Examples of full database backup:

# cd redis-dump/bin

#. / redis-dump-u 127.0.0.1 > / root/shell/20180928/db_all.json

An example of backing up only a library in redis:

First of all, write some data to Library 10:

# redis-cli

127.0.0.1 select 6379 [1] >

OK

127.0.0.1 set China World 6379 [10]

OK

127.0.0.1 set love chenfeng 6379 [10]

OK

127.0.0.1 set fuck America 6379 [10]

OK

Back up only Library 10:

#. / redis-dump-u 127.0.0.1-d 10 > / root/shell/20180928/db_10.json

View the content:

[root@alpha-mongo-140-52 ~ / shell/20180928/redis-dump/bin] # cat / root/shell/20180928/db_10.json

{"db": 10, "key": "fuck", "ttl":-1, "type": "string", "value": "America", "size": 7}

{"db": 10, "key": "love", "ttl":-1, "type": "string", "value": "chenfeng", "size": 8}
