Redis Persistence What if the AOF file goes wrong?

The server may be down when the program is writing to the AOF file, and if the outage causes a AOF file error (corrupt), then Redis will refuse to load the AOF file when it restarts, ensuring that data consistency is not compromised.

When this happens, you can fix the AOF file with the error in the following ways:

1. Create a backup of the existing AOF file.
2. Use the program that came with Redis to redis-check-aof fix the original AOF file.

$ redis-check-aof--fix

3. Optionally, use a backup of the diff -u AOF file and the original AOF file to view the differences between the two files.
4. Restart the Redis server, wait for the server to load the repaired AOF file, and perform data recovery.
