Multiple layers of security

We know that using the same data center is not secure. That's why your data is backed up in three different physical locations.

  • Data located in Switzerland.
  • Saved in two different data centers.
  • Saved on at least 3 different hard drives, on 3 different machines, in 3 different racks.
  • The hard drives are automatically encrypted in AES-256.

Yes, this service has no egress/ingress limits. If you purchase 1 TB but download or upload 10 TB per month, it won't be an issue.

Additionally, there are no charges for API requests.

Of course, the "Fair Use" policy applies. In case of abusive use of the service, we will contact you to find a suitable solution.

No, unlike our competitors, we do not impose a limit on the number of buckets, whether it's 10 or 10,000.

Our API is similar to S3, but you cannot modify file permissions (ACL) or make files public.

We apply the OpenStack limits available here.

No, unfortunately, this is not possible due to OpenStack compatibility issues.

However, you can create an S3 gateway and use a simple proxy for your private data.

Yes, that's the main benefit of this service. If you wish to do so, simply connect our S3 backend to NextCloud, for example.

Yes, thanks to our triple replication. Even if a datacenter burns down, we will still have your data. This service is very suitable for backups or mass storage.

Yes, 256 TB, but to upload a file larger than 5 GB, you need to use multipart upload.

Yes, contact our support with the plan of your choice.

Upload speeds can vary. Often, the cause of slowdowns is your machine as it needs to hash the files.

Upload speed: from 200 Mbps to 2000 Mbps, download speed: from 400 Mbps to 8000 Mbps.

For users outside the European Union, your speeds may be lower due to submarine cables and the distance between Switzerland and your country.

When you send your files to our S3 service, a server copies your file to two other machines under specific conditions (not in the same rack, not on the same disk, and not in the same location).

No, this service is primarily designed for backups. We only offer one S3 key per backup service.

All transactions must be carried out using a valid TLS certificate. The datacenters where the data is stored are certified "ISO 27001, ISO 14001, ISO 50001".

No, if you delete data in your Poli Systems S3 service, it will be permanently deleted.
