Expected behavior if I convert MBR disk to GPT

Post by dimaslan »

We have a Veeam server at a customer, backing up a physical machine with Veeam agent.
Our team discoverered the old provider had created the large data disk using MBR, so we cannot expand it past 2.1 TB.
Our team will need to convert it to GPT using a tool but our Veeam server does not have enough space to do a new full.
Does anyone know what the expected behavior will be after the disk is changed from MBR to GPT?

Hello Dimitris,

We will process only the changed disks by creating a full backup, unmodified volumes should be processed via incremental backup. Please keep in mind that if you change the layout of the data volume while migrating MBR to GPT this would also trigger the full backup for the data disks. Thank you!
