Can we get the logs From S3 Bucket

Is it possible to get the logs that pushed to the S3 bucket from the host.

It's not really clear what you are asking here, can you rephrase?

We are daily taking a backup of our System/Application logs to AWS S3 bucket. Now we would like to get these logs from the S3 Bucket that we are backed up.
Is it possible to connect the logstash to S3 to get the logs that are pushed to the S3 bucket.

Yes, see
