# Supported storage types

## Storage types

**Xopero ONE** supports 9 storage types:

1. **Local directory** - a directory created on the local disk of a device with the **Xopero ONE** agent installed.
2. Network location (SMB share) - a secure network location accessible with login credentials;  communicates with **Xopero ONE** via SMBv2 protocol. Supported SMB versions include SMB 1.0/CIFS, SMB 2.0, SMB 2.1 and SMB 3.0.
3. Network File Storage (NFS share) - a network location that can be accessed <mark style="color:$danger;">only</mark> if the endpoint IP address is whitelisted; **Xopero ONE** communicates with this type of network share over the NFSv3 protocol (NFSv4 is <mark style="color:$danger;">not supported</mark>).
4. **AWS** storage - dedicated to **AWS S3** datastore.
5. **S3** storage - any **S3** compatible storage type.
6. **Wasabi** - storage type dedicated for **Wasabi S3** compatible datastore.&#x20;
7. **Backblaze B2** - storage type dedicated for **Backblaze B2 S3** compatible datastore.&#x20;

## Local storage

In onsite storage, data and storage hardware are located internally to your business organization. You may have a computer room or a data center onsite where the storage devices are securely located. All your internal systems within the same building or organization will have direct access to the storage, usually over an internal Local Area Network (LAN).

## Immutable storage

**Xopero ONE** supports **S3**-type immutable storage as a backup location. This feature is available for some of cloud storages supported by **Xopero ONE** (**AWS**, **Wasabi**, **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 <mark style="color:$danger;">after meeting the bucket’s retention policies</mark>.

Advantages:

* [x] 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.
* [x] 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.
* [x] Preservation of file authenticity – ensures data accuracy by preventing modification or manipulation of uploaded files.
* [x] Compliance with legal regulations – meets requirements for storing confidential data (e.g., payment or medical records).
