Many ways to do it.

If you have space somewhere on system itself,
then

cd /sybase
find . | cpio -pxlmd /path_where_you_have_enuogh_space.
lvremove /dev/vgxx/lvolx ->sybase lvol
recreate it - lvcreate
mount it.
copy back old data.
cd /path_where_you_have_copied_data
find . | cpio -pxlmd /sybase

Thanks again!

Hi Rambo,

If you are familiar with "tar", you can use it as well.

# tar -cvf to create and # tar -xvf to extract.

Hi,

if you have tape drive then you can do a fbackup also.

Hi,

Do a "man fbackup and frecover". You will get to know how to do it. Also, check this docs,

fbackup -v -f /dev/rmt/0mn -i /sybase
frecover -xv -i /sybase -f /dev/rmt/0mn

I would use tar

Make an empty directory with at least
as much space as is on /sybase
and then transfer with tar immdiately
through a pipe , an carbon copy

Assume you have directory /backup then
the command is:

go to /sybase
cd /sybase
tar cd - . | (cd /backup; tar xvf - )

This will also inlucde 0 byte files, links
everything, thus an exact copy and you
can check the block sizes afterwards to
compare. No need to use intermediate tar files

Just the dogs bollocks !!
