Backup During the backup of some Linux-based machines, the following error occurs: Cannot find EFI boot manager entry for EFI System Partition GUID
This issue occurs due to a change in how Veeam Agent for Linux (VAL) attempts to identify EFI boot manager files. These changes were introduced in Veeam Agent for Linux v6.3.2 to expand support for RHEL 10, which has a different EFI boot manager layout than previous versions. As part of this update, Veeam Agent now searches for EFI boot manager files in lowercase (.efi). However, on some hardware servers, the VFAT filesystem—which is case-insensitive but case-preserving—causes all EFI paths written by the firmware during boot to be automatically uppercased (e.g., \EFI\REDHAT\SHIMX64.EFI). As a result, the backup job may fail to identify these files when they are stored in all caps.
This solution section includes a section for addressing the issue during the backup restore point creation, and a section detailing how to resolve the post-restore boot failure that occurs when a restore point that had the error is used.
If issues persist, either during backup or after a Bare Metal Restore, please contact Veeam Support for assistance.
