rdist, rsync or something else?

[kgraff]

Hi

I need to copy everything, about 250Gb, from one LV to another LV on the same host. Most of the files are Oracle dbfiles.
I could use tar in a nifty way, but that would require Oracle to be shutdown for quit a long time, and that's not very appealing.
From the manual I gather, using rdist would be pretty much the same. But what about rsync? Or is there another way I don't know of? Windows-guys have Robocopy, and that would have been nice, but there's no such for Unix, right?

Hi,

Rsync is very good to synchronise directory, backuping them to another location etc.

Shalom,

Choices:

dd if=/source of=/dest

scp -rp source destination

rsync can do it as well.

The oracle databases must be shut down to get clean copies.

Steven,

Would it have to be shutdown even if I run rsync as a daemon?

I allways recomend rsync, it's a great tool.

you can download it from:

I have attached a file with a quick guide for several command tools for copying data.

Hi,
Stop the database before doing rsync even in daemon mode.

Using the raw device always improves performance with copy.

#dd if=/dev/vg00/rlvol11 of=/dev/vg00/rlvol13 bs=1024k

Once copy is complete, use fsck before you mount the vol.

Is copying your data base files while they're
open and changing _more_ appealing?

cpio, "pax", rdist, rsync, "tar", whatever,
who cares? I don't see how you can expect to
copy any files which are in use, and then
expect the results to have much value, no
matter how you do the copying.

Well, my question really was if there are such a way, like Robocopy, not wether you care which tool I use. But thank you very much for sharing your opinion.
