Ruby Backup gem在上传到S3时失败。 37分钟后重置连接

Question

The backups are 250MB. I don't think that's very big, but it appears the problem is increasing with the size.

Log from the Backup gem below.

Note the time span; about 37 min into the uploading I get connection reset.

[2015/10/30 09:20:40][message] Storage::S3 started transferring '2015.10.30.09.20.01.myapp_postgres.tar' to bucket 'myapp-backups'.
[2015/10/30 09:57:06][error]   ModelError: Backup for Back up PostgreSQL (myapp_postgres) Failed!
[2015/10/30 09:57:06][error]   An Error occured which has caused this Backup to abort before completion.

Answer 1

Did you try the error handing options, which retransmit the file's portions that have failed :

store_with S3 do |s3|
  s3.max_retries = 10
  s3.retry_waitsec = 30
end

Keep also the chunk size small:

store_with S3 do |s3|
  s3.chunk_size = 5 # MiB
end

You may also want to use the Splitter options .

Answer 2

I wuold say for now to use ruby-xz to compress in a smaller file in order to send it more compressed and temprary patch it, then try to see

Excon.defaults[:write_timeout] = 500

or more would do the trick
