The dump/restore routines have a built-in rsh handler for execution on other boxes, and rsh knows how to interpret DEV:. The mt program does not, so that the DEV: syntax means nothing to it.
For those with backup tapes (and I just bought and installed a Seagate one for my FreeBSD box) I want to know how to get the most out of each tape by placing multiple backups on each tape (potentially 20GB). Please correct me if I'm wrong:
First, retension the tape:
# mt retension
next, turn... (3 Replies)
Currently am running the backup command for AIX 5L and see that the tape is rewinding after the completion of the back.
backup -0 -u -f /dev/rmt0 / >> $file 2>&1
What can I do to stop allow the backup to rew after the completion of this job? Any thoughts?
Thanks again. (2 Replies)

Hi, I am currently looking at how we can optimize and speed up our backups here. I am just a beginner operator and our system admin hardly knows anything (long term interim).
There is this particular TAR backup of DB backups that for a 10.5Gb amount of files, it takes 5 hours to do the backup on... (6 Replies)
It may seam a bit odd that I ask this question.
After you have done your backups to tapes, do you verify the content of the tapes ?
- never
- sometimes
- always
The reason I am asking is that here in the office, all the backup procedures include verifying the content of the tapes (no... (5 Replies)
Hello all. UNIX dummy here :p
Anyway I was trying to do a full backup of my work server SUN SPARC SERVER 1000 machine (yes we are actually using this dinosaur). I did the ufsdump comand and everything was fine until I got to the dumping of regular files. During the run I got the following... (7 Replies)
Hello folks. I have the following problem:
I'm trying to create a tape backup of a list of files on a 10 year old server, running SCO Openserver 5.0.5 (the tape drive is a Seagate STD224000N, connected as a SCSI drive).
I then want to restore the contents of this tape onto a new server... (6 Replies)
Hello,
I need to be able to encrypt LTO tapes that our AIX writes to for backups.
We have a tape library (IBM TS3100) that our AIX host uses to write to LTO6 tapes. We then take those tapes off-site and restore to another AIX system using a 3580-H6S LTO6 tape drive - this is a very simple... (3 Replies)

rsh
RSH(1) BSD General Commands Manual RSH(1)NAME
rsh -- remote shell
SYNOPSIS
rsh [-Kdnx] [-k realm] [-l username] host [command]
DESCRIPTION
Rsh executes command on host.
Rsh copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error
of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh normally termi-
nates when the remote command does. The options are as follows:
-K The -K option turns off all Kerberos authentication.
-d The -d option turns on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the remote host.
-k The -k option causes rsh to obtain tickets for the remote host in realm instead of the remote host's realm as determined by
krb_realmofhost(3).
-l By default, the remote username is the same as the local username. The -l option allows the remote name to be specified. Kerberos
authentication is used, and authorization is determined as in rlogin(1).
-n The -n option redirects input from the special device /dev/null (see the BUGS section of this manual page).
-x The -x option turns on DES encryption for all data exchange. This may introduce a significant delay in response time.
If no command is specified, you will be logged in on the remote host using rlogin(1).
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote
machine. For example, the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the local file localfile, while
rsh otherhost cat remotefile ">>" other_remotefile
appends remotefile to other_remotefile.
FILES
/etc/hosts
SEE ALSO rlogin(1), kerberos(3), krb_sendauth(3), krb_realmofhost(3)HISTORY
The rsh command appeared in 4.2BSD.
BUGS
If you are using csh(1) and put a rsh in the background without redirecting its input away from the terminal, it will block even if no reads
are posted by the remote command. If no input is desired you should redirect the input of rsh to /dev/null using the -n option.
You cannot run an interactive command (like rogue(6) or vi(1)) using rsh; use rlogin(1) instead.
Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here.
