Bug Description
We are unable to take backups of Generation 2 VMs because they include a FAT 32 EFI partition. This patch ignores such partitions while freezing the file-system to take a snapshot during the initial stages of the backup process. Since EFI partition is not expected to be modified regularly, the ignore functionality should address the problem. Please include the following upstream patch in the vss daemon:
Tools: hv: vssdaemon: Ignore VFAT mounts during the Freeze operation
If the guest has a FAT file system mounted, skip it during the FREEZE
operation. With this change we can support host initiated backup of
the guest even when the guest may have FAT file systems mounted.
Thanks,
Abhishek
