Does IDrive support incremental backups for VMware Virtual machines?

Yes. IDrive initially backs up all your data, and then performs incremental backups since the full backup. To perform incremental backup, enable Change Block Tracking (CBT).

To enable CBT,

  1. Power off the virtual machine.
  2. Right-click the virtual machine and click 'Edit Settings'.
  3. Click the 'Options' tab.
  4. Click 'General' under the Advanced section, and then click 'Configuration Parameters'. The Configuration Parameters dialog box appears.
  5. Click 'Add Row'.
  6. Add the ctkEnabled parameter, and then set its value to true.
  7. Click 'Add Row', add scsi0:0.ctkEnabled, and set its value to true.

Note: scsi0:0 in scsi0:0.ctkEnabled indicates the SCSI device assigned to the hard disk, which is added to the virtual machine. Every hard disk added to the virtual machine is given a SCSI device similar to scsi0:0, scsi0:1, or scsi 1:1. The CBT option is either enabled or disabled on each disk.

What are the ports required by IDrive application to perform backup and restore operations?

Ports 443 and 902 should be opened and be accessible on the source host to perform backup and restore operations.

How do I test the VMware connectivity to port 902?

Do I need to turn off or shutdown the Virtual machine(s) in VMware manager to take a backup?

No. You do not have to shut down your active virtual machine(s) to perform a backup. IDrive enables you to backup virtual machine(s) in their Running state.

How secure is the data transfer during backup/restore using IDrive VMware Backup?

IDrive uses military grade 256-bit AES encryption to encrypt all data transferred during a backup / restore operation using IDrive VMware Backup feature.

How do I restore virtual machine(s) to the VMware Server?

To restore a virtual machine(s) to the VMware Server,

  1. Login to the IDrive application and click the Restore tab.
  2. Locate and select the 'IDVMwareBackup' folder in your IDrive account.
  3. Click Restore Now to restore the 'IDVMwareBackup' folder to the local computer.

  9. Click Restore Now to restore the virtual machine(s) to the VMware server.

Is there a need for an additional/external storage volume for VMware Virtual backup?

No. However, do ensure that the temporary location that you select while scheduling the VMware Backup has sufficient disk space to hold the selected items, during the backup process.

Can I attach a VMDK file from IDrive VMware Backup to a different VMware server?

Yes, You can attach a VMDK file from IDrive VMware Backup to a different VMware Server.

Can I upload the backed up vmdk file using "vsphere client/web interface " to attach to VWware ESXi?

Yes, you can upload the backed up vmdk file to ESXi using vsphere client. However, you need to convert the monolithic sparse vmdk file to thin disk after uploading using "vmkfstools" to attach to VMware.

Run the following command to convert the monolithic sparse vmdk file:
vmkfstools - i "Source vmdk path" "destination vmdk path after conversion"
For example: vmkfstools -i /vmfs/volumes/datastore1/centos/centos.vmdk" "/vmfs/volumes/datastore1/centos/centosafterconvert.vmdk"
