Definitely, Veeam fails on reading backup file:
[21.10.2016 20:14:50] <19> Error Failed to restore volume
[21.10.2016 20:14:50] <19> Error Invoke failed. Command: 'DataTransfer.SyncDisk', .
21.10.2016 20:14:50] <19> Error Failed to decompress LZ4 block: Incorrect decompression result or length (result: '-1002082', expected length: '1048576'). (Veeam.Backup.Common.CCppComponentException)
LZ4 error means that one of the backup file's blocks is corrupted (physically) and CRC sum is wrong. By default Veeam stops a restore procedure, because this failed block can contain system files and skipping them will cause a restored OS fail to boot.
Unfortunately from a Recovery Media right now it is not possible to skip bad blocks from a backup file.
However, as a workaround, it might be possible to open a backup file using VBR. VBR has specialized agents, which can skip faulty backup block and read only consistent ones. It's worth trying.
It failed around 30% due to CRC mismatch and failed to decompress LZ4 block.
