hi,

i think it is better to tar the folder ,ftp the tar file to remote host,untar it.

regds,

Is it a one time job ?

# find /dir | cpio -o | remsh server " cd /copy ; cpio -idum "

90 GB is large, a tar to tape and a restore from tape could even be faster.

Robert-Jan

90 Gb is massive, not something you would ever transfer over a network with a simple copy. Unless you have gigabit LAN connections between the two machines, it will take many, many hours (5 hours on a 100Mbit LAN). ftp in HP-UX does not have the error message "not plain text" so you need to explain how you are using ftp (command line? some special GUI interface? remote system is not HP-UX?).

As mentioned, 90Gb will be transferred much faster using a tape unless the remote machine is in another city.

Hi,
as suggested use a tape backup.
May be workwhile compressing the data beforehand to cut down on the number of tapes.

You will have to archive it with either tar or fbackup...after that, ftp the archive (or rcp)...

Where is remote host? if WAN - then that will take a long time...

thanks for all,

this situation is that we want to upgrade application and we must to backup for application and database.one server for application and the other for database.backup is for rollback if upgrade is failed.so we make two backup, one on tape and the other on disk (copy disk to disk).remote host in same lan but different subnet.please give me some command that can help me!!

I recommend you use rcp. these are steps:
on server you want to copy to:
#login as user who want to copy.
#vi ~.rhost
user IP of server you copy from.
#rcp IPserver:/path/file /path/file_onlocal.

I normally use the folllowing method

source node :-

cd $DIR;tar cvf - .|remsh "(cd $DIR;tar xvf -)"

Regds,

when i run rpc ip_addressremote:/sourdir /dest_dir, there is an error rpc not registered. ????

[PiyuT]

dear all,

i use exportfs.
in server that directory will be backup(ip=10.10.x.x), i am add directory name in /etc/exports:
#vi /etc/exports
/apps11i -anon=0
#exportfs -a
#exportfs

than in remote host:
#mount -F nfs 10.10.x.x:/apps11i /data/apps11i

is it true ???is backup is success??

[V. Nyga]

NO!

You only 'see' the datas!

You still should create a tar-file, compress it (gzip) and copy it to the remote host. Only thing - you don't need rcp or ftp now.

Well - with NFS - you can just copy from the NFS mounted file system to the new one:

vxdump -0 -f - -s 1000000 -b 16 /data/apps11i | (cd /newmountpoint ; vxrestore rf -) &

That should work - will be a bit slow as you are using NFS... /newmountpoint is the location of the new filesystem for your data.

[Stephen Keane]

Be careful

rcp = remote copy
rpc = repote procedure call

You needed rcp, the error you posted is from rpc.

[PiyuT]

i'm sorry,

that i know, vxdump is to dump in tape.i want to copy to disk in another host in same LAN(same building & floor) and to onother LAN (different building).there are many another application that run when i want to copy.i'm afraid, when i'm copy data,will be need more bandwith and cause the other application will run more slowly.help me please!!

Hi Piyut
Ftp said "not plain text" it means you folder contain binary file. In you putting (or getting) scipt you must set binary mode for this file by issue bin command
ftp> bin.
and then excute you download or up load command.

Piyu, the cpio command (above in another message) using remsh will do the trick for you. However, it *will* load up your network and probably slow down other users. Well, if you can't do that - you've got just two alternatives that I can think of ...
a) build a LAN just for administration (VLAN if you will) that won't impact the other network users. That is, separate networking hardware, cards, etc. that you can use to sling stuff around and not hurt production performance.
b) Use Tape.
