Data Recovery and Space Management Issues and FAQs
If an EBS volume attached to an instance becomes corrupted or fails, the Q-Cloud Protect appliance enters diagnostics mode and sends an alert to warn you of the issue. You can recover the data in the failed EBS volume by using the volume's EBS snapshots to create a new AMI.
For detailed instructions, see Recovering When EBS Volumes Fail
If a NAS share or VTL partition is lost or damaged on the source system, you can failback the share or partition to the source system from a received snapshot on the target system. When you failback a share or partition , it is restored on the source system just as it was at the point in time when the snapshot was saved.
For detailed instructions, see To recover data from a lost or damaged share or partition, see To recover data from a lost or damaged share or partition, see Restore the share or parition to its original location on the source system (see
Q-Cloud Protect uses the AWS cloud storage service, S3, to store all deduplicated data that is replicated to the appliance. It stores metadata separately in the EBS volumes attached to your Q-Cloud Protect instances. When either storage area becomes low, the cloud appliance sends an alert.
When you purchase a Q-Cloud Protect metered AMI, its maximum storage capacity is predefined. You will be able to use up to the specified amount of storage allocated to the launched instance.
Q-Cloud Protect offers two sizes of metered AMIs:
- 1-20 TB of storage capacity
- 1-90 TB of storage capacity
When you purchase a capacity-based license for Q-Cloud Protect to use within the GovCloud or C2S regions, you are predefining the maximum amount of storage capacity with the license. You will be able to use up to the specified amount of storage allocated in the license. Keep in mind that AWS will not charge you for storage until you actually back up data to the cloud appliance. If you begin to approach maximum storage capacity, you will need to contact your Quantum representative to purchase additional storage capacity.

If your storage capacity for replicated data reaches low levels, you will need to do one of the following:
- For metered instances in AWS Marketplace, purchase a larger Q-Cloud Protect AMI, launch the AMI as a new Q-Cloud Protect instance, and begin replicating data to the new, larger appliance. See Task Overview: Launch Instances from AWS Marketplace.
- For licensed instances in GovCloud or C2S, purchase additional licensed capacity to increase storage for the appliance. After purchasing additional storage capacity, you may also need to increase the size of the instance type and expand the instance's EBS volume. See Expand Capacity for Licensed Cloud Appliances.
- Remove replicated data stored in S3.
