blocksize. The default for tar (10k) is pretty small for modern tape drives. Try -b 128 (for a 64k block size). Another optimization would be to put a buffering program in between tar and your tape drive to decouple disk reads from tape writes. misc/team, misc/buffer, and misc/cstream

, I'm certain that there is no recursion going on. The delays are happening too early on for that. Also, this script works well if I target an external HD but never finishes on the tape. Thanks for the idea. I hadn't considered it before. Jaime

I am trying to replace an older DLT tape drive (which doesn't like to eject tapes any more) with a new Quantum DLT-4 drive. Its connected by internal SCSI and seems to be set up right. But after DAYS of running a tar command, its still not done backing up 60GB. The old drive could backup 70

misc/buffer, and misc/cstream in ports are good for this. Thanks. Would this decrease the ability of other Unixes being able to read the tape? For example, using pax (which can read tar archives) or GNU's tar? no just use -b in other unices too :) When reading from the tape using tar

. Also, the same command in Knoppix (Linux) using /dev/st0 (the Linux equivalent of /dev/sa0) appeared to write to the tape and then list the items on that tape. I didn't see how long it would take, though. In retrospect, maybe I should have let that run longer. :( How certain are you
