Summary :
Users of SAP MaxDB version 7.7 experiencing issues with backups and recoveries via tape drives may encounter errors like "hostfile_error" and "wrong_hostfile". These impediments prevent the successful execution of operations and render prior backups unusable for recovery if created with SAP MaxDB versions below 7.7. The fault specifically arises with connections to tape drives in UNIX or LINUX server environments, without third-party backup tools interference. Resolution involves updating to later patch levels of MaxDB (7.7.04, 7.7.06, 7.7.07, 7.8.01) or modifying backup strategy to use file system or pipe templates as temporary alternatives.
