When the child process to complete the writing of a new RDB file, Redis replace the original file with the new RDB RDB file, and delete the old file RDB.
This way of working makes Redis can be copied benefit (copy-on-write) from the write mechanism.
File only append operations (append-only file, AOF)
snapshot feature is not very durable (durable): If for some reason Redis caused downtime, the server will lose the most recently written, and still save a snapshot those data. Although for some programs, the durability of data is not the most important consideration, but for those who seek complete program endurance capacity (full durability) of, the snapshot feature is not as useful.
From version 1.1, Redis adds a completely durable persistent way: AOF persistence.
You can open AOF function by modifying the configuration file:
appendOnly yes
From now on, whenever a change Redis execute command data sets (such as SET), this command will be appended to the end AOF file.
In this case, when Redis restarted, the program can achieve the purpose of reconstruction data sets by re-executing commands in the file AOF.
