Hi all,
I would like to backup an NFS system (from a Network Appliances filer) to a local tape drive (with multi-volume), via Solaris 8 system, which command is better ?
I have try to make this backup with ufsdump, but I have error : root@server:/tmp# ufsdump 0uf /dev/rmt/0cn /mnt/filer/ DUMP: `/mnt/filer' is not on a locally mounted filesystem DUMP: The ENTIRE dump is aborted. root@server:/tmp#
Thanks, Laurent
What version of unix is the backup client? I can tell you that Solaris 2.7 (my admin host) *will* "ufsdump" an nfs mounted FS.
It used to be back in the SunOS days that "dump" would not. I remember trying.
Can you use a Solaris 2.7+ client to try it on?

I think the reason that Sun changed the name from "dump" (in SunOS 4.x) to "ufsdump" (in Solaris 2 and later) was to emphasize that it only dumps (local) UFS filing systems!
You can use the "dump" command on the filer, possibly via rsh/ssh from the client, e.g.
rsh [filer] \ dump 0uf [client-user]@[client-host]:[client-tapedevice] /vol/vol0
ONTAP supports this use of remote (to it) tape devices, accessed via the "rmt" protocol. You must set things up so that the "root" on the filer can rsh to account [client-user] on [client-host] (via .rhosts file on the client) and that [client-user] has permission to write to the [client-tapedevice] there.
([client-user] defaults to "root" if you omit the "[client-user]@" part of the -f argument, but there's usually no good reason to give the filer access to root privilege on the client.)
Bear in mind that dumping across the network can eat a lot of bandwidth.

My apologies for my dumb statement. Yes we run (well actually used to, we've since purchased an NDMP license to support Filer attached tape drives) NFS backups on our Solaris 2.7 Admin Host but via Legato Networker.
Legato is running a proprietary client to send a stream of data to the Storage Host containing the tape drive. It simply takes a "pathname" as criteria to the path to backup and does not care if its an NFS mount.
It is most certainly not ufsdump.
My apologies for my mistatement.

Thank you to all person who answered to me. I will test the dump command from the filer tomorrow.
