Perhaps the better question is how can I make that work over ssh? I believe exporting RSH=ssh should work. Yes, indeed it does. Thanks Ted! Jeff !DSPAM:4d278f09237972063685328!

I have a learning story about how easy it is to type tar "c"zvf instead of tar "x"zvf and in a split second wipe out a huge tar backup file but I'll let you make that one for yourself. Contrast that to "dump" and "restore" and I don't care how late it is or how long you've been rebuilding a server, you are not likely to confuse the two.

Writing to remote tape
Hi, I have 2 servers that get backed up to tape. I was scping the daily dump files to the server with the tape attached but now I no longer have hard disk room to do that. So I read the man page for rdump/dump and that led me to rmt but I have been unable to make this work. It fails with a connection refused error, and I could not glean from the rmt manpage why. jr...@dukkha:/home/jross $ sudo sh -x /etc/scripts/tape_backup.sh Password: + dump -0a -f nirvana.internal:/dev/nrst0 /dev/sd0a nirvana.internal: Connection refused + exit nirvana does have pf enabled, but it uses a pass all ruleset.
