Arkeia Backup - Issue with restoration

Hello,

I am testing the Arkeia Network Product 8.2. I am using it as a VMWare Virtual Appliance. The appliance has a VTL attached and I am doing some tests backup.

I have created a Savepack with the option CBT (Change Block Tracking) selected and the transport mode as NBD.

The problem is that after the backup is made and I try to restore, its restoring the disk as Thin but its not only restoring the used blocks, but all the blocks to the VM.

While looking at logs, it doesnt say that disk is not available for CBT. I have contacted support but they are not sure what it could be.

Here is the logs of that backup,

I've never heard of or used that product before, but that is what I would expect for a full system restore.  Were you just trying to do a file level restore?
DavidPresidentCommented:
This is a situation where you should just contact the vendor, instead of EE.  I would think that since you are evaluating a product, then they would like to sell it to you.  As such, I am sure they would be happy to assist.  They are certainly going to have access to information like bug reports and configuration constraints that only the manufacturer has access to.  

There are times when the "best" answer comes from the software vendor themselves.  This is one of them.
Gerald ConnollyCommented:
The log doesnt mention CBT just that it is doing a Full backup.

This bit from the Arkeia manual shows the options

Supported Backup Types

Image Level Full Backups
Arkeia supports a Full Image level backup of all Virtual Machines when the backup type is set to Total or Archive. During a Total or Archive full backup, Arkeia will backup and restore the entire Virtual Machine image.
If your VM Image has 100 GB allocated but the used blocks are only 20 GB, a Full Image level backup will backup and restore the entire 100 GB VM allocated image.
Image Level Thin-Full Backups (CBT)
Arkeia supports Thin-Full Image level backups of all Virtual Machines when the backup type is set to Total or Archive and when the CBT (Change Block Tracking) option is set. During a Thin-Full backup, Arkeia will only backup and restore ONLY the used blocks within the Image.
If your VM Image has 100 GB allocated but the used blocks are only 20 GB, a Thin-Full Image level backup will ONLY backup and restore the used blocks and not the entire VM Image.
CBT Thin-Full backups are supported on ESX 4 and the Virtual Machine's Hardware Version 7.
Image Level Differential Backups (CBT)
Arkeia supports Differential Image level backups of all Virtual Machines when the backup type is set to Differential and when the CBT (Change Block Tracking) option is set. During an Differential backup, Arkeia will only backup the changed blocks that have occurred since the last Total backup.
CBT Differential backups are supported on ESX 4 and the Virtual Machine's Hardware Version 7.
Image Level Incremental Backups (CBT)
Arkeia supports Incremental Image level backups of all Virtual Machines when the backup type is set to Incremental and when the CBT (Change Block Tracking) option is set. During an Incremental backup, Arkeia will only backup the changed blocks since the last backup which can be a Total, Differential or Incremental.
CBT Incremental backups are supported on ESX 4 and the Virtual Machine's Hardware Version 7.
