Hi all, Thanks very much for the replies. It didn't occur to me to check hardware compression.
One comment to make, though - I am using a holding disk, and currently it's free space is greater than the amount of data being backed up, so does this log look like something's going screwy there too?

No, you're not reading this right. 5 Gbyte of dumps for 4 DLE's were successfully written to tape. While writing the fifth DLE, amanda hit EOT at 16875296 Kbyte (or about 16 Gbyte). A few comments. The report says: > olympic /samba/company lev 0 FAILED [dump to tape failed] That means that you were not using a holdingdisk for this DLE. Maybe it's too small? It helps a lot in having a large holdingdisk. Unless you have really fast hardware and network, the tapedrive must constantly stop/rewind-a-little/restart again. Besides the fact that this slows down the whole process enormously, this is also a fast and proven way to wear the tapedrive in a few weeks! > tapetype HP-DDS-4 > > define tapetype HP-DDS-4 { > comment "just produced by tapetype prog (hardware compression on)" > length 17021 mbytes > filemark 403 kbytes > speed 1578 kps > } You seem to be using hardware + software compression at the same time. This is a waste of tapecapacity, and a wast of time, and a wast of cpu. Put your tapedrive in hardware compression off, and you'll gain almost 4 Gbyte in capacity! > I'm wondering about a faulty tape drive or tapes? If you keep bypassing the holdingdisk, that answer will be "yes" in a few weeks. But currently is it "no". >>olympic /home 0 90793005319769 58.6 69:241277.4 69:251277.4 This reads much clearer if you add some whitespace between the columns. Search the man page about "columnspec".
