VMware Tools Version Status: 3rd-party/Independent
VM Version: 4
CPU: 4
Memory: 8192
Provisioned Storage: 218.09

Re: CBT not used during replication
Hi,
Why do you think that it can't use CBT? Did any errror messages appear during replication?
Thank you

Re: CBT not used during replication
Hi PTide,
The reason i'm saying that its not using CBT it because the replication session does not show CBT, it reads the entire drive and replication is taking longer. No error message.

Please double-check the following:session does not show CBT, it reads the entire drive and replication is taking longer. No error message.
- CBT is enabled in replication job settings
- The replicated VM has no existing snapshots
- The replicated VM is a Veeam Backup Proxy
- You see nothing like
Code: Select all
Hard disk 1 (50.0 GB) 16.1 GB read at 15 MB/s [CBT]

Re: CBT not used during replication
I have one job that has a couple of VMs replicating using CBT but its only one particular VM that is not using CBT.
So,
- Yes, CBT is enabled in the replication job settings
- There is no exisiting snapshots for this particular VM
- Replicated VM is not a Veeam Backup Proxy (not why you are saying replicated VM is Veeam Backup Proxy?)
- I don't see that in the session logs

Re: CBT not used during replication
Could this be related to the VM running with VM Version 4? What is supported VM Version in order to use CBT

It's 7What is supported VM Version in order to use CBT
For some reason I thought that you were using hot-add mode (CBT is disabled for backup proxies servers using hot add processing mode), sorry about that.not why you are saying replicated VM is Veeam Backup Proxy?
Thank you.

Re: CBT not used during replication
Thanks PTide,
One more clarification, on Veeam site they talk of VM being backed up must be at least hardware version 7. Is hardware version mentioned by Veeam mean the same as VM Version mentioned by VMware?
