How to speed up cloning

Usually during clones, we normally tar & gzip source files. Then copy them over to the target and then gunzip & untar it. Using the below method, we can actually avoid the two fold step and do the entire operation in a single step.

eg.
We want to copy the Oracle Home from source to target.

Create the Oracle Home location on target (lxhyd02):
mkdir -p /data/oracle/product/10.2.0/db_1

On the source (lxhyd01):
cd /u01/oracle/product/10.2.0/db_1
tar cf - * | ssh lxhyd02.learning.com '(cd /data/oracle/product/10.2.0/db_1/; tar xf - )'

Check if files are being untarred on target:

[oracle@lxhyd02 data]$ cd /data/oracle/product/10.2.0/db_1
[oracle@lxhyd02 db_1]$ ls -tlr
total 240

Advantages:

1) Faster that the two folds approach
2) Does not require disk space to store the tar/gzip files on source and target. Here, the tar files are created on the fly and immediately untarred on the target.

Limitations:

1) Speed would depend on the network bandwidth.
