When Solana restarts, it redownloads the snapshot. causing the data block to lose. For example synchronize to block height 203000000 before restarting. After rebooting download snapshot, the block height starts from 203002000, which results in 2030000-203002000 blocks lost, how to solve this issues?
I set --limit-ledger-size=70000000, the theory is to retain 3 days+data

Pass --no-snapshot-fetch in the command line to start from the node's local snapshot instead of downloading a new one.
