Re: Way to detect if Fast CLone for ReFS is enabled

OK so for the backup jobs that I ran Active Full on, I see fast clone now.

I setup a backup copy job that has done two weekly copies, however, I am not seeing fast clone on this? Repository A is 2016 with ReFS and contains the backup files (which are created by Veeam 9.5 on ReFS 3.1), and Repository B is also 2016 with ReFS and is the target for the backup copy jobs.

What am I missing?

Again, there could only be two reasons: either Repository B itself, or some of the backup files participating in the synthetic full operation were not created by 9.5.

When should I see the [fast clone] on the Backup Copy job? It's now up to keeping 4 weeklies (which is what it is set too)?

Also, I don't see any space savings on these, they all consume the full amount. Is this correct?

Starting from the second weekly at the latest, so it is definitely not working for you.

I have another repository in a different location, that was setup from new with 9.5 and 2016 with ReFS, it's now got 4 weeklies and a monthly, I don't see any [fast clone] or space savings either.

Unless you are using active fulls with your Backup Copy jobs - I have no idea what could be the issue here, so let our support review the debug log files and tell you.

I have the option "Read the entire restore point from source backup instead of synthesizing it from increments" checked ... is this what I am not seeing space savings?

Not seeing [fast clone] though, so have opened a support ticket. #02090861

Correct, this is the reason.
