Solaris 7 newbie tape backup question

Hello all,

I have an ss20 running Solaris 7, with an attached 4mm tape drive. The machine has one 1.2GB SCSI HDD. I would like to backup other machines
to tape, but I can't do a stopover on the ss20s hard disk, as there is virtually no space available. Is there a way I can make the tape drive available over the network, so I don't have to write archives to the local hard disk, then to tape, but directly to tape?

I hope this is clear enough; thanks in advance.

Let's say the hostname of your ss20 is server1 and the tape device is 0.

To backup all /opt files from server2 use server1:/dev/rmt/0n
# hostname
server2
# ufsdump 0cf server:/dev/rmt/0n /opt

See the man page for ufsdump (and/or tar) - a .rhosts file will be needed (I usually had one created via the scripts I ran just before the dump and then delete them afterwards as it is a security concern) along with the IP and host names in /etc/hosts for each server involved.

Nice! Thank you so much for the advice. I'll try it when I have a chance.

How about content format of .rhosts file, is it same as /etc/hosts.equiv:
hostname user

Thanks

Yes, or you could use hosts.equiv

All that is required is rsh/rlogin works without a password.

Thanks,

What I want is backup data from local machine to remote which have tape driver with root account. As I read, we need to have local hostname in .rhosts of remote machine for this task. I created .rhosts file.
