[Caesar_3]

Hello!

Using tar is fast:
tar cf - | (cd ; tar xf -)

But if you will give more information about
the copy that you intresting it maybe change
the answer.

fast?? this what we do here.I assume you trying to archive minimum down time for the database.For database cold backup,we copy the datafile to the disk.As the disk is big we used a gzip.

So the step are :

1) shutdown database.
2) copy to the disk.
3) startup database.
4) copy the disk to tape.

For a critical machine,we do :

1) shutdown database.
2) split the mirror.
3) start the database.
4) mount the split mirror.
5) backup the mirror to tape.
6) join back the mirror.
