Dear All,

Thrice in need to copy my files ( 5 folders of different sizes) of 80 GB, to different disks in the same machine. or in the remote linux machine in the network..

am using cp command for local copy. and scp for remote copy .. but this takes morethan 7 hours even though I start 5 concurrent sessions for five folders.

can anyone advise me any fastest way to copy and full copy as we are doin this as backup of our production environment.

Thanks in Advance
Yusuf

If each day there are only small changes, even though the total size of data is very large, you might want to consider using rsync. rsync works out which parts of files have changed, and only sends those parts necessary to make the destination match the source.

Yusuf, while what matthew said certainly holds true, the transfer
speed seems somewhat slow ... a rough calculation based on the
figures suggests a speeds of ~ 3.2 Mb/s ... what kind of media are
you using, what is the physical limitation of the hardware?

What kind of hardware are you running this on?

Cheers,
Tink
