Can I disable rdb when aof enabled?

[shaofengniu]

Hi,
Can I just disable the rdb dump when the aof is enabled?
The dump.rdb file seems to be only needed when syncing a slave with
the master. And I think the aof is more reliable than the rdp file.

Thanks

Hello,

You can easily disable RDB persistence removing the "save" statements
from the redis.conf file.
However it is generally not a good idea IMHO, you should take RDB
persistence enabled as well since it is good to have single-file
compact persistence that you can use to do backup, for disaster
recovery transferring this file out of your data center, and so forth.

A good plan involves limiting RDB dumps to 1 every hour, and use this
hourly dump of the DB for backups and other usages.

Cheers,
Salvatore

Thanks for your reply.

I agree with you that limiting RDB dump frequency to about 1 hour when AOF enabled is a good idea.

This may help reduce some "not so useful" background dumps.

Thanks again. :)
