add Google Cloud Storage / nearline to storages

[bmaeser]

in march 2015 google introduced the Cloud Storage / Nearline plattform.
using this service as a backup-storage would make a great improvement to this project.

I hadn't heard of a new google cloud storage thing, but sure, would make a nice option to save back ups there as well.

Currently the team is not working to expand current feature set. We're busy with other things, but also looking if we can improve the overal code base in a new version.

We're currently accepting community PRs for new features. So if you're able and have the time to add this go ahead! Otherwise you'll have to wait until someone has time to pick this up.

i would love to implement this myself, unfortunately i don't speak any ruby.

but thanks for putting it on the roadmap.

I'm working on this PR (at this moment, they have the best offer for backups storage)

@Bogdaan Any information about the current state? Anything we can help with?

@pduersteler
For performance and security reasons i use FUSE (https://cloud.google.com/storage/docs/gcs-fuse) with backup-local storage. FUSE create more api-calls, but it works faster that ryby implementation.

I'd love to help with this! So @Bogdaan let me know if I can help!

The Google Storage API is interoperable with S3 so that basically means all you need to do is pass the correct endpoint to fog, along with the correct access & secret keys for Google, and everything will work exactly the same.

Steps to make it work:

1. On your Google Cloud account, go to Storage -> Settings -> Interoperability and create a new Access/Secret pair.

2. The documentation link below has a reference on how to pass other options to fog, including a different endpoint: http://backup.github.io/backup/v4/storage-s3/

You can use one of the XML endpoints from this link https://cloud.google.com/storage/docs/request-endpoints (either HTTPS or HTTP should work).

I hope it helps.

I have created a new PR implementing with fog the connection to use GCS as storage.

backup/backup#827

I have seen that fog provides the XML API (using the Interoperability credentials that @rpassis said) and also the JSON API, but this one is supported in a version that is not included in fog yet as that version deprecates Ruby versions less than 2.0.0 and in fog they still support it.

According to fog/fog#3872 (comment) they are planning the change, so hopefully that one will be done soon and we will be able to have the JSON API.

Hi !

I'm trying to use GCS via S3 interoperable API, but I have the following error:

My configuration:

  store_with S3 do |s3|
    s3.access_key_id     = 'XXX'
    s3.secret_access_key = 'XXX'
    s3.bucket            = 'backup-bucket'
    s3.path              = 'web04'
    s3.region            = 'EU',
    s3.fog_options       = {
      endpoint: 'https://storage.googleapis.com',
    }
  end

My environment:

backup 4.3.0 : ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

Do I need to pass extras options ?

Thank you in advance.
