Full System Backup?

[Former Member]

Hi All,

How can i take the full system backup (including OS) which is running with ECC 6.0 on Oracle 10G platform? Is it OK to take full system backup after closing Oracle and SAP services? With this can i recover the whole sytem?

Hello Vikram,

You can go for any one of the following combinations:

1) Offline backup + OS backup

2) Online backup + offline redo log files + OS backup

3) Online consistant backup + OS backup

(For Windows platform: Include windows registry in OS backup)

I guess it's sufficient to recover the whole system

Hi All,

Thanx a lot for your replying my queery!! With Full System Backup together (OS + SAP) cant i recover the system to the backup date? Bcoz i have read in one of SAP doc that we can take the backup after closing SAP and Oracle Services and i too have recovered the whole system after the installation of fresh ECC 6.0. But know the system is live now.

for live system backup you should take daily online + redolog files and weekly offline of your db backup and OS backup.

Hello Vikram,

You are only required to stop/close SAP & Oracle services for 'Offline' backup senario.

You do not have to stop SAP & Oracle for 'Online' backup senarios.

If you recover the system using ofline backup, you can open the database.

But incase you recover using online backup, you have to recover the database by applying redo log files & then open the database.

if Oracle is down, you can safely do a full Os backup of all drives. no problems.

if you cannot shutdown Oracle for backup, check online backup using brbackup.

Hi All,

Thanx again for ur valuable suggestion ..:)). Obviously i'm taking regular backup of production system (Morn Archv log + Online backup Eve + Eve Archv log). But if anything wrong with the OS in that scenario i can recover whole system together. I just want to know whether it is possible to recover this way? Also, i can follow this practice for QA server as very rare we are using it.

what is you OS? the OS backup strategy will change a bit depending on OS.

Hi Vikram,

In theory, a .tgz of <b>/oracle, /sapmnt, /usr/sap</b> and <b>/home/<sid>adm</b> and all its contents, could be sufficient. At practice, if everything was lost and you want to recover, you will have problems to run your system...

Recommended to have a good B/R policy to minimize downtime in case of disaster.
