S3 compliant

Xopero ONE supports the majority of the most popular cloud service providers compatible with S3:

• Wasabi

• Azure Blob Storage

• Backblaze B2

• Google Cloud Storage

• other S3 compliant

Configuration and limitation

Sending backup tasks to S3 cloud storage has a limit (buffer). The default buffer value is 128 MB, which limits both the maximum data size and the minimum internet speed. If your network environment or S3 endpoint has no additional restrictions, the minimum required upload speed is ~0.64 Mbit/s.

For cloud storage backup to S3-compliant systems, Xopero suggests a minimum upload speed of 2.5 Mbit/s.

Immutable storage

This feature is not enabled by default.

Xopero ONE supports S3-type immutable storage as a backup location. This feature is available for all cloud storages (AWS, Wasabi, Azure Blob Storage, Backblaze B2, and Google Cloud Storage). Datastores of this type allow you to freely save and read data, but modification and deletion are only possible after meeting the bucket’s retention policies.

Advantages:

• Protection against ransomware and other threats (cyberattacks) – files in immutable storage are read-only and immune to loss, accidental deletion, corruption, and other issues that could compromise your data.

• Prevention of accidental file deletion – when access to important or critical data is shared, the risk of deletion or modification increases, which immutable storage feature prevents.

• Preservation of file authenticity – ensures data accuracy by preventing modification or manipulation of uploaded files.

• Compliance with legal regulations – meets requirements for storing confidential data (e.g., payment or medical records).
