tar to tape drive command
I want to use this command to tar to tape:
Code:
tar cf - DIR | compress > `hostname`_`date +%m-%d-%y`.DIR.tar.Z

this of course goes to the FS.

How do I modify this to go directly to tape?

My tape device is /dev/rmt/0

thanks.

I'll also suggest, provided your tar supports it, adding either -z (gzip) or -Z (compress) to have tar do the compression as it writes.


Code:
tar cvf /dev/rmt/0 -z DIR

find . . . -type f | cpio -oaH crc | gzip -9 | dd (help me here).

Tar used to pad files to block size with nulls, wasted media. Luckily, cpio does not, and this gives you complete control over the compression, and multiprocessing.

What do you do when the tape does not read, which old tape is prone to. I thought everyone had gone dvd and network by now.

IMHO (Hope Im wrong...)I doubt you can give a name+extension AND sent to tape all in one...
Either you create a file you copy after to tape...
or
You pipe to tape (but cannot choose to give a name...)
Code:
tar cf - DIR | compress | dd of=/dev/rmt/0
