Restoring instances

R‑Cloud enables you to restore an entire instance or its individual disks to a specific point in time, or multiple instances or disks belonging to multiple instances in a single session. In the event of a disaster in your environment, you can also restore instance data to a different cloud platform by using the Move Instance restore option.

Prerequisites

  • Only if you plan to specify post-restore scripts.

    • Access to the instance file system must be enabled. For instructions, see Enabling access to data.

    • A script must be available in an accessible folder.

    • The user account must have permissions to run a script on the instance.

  • For AWS: Before restoring an instance to the same or a different VPC, subnet, or region, make sure the following prerequisites are met in the location of the instance:

    • In a VPC without public IPs or in subnets without public IPs, you must create the following VPC endpoints:

      • Interface endpoints: Amazon EC2 (ec2), AWS Security Token Service (sts), Amazon SQS (sqs), and Amazon SNS (sns)

      • Gateway endpoint for Amazon S3

      For details on how to enable Amazon VPC endpoints, see AWS documentation.

    • The security group that the instance belongs to must have an inbound firewall rule for port 443 (HTTPS), source IP 0.0.0.0/0 and an outbound firewall rule for port 443 (HTTPS), destination IP 0.0.0.0/0.

      For instructions on how to configure and apply the network firewall rule, see AWS documentation.

Limitation

If your data is stored as a snapshot, you cannot restore it to a different source.

Considerations

  • Only one restore task can run at the same time for the instance.
  • Only if you excluded any of the disks from the instance backup. Keep in mind that the selected restore point will not include all the disks for the restore.
  • Only if you plan to specify post-restore scripts. The scripts are run from the home directory of the user account that R‑Cloud uses for running the scripts.

  • Depending on the operating system on the instance, the following user accounts are used:

    • For AWS and Azure instances: The user account that is assigned to the instance in R‑Cloud through a credential group.

    • For Google Cloud instances running Linux:

      • The instance has no credential group assigned in R‑Cloud: The HYCU Managed Service Account (HMSA).

      • The instance has a credential group assigned: The user account specified in the credential group.

    • For Google Cloud instances running Windows: The user account that is assigned to the instance in R‑Cloud by means of a credential group.
