Redis data recovery method, Redis-port tool synchronizes a self-built Redis Rdb file to a cloud database

1. The Redis recovery mechanism

• If only AOF is configured, the AOF file recovery data is loaded when the reboot is restarted;
• If both RDB and AOF are configured, the boot is only loaded with AOF file recovery data;
• If only the RDB is configured, startup is the load dump file to recover the data.

2. Recovering data from AoF

1 Note the following configuration

yesdir /home/redis/data_6379/

2 Copy the AOF file to the Redis data Catalog

cp appendonly.aof /home/redis/data_6379/

3 Start Redis-server

redis-server redis_6379.conf

3. Recovering data from an RDB file

1 Note the following configuration

nodir /home/redis/data_6379/

2 Copying an RDB file to a Redis data Catalog

cp dump.db /home/redis/data_6379/

3 Start Redis-server

redis-server redis_6379.conf 

Use the Redis-port tool to synchronize a self-built Redis Rdb file to a cloud database download Redis-port

Redis-port Address

Using the example

1. ./redis-port Restore--input=x/Dump.Rdb--Target=Dst_host:Dst_port--Auth=Dst_password[--Filterkey= "STR1|STR2|STR3" ][--targetdb=db] [--] [--bigkeysize=size [-- Logfile=redisport.

Parameter description

• x/dump.rdb : Dump file path for self-built Redis

• dst_host: redis domain name for cloud database

• dst_port : Redis Port for Cloud databases

• dst_password: redis password for cloud database

• STR1|STR2|STR3: Filter for keys with str1 or str2 or STR3

• DB: DB that will synchronize the cloud database Redis

• Rewrite: Overwrite the key already written

• Bigkeysize=size: When the value written is greater than SIZE, go to large key write mode

View data synchronization status based on Redis-port log

restore: rdb donedata synchronization is complete when it appears.
