Resolved: Instant Recovery Cannot Create Datastore [Troubleshooting Steps]

Instant recovery can restore a virtual machine in a very short period of time, but you may encounter the problem that the instant recovery process is unable to datastore. This next article discusses the causes of this problem and provides solutions to help you recover your data in the shortest possible time.

Why Datastore Creation Fails in Instant Recovery

There are several reasons why a datastore may fail to be created during the instant recovery. These issues are typically related to storage configuration, resource availability, or permissions. Below are some common reasons for datastore creation failure.

1. Insufficient Storage Capacity

When your storage system does not have enough capacity, the process of creating a datastore will fail because Instant Recovery requires a certain amount of space, depending on the size of the backup image and system requirements.

2. Insufficient Datastore Permissions

This problem is also encountered when a user lacks the permissions necessary for Instant Recovery, specifically, the permissions to create and mount storage volumes on the host server.

3. Snapshot or Backup File Issues

Corrupt or incomplete backup files can impede datastore creation. Instant Recovery relies on intact snapshot files for establishing temporary datastores. If files are corrupt or missing, the recovery software may fail to load them, jeopardizing your recovery efforts.

Steps to Resolve Instant Recovery Cannot Create Datastore

If you are facing issues with VMware instant recovery being unable to create a datastore, you can try the following troubleshoots to resolve.

1. Verify Permissions

▶Permissions on vCenter/ESXi Hosts: Check that the user account has the necessary permissions on the vCenter or ESXi host to manage the datastore. Instant Recovery typically requires full administrator privileges.

▶Storage Permissions: Ensure the account has access permissions for the storage where the datastore will be created.

2. Check Network and Connectivity

•VMware Backup Server: Ensure that the VMware backup server can connect to the vCenter or ESXi hosts over the network.

•DNS Resolution: Verify that the DNS names of the ESXi hosts and vCenter servers can be resolved from the backup server.

•Firewall Rules: Check if any firewall rules might block connections to vCenter or ESXi.

3. Storage Availability and Configuration

★Storage Device Status: Confirm that the ESXi host can access the storage device, ensuring that the storage is healthy and available.

★NFS/iSCSI Configuration: Check that the datastore's NFS or iSCSI configuration is correct and the storage is mountable. Also, ensure any necessary ports (like NFS 2049) are open.

🎈Follow simple steps to set an instant restore

Step 1. Navigate to Task > + Create New Instant Restore, and you can choose Restore from task or Restore from local path. The following is choose Restore from task as an example.

Step 2. In Source, click Select to choose VM and version.

Step 3. In Select Virtual Machine, click Select to choose the virtual machine and backup version.

Step 4. To choose target device in Restore to.

Step 5. Then you can set the hardware settings for the new virtual machine, such as CPU quantity, CPU Cores, and memory size.

Step 6. Click Start Restore to begin the instant restore.

Conclusion

The proper use of instantaneous recovery tools to minimize downtime can only be achieved if you have successfully created a data store. Failure of Instant Recovery to create a datastore can be effectively resolved by verifying resources, checking permissions, ensuring compatibility, and all other measures.
