Making backup with ufsdump to remote mounted filesystems

Hi Unix members.

I am trying to make a backup to remote mounted filesystems :

fileraseing:/vol/oracliente_revap01
10G 1.3G 8.7G 13% /orarev_ap01
fileraseing:/vol/bobje 
10G 5.9G 4.1G 60% /bobje

But I am receiving the follow message when use the ufsdump command:

[\u@\h]:$PWD>ufsdump 0fu /dev/rmt/0n /orarev_ap01
DUMP: `/orarev_ap01' is not on a locally mounted filesystem
DUMP: The ENTIRE dump is aborted.

I think that I cant do backups on remote resources using ufsdump....

But that can I do for resolve to get the backup using tape resources on remote filesystems?

Could someone help me ?

Thanks in Advanced

Use something not filesystem specific, like tar, cpio, pax, star or whatever.

To perform remote backups across the network,the system with tape drive must have a entry in its ./rhosts file ....
syntax:#ufsdump 0uf hostname:/dev/rmt/0 backupfilename

That's not the OP issue. Ufsdump, as its name suggests, is designed to dump UFS filesystems, not NFS or whatever ones.

Not true. ufsdump can be done this way. NFS mount your target host onto the system that you are backing and run it. It WILL work. I have done it several times. Maybe some big diff in NFS versions?

Of course you can, but the open poster is trying to backup a remote directory.

Hi

Your code is correct
ufsdump 0fu /dev/rmt/0n /orarev_ap01

please try as

ufsdump 0fu /dev/rmt/0n <file systemname> (actuall name used to mount)

Example:
ufsdump 0fu /dev/rmt/0n /
ufsdump 0fu /dev/rmt0n /var

we are taking backup the same way and working fine. You can search some script also available.

Thank you

Once again, the open poster issue is misunderstood ...
It would probably have helped if the thread title had been correctly phrased "Making backup from remote mounted filesystem".

Is there anything about remote backup in your post?
