SLP will do it for you.

If you decide to use inline copy then:

Go to catalog, select duplicate and find the backup image you want to duplicate. Select it and right click on it.  Select duplicate

SLP will guarantee that the subsequent copies get completed before expiring the original backup image (copy 1). With normal duplication or inline tape copies, you don't get this level of protection. Once the initial backup is completed, the impact of duplication is on the media server, not the client.

Re: [Veritas-bu] Multiple copies option in Netbackup

 




Hello,
1.        both backup copies will start in parallel.
2.        Automatically, only with SLP. But you can manual duplicate the backup.
3.        SLP is better. Even if you do only dual copy backups and no duplications, if a copy fail, SLP will create it  by duplicating from the succeeded copy.

Both ways, SLP and inline copy, are working the same way. They read the data ones and write the data to two locations at the same time. The speed of the backup is the speed of the slower device + a small overhead.

[Veritas-bu] Multiple copies option in Netbackup
 
Hello Geeks ,
 
 
Good Day !!
 
I have few questions in mind about the multiple copies option in Netbackuo
 
 
1) Does both copies start parallely ?
2) How can one start the copy 2 if it fails after successful copy 1 ?
3) WHat is better SLP or Multiple copies  ?
 
I guess SLP uses the image already made to duplicate but multiple copies is just like backup so putting double load on client and backup windows will also increase ?
 
 
 
Please clear me on this.
 
 
Thanks ,
Pranav
