Restore Solaris UsingNetBackup BMR

Here we are going to restore a Solaris client using NetBackup Bare MetalRestore. Before we are able to do that we have to enable this option inthe NetBackup policy for the client:

When the backup was done successfully youre ready for a NetBackupBare Metal Restore.

Considerations

Bare Metal Restore Infrastructure

When perfor!ing a Bare Metal Restore youll have to keep a few thingsin !ind. "riginally a bare !etal restore is intended to restore to theoriginal !achine for! which the backup was taken. However# in our

environ!ent we use the Bare Metal Restore to restore the productionenviron!ent to our acceptance environ!ent for $ontinuity %lanningreasons. &hat !eans that the original server is still online when therestore takes place.

Network Conguration

&he Solaris environ!ent were restoring is 'nstall Solaris () *pdate +#and as e,plained in that article that edition of Solaris does not havenative support for the -MN/&0 network adapter. &hat card is howeversupported after installing the -Mware &ools. &hat !eans that the backupwe !ade is for a -MN/&0 card# which we cannot use because the boot

!edia uses the native solaris installation !edia. Re!e!ber to createthe -M to restore to with an e())) network adapter and con1gure thenetwork after reboot accordingly.

DNS

NetBackup is heavily dependent on a working 2NS environ!ent. 3ouM*S& change the host1le on all NetBackup servers that have a role inthis Bare Metal Restore action. 'n our environ!ent that is:

• bck!aster)(b

• bck!aster)(a

• bck!edia)( 4!edia server appliance5

• bck!edia)6 4!edia server appliance5

Running the Restore

Because the -M were going to restore to is not the original -M thehardware were going to restore is never the sa!e# plus that we have toconsider the changed network card. &hat !eans well 1rst have to getthe new hardware con1guration into NetBackup. /asiest way is to start adiscovery on the server and than use that discovered hardware to createa new pro1le to restore with.

So# as a overview# these are the steps:

(. $reate a discovery task of the client

6. Start the client so hardware discovery can take place
