Cloud Reader mode allows a temporary QoreStor instance to read the backup data stored in a cloud tier from another instance of QoreStor. It helps with restoring backups for auditing the data in the cloud and for testing disaster recovery using cloud data.

Continuous data protection
Continuous data protection (CDP) occurs when backup software takes frequent snapshots of a protected virtual machine (VM) and saves the backups to backup storage, where they can later be recovered. QoreStor supports CDP backups over RDA protocol. Backup software can take advantage of the deduplication and compression capabilities that QoreStor offers, and the optimized network transfers of the RDA protocol.
NetVault 13.1 backup software uses the QoreStor CDP feature for its continuous backup option.

|
NOTE: While features such as immutability, optimized copy of backups, and Cloud Tier are supported with CDP backups, the following features are not supported with CDP:
|
Synthetic full backups
CDP begins with a full backup of the protected VM and is followed by a series of incremental backups for subsequent changes. When QoreStor rolls up the incremental backups with the initial full backup, it generates a complete and current image of the protected VM called a synthetic full backup. In the backup software, you can determine how often to create these synthetic backups. For more information, see the NetVault Administrator's Guide.
Instant Restore
With CDP backups, QoreStor lets you recover data using the Instant Restore feature. Backed-up files present as a temporary datastore over Linux network file sharing (NFS) protocol. NetVault then mounts the backed-up files on an ESX host, which lets the snapshot of the VM boot directly from. QoreStor. You can then use NetVault to migrate the VM to another ESX host. For more information, see the NetVault Administrator's Guide.
Compatibility
QoreStor supports the CDP feature with NetVault 13.1 and later. CDP is compatible with the following NetVault plug-ins:
- NetVault Plug-in for VMware 13.1 and later
- Plug-in for Microsoft 365 13.2.5 and later.
Disaster Recovery from the cloud
When configured with a Cloud Tier or Archive Tier, QoreStor provides the ability to capture QoreStor configuration information as well as storage group and container data. With this information, it is possible to re-create a lost or failed QoreStor server using the data in the cloud. Please note that the data which is not cloud replicated and is still present in the local disk is not recoverable in case of a failure with the primary QoreStor.
Cloud tier disaster recovery
In the event of QoreStor server failure, a recovery can be initiated on a new, licensed QoreStor server to restore from the previous configuration stored in the cloud. At a high-level, a recovery will go through the following steps:
-
Connect to your cloud provider with configured credentials and passphrase.
IMPORTANT: The required passphrase is the passphrase used when creating the Cloud Tier. Without the Cloud Tier passphrase recovery cannot proceed.
- The new QoreStor will read the stored configuration once it is connected to the cloud .
- Rebuilds the cloud-replicated containers as well as other storage groups and containers.
- Runs the filesystem check and brings the QoreStor to a consistent state.
For more information refer to Performing a disaster recovery from the cloud.
Archive tier disaster recovery
When performing data recovery from an Archive Tier, you must first restore all datastores to standard AWS S3 storage using the AWS Management Console. For more information refer to Manually restoring datastores from Amazon S3 Glacier and Restoring from an archive tier.
Supported file system protocols
QoreStor supports the following file system protocols. The Rapid Data Access (RDA) protocols below provide a logical disk interface that can be used with network storage devices to store data and support data storage operation.

- Common Internet File System (CIFS)
- Rapid Data Access (RDA)
- Rapid NFS
- Rapid CIFS
- RDA with OpenStorage Technology (OST)
- RDA with NetVault
- RDA with vRanger
- The virtual tape library (VTL) tape access protocols:
- Network Data Management Protocol (NDMP)
- Internet Small Computer System Interface (iSCSI)
- Other supported access protocols
- Object (S3)
