Redis Data Persistence aof mode

Open the running directory for Redis, select Database 2 (select 2, empty set) to see the last save time for Dump.rdb is 1:58 noon today.

Add 2 data:

View Dump.rdb again, save time is now (description from 1:58 to now no modified key)

You can see the data that you just saved in Dump.rdb, but when you add a third data ADDR3, the modification time of DUMP.RDB is not changed and the snapshot backup frequency is not reached.

Now choose the label of 3 database, add 2 data, at this time not reached the frequency of snapshot persistence, so the default DUMP.RDB does not have these two data, DUMP.RDB should be modified time is 4 points more

You can manually initiate snapshot persistence at this point, and you can see that the backup file modification time has changed.
