Hi, we have an HP Surestore dlt vs80e and use hp dlt IV tapes (capacity 40/80GB) under linux. But the backup is to slow, we should have a backup rate of 10.8 GB (native)/20.6 (comprimized), but we do not have :-( So i have some questions, to which i did not find answers until now!
In the file tapelist we have following entry (i dont know why): ------------------------------------------------- define tapetype HP-DLT { comment "HP SureStore DLT" length 80 gbytes # conservative estimate filemark 1 byte # should work given above speed 30 mbytes # even more, but this isn't used in amanda } ------------------------------------------------- length in comprimized (80) or uncommprimized (40) modus? What does filemark mean? speed in mbytes per minutes or ...? Does it have any consequence if i insert to much/less speed? How can i activate software or hardware compression (cant find an entry in amanda.conf, just Client or Servers best in dumptypes-file)? I have differnt directories to backup, and i want to pack them in _one_ big package, so i specify a chunk size of 20GB, but Amanda creates for each entry in the disklist one package/file. A hardware question: If i have many packages to flush out to tape, are they written at once so that the tape comes into the streaming mode or does the tape have to be stopped and restartet for each package newly? What happens if i delete some files in the holding disk manually? Does it have consequences and the database is corrupted? What does "ignoring cruft file" as log message? I would be happy if someone can help me! Maybe someone has the same configuration! Thx a lot, Dalton
