Hi,

192.168.2.26:443

Which machine does this IP belong to?

Also please elaborate on what's the specific software that you use? Windows 10 - is it a VM included into a backup job?

Thanks

Veeam backup should automatically reset CBT data if it detects virtual disk change (shrink/increase). Does a job retry work for this VM?

[jamerson]

Thank you Vitaliy,
the VM is Win 10 and is included on the back, lately I had extended the disk .
yes the job is selected to retry for this VM.
VEEAM Version is 9 with the latest patch.
I just rebooted the VM 10 and hopefully the next update will goes fine.

Ok, also if you're replicating VM which virtual disk has been resized, please expect this behavior > VM disk size changed since last sync, deleting all restore

thank you.
i run into different issue, i need to save the disk space . so thought to use a high file compression.
i understad its takes longer than normal but would it save the disk spaces ?

[Vitaliy S.]

High compression level should provide you with additional 10% compression ratio over the Optimal level, but it will require about 10x higher CPU resources.
