf tezos
wget https://gitlab.com/nomadic-labs/tezos/-/archive/mainnet-snapshots/tezos-mainnet-snapshots.zip
unzip tezos-mainnet-snapshots.zip
cd tezos-mainnet-snapshots
git checkout mainnet
make build-deps
make


If it fails:
opam update
opam pin list -s | xargs opam pin remove
make build-deps
make

Run node, no changes for other parts:
./tezos-node run --rpc-addr 127.0.0.1:8732 `bash get_peers.sh` --history-mode rolling
Full procedure:

sudo apt install bubblewrap
sudo apt install zip
wget https://gitlab.com/nomadic-labs/tezos/-/archive/mainnet-snapshots/tezos-mainnet-snapshots.zip
unzip tezos-mainnet-snapshots.zip

Create an identity, start RPC server, add address, activate:
./tezos-node identity generate 26


echo "curl -s 'http://api.tzscan.io/v2/network?state=running&p=0&number=50' | grep -Po '::ffff:([0-9.:]+)' | sed ':a;N;$!ba;s/\n/ /g' | sed 's/::ffff:/--peer=/g'" > get_peers.sh 

./tezos-node run --rpc-addr 127.0.0.1:8732 `bash get_peers.sh` --history-mode rolling
./tezos-client add address fundraiser <tz1...> 
./tezos-client activate fundraiser account fundraiser with <activation_key>

To import your fundraiser private key:
./tezos-client import fundraiser secret key fundraiser
Start baking (background service &), path to your node location:
./tezos-baker run with local node "/home/**user**/.tezos-node"
./tezos-endorser run "fundraiser"
./tezos-accuser run
