If you try and backup all filesystems to a tarball on the local machine, you'll go into a loop (backup up the backup file).
To do this via a telnet session is a bit tricky as (I think) telnet isn't really designed for non-interactive stuff.
I recommend ssh (or rsh if you have to):
Or
(Which command to use depends on your shell, if one fails, use the other)
You can leave out the gzip bit if you wish, that's just there to reduce the size it takes up.
You could also look into using ufsdump instead of tar but that's really a matter of preference.
If you can't use ssh, you should be able to just swap the word "ssh" in the above command for "rsh" (I've used ssh's backwards compatibility flags for that reason).

Say, we are going to mount a remote file system on our server. I am not too sure about how will data be transferred back to original host when it is written to the mounted FS. Could you please share an article or your knowledge on this?
Thanks in advance;

Quick question,
is it possible to make a Tar of completely directory and placing the tar file in it (will this cause even the tar file to tarred ?)
sample:
/opt/freeware/bin/tar -cvf - /oracle | gzip > /oracle/backup.tgz
will the tar file backup.tgz also include backup.tgz ?
i tried... (5 Replies)
Coming from this thread, just wondering if there is an option to check if the Tar of the files/directory will be without any file-errors without actually making the tar.
Scenario:
Let's say you have a directory of 20GB, but you don't have the space to make Tar file at the moment, and you want... (14 Replies)

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
rized_keys file.
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary.)
NOTES
This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability disabled manu-
ally, e.g. via
chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys
on the remote machine.
