Help with "Changed block tracking map was changed for volume" message...

[Backup_Guy]

From time to time I get this message in Veeam when I double click a job that is showing a warning "Changed block tracking map was changed for volume ..." however I'm not sure how to interpret it. Anybody have any ideas on this?

Thanks...

What platform are you talking about? In other words, what are you backing up, and with what type of a backup job? We will move this topic into the correct sub-forum once you respond. Thanks!

It is a Windows 2016 physical server being backed up by a Veeam agent. What I read about this is that the disk layout has changed but in checking I don't see that is the case...

Do you have resized your disk partition?
If yes, this will change disk layout and reset cbt map

[Andy.Woodhead]

Does any action need taking here or will the next run pass OK? Does something need to happen in the OS / In the Backup Console to make this pass as "success" rather that "warning" please?

You don't need to do anything. At the next run of the backup job, CBT can be used again for all backups.
Until you resize a disk again, of course.

Resizing a disk will always led to resetting the CBT information.
On the Veeam Agent, on a VM.

Hi folks,

Since no user interaction is required info severity makes more sense, I'll discuss it with RnD folks. Thank you!
