Hi,

Going by the nature of your requirment ( copying prduction ) , homogenous system copy using Backup Restore should be the best option. The SAP system copy guide should be good enough for you as a guide.

Dear Amit,

If you are going to use same System(32/64 bit), same OS, same DB. You can use backup and restoration.

For 800 GB, you required only 4 - 6 hours downtime. In the while, you can start fresh installation.

That will save your Time and reduce Downtime.

For System copy, the downtime will be more.

If there is ant change in the System wise or OS wise or DB wise, System copy is recommended.

Otherwise, Backup and restoration itself sufficient with less downtime.

With regards,

Hi Amit,

I would prefer you do a Homogenous system copy... do a backup and restore during the installation itself.

This will save you lot of time.

Based on the SAP release and DB that you have, look for a system copy guide in the service market place.
