fastest copy from one to another server

Ignacio Rodríguez Arrós — Thu, 27 Nov 2003 09:14:34 GMT

I have a new rp 5420 with hpux 11 and i want to copy some directories with their subdir from one d280 with hpux 10.20. Ican,t do it with tapes because the d280 has a dlt, and the rp has an ultrium unit, so iÂ´m doing it with a client ftp in a pc, but it is too slow. Â¿what command can i use to copy directly from one server to the other? Both servers are in the same

Hi Ignacio,

In the hpux 10.20 server, cd to the directory whose contents you wan to copy:

#tar cvpf - . | remsh <11.0 IP address> -l root "cd ;tar vxpf -"

Hope this helps.

Hi,

one suggestion more:

fbackup -i /src -f - | remsh remote -l root(cd /dst; frecover -Xrf -)

greetings,

Michael

Oops,

something missing:

fbackup -i /src -f - | remsh remote -l root "(cd /dst; frecover -Xrf -)"

greetings,

Michael

The fastest way I found was to tar/gzip them up, then rcp them to the new server.

If on the same subnet, then mount the remote dir via NFS and use vxdump:

vxdump -0 -f - -s 1000000 -b 16 /some/dir | (cd /mnt/some/dir/on/new/server ; vxrestore rf -)

Hi,

an alternative would be:

rcp -pr /src remote:/dst/

thats also quite fast.

If i use rcp what may i do in the remoste host to permit to write in it from the local server (the remote server denied access from local if i donÂ´t log like a remote use

Hi,

you would have to create a .rhosts file with access 600 on the remote host and add the local host and user, you want to allow access. Then use rcp -pr /src userremote@remote:/dst/
The userremote, in case the local and remote user are not the same.

Michael

Hi,

I forgot to say, that .rhosts must be in the home directory of the remote host.
Example of a line in .rhosts:
d280-hostname user-on-d280

greetings,

Michael

Hi
Are you overwriting the destination directory with almost similiar data from the source? Check out Remote Sync for HP (rsync)

http://rsync.samba.org

Its the best for daily backup
