Velero Kopia backup timeout on sparse files

Hello everyone,
I need some help with using Velero to backup a Kubernetes namespace. I am using Data Mover to export a snapshot to an external S3 storage. However, during the backup process, the copying of the Kudu volume(maybe 50000 files and 30GB) times out after a few hours. Can anyone help me understand why this is happening and how I can resolve this issue?
It should be noted that Kudu uses sparse files.
Velero 1.12.2
CSI driver vsphere 3.0.1
Kubernetes v1.26.6+rke2r1
Kudu 1.16
Thank you in advance!
