最后一次增量备份，不需要添加--redo-only
Note
--redo-only should be used when merging all incrementals except the last one. That’s why the previous line doesn’t contain the --redo-only option. Even if the --redo-only was used on the last step, backup would still be consistent but in that case server would perform the rollback phase.

Once you merge the base with all the increments, you can prepare it to roll back the uncommitted transactions
