Hello >From "man dump": -a ``auto-size''. Bypass all tape length considerations, and enforce writing until an end-of-media indication is returned. This fits best for most modern tape drives. Use of this option is particu- larly recommended when appending to an existing tape, or using a tape drive with hardware compression (where you can never be sure about the compression ratio). I have Sony DDS DG90M (90m/295feet) data carttridge and: (ncr0:6:0): "ARCHIVE Python 28388-XXX 5.45" type 1 removable SCSI 2 st0(ncr0:6:0): Sequential-Access st0(ncr0:6:0): 6.7 MB/s (150 ns, offset 8) density code 0x13, drive empty Do I have "modern tape driver" or not? :-) # mt rewind # printenv TAPE /dev/tape # ls -la /dev/tape lrwxrwxrwx 1 root wheel 5 Apr 15 1997 /dev/tape -> nrst0 # dump -0au /u [...] DUMP: 63.53% done, finished in 0:37 DUMP: 68.49% done, finished in 0:32 DUMP: 74.53% done, finished in 0:25 DUMP: 79.67% done, finished in 0:20 DUMP: 82.92% done, finished in 0:17 DUMP: write error 1773020 blocks into volume 1 DUMP: Do you want to restart?: ("yes" or "no") no DUMP: "Yes" or "No"?
