You cannot import transaction log backups without VM backups (as there will be no restore point to which the transaction logs can be applied).
To import a VM backup with transaction log backups, do either of the following:
- Import a backup metadata file (VBM). In this case, Veeam Backup & Replication will automatically import the database backup and log backups.
- Import a full backup file (VBK). In this case, Veeam Backup & Replication will browse to corresponding log backups and import them, too.
