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#
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.
