we have been moving VMs from one host to another (No vCenter in use) for a few weeks. For this we use the possibility in Veeam via replication with following failover and final permanent failover. Now we see in the Veeam console under Disk (imported) several jobs with a restorepoint where the timestamp matches the migration time. However, the name of the backup does not match the regularly created backups either (See screenshot). However, not all migrated VMs are present here in the list. There must be some differences in the way we perform the migration what creates in some circumstances this backup file.
Does anyone know how this imported disk is created and can I safely delete it? How to proceed so that this is not created in the first place?

Thx & Bye Tom
