then what will happen to that copy 1 which is offsited

Hi,

I have a copy 1 ,copy 2,copy 3.

copy 1 is offsite and copy 2 is onsite.

i have to initiate a restore.

i have made copy 2 as copy 1.

then what will  happen to that copy 1 which is offsited?

No, you have not made copy 2 into copy 1. You have made it PRIMARY. Copy 1 is still copy 1 and copy 2 is still copy 2.

[NIKHIL234656595]

so copy 2 is now primary.so what will happen to the copy 1 which was primary earlier?

[Marianne]

NOTHING will happen to it. It is still available until it expires.

If you want to restore from it, make it primary, or specify '-copy 1' if you want to use bprestore from cmd.

..to add to Mariannes excellent posts ...

There is nothing special about multiple copies - they are simply that, another copy of the 'same' data.

One of the copies is the 'Primary' copy - all this means is that this is the coy NBU will try and use if you run a restore.

That is it, just because a copy is , or is not, primary doesn't change anything ...

I think Marianne has correctly answered your question - perhpas you could mark her post as the solution ?

so now we have 2 primary copies ..one onsite and one offsite?

You need to read the answers we give carefully ...

From my post ...

"ONE of the copies is the 'Primary' copy  ... "

From the definition I gave ....

"...  this means is that this is the copy NBU will try and use if you run a restore."

Therefore, by definition, there CANNOT be two primary copies.

I think this question is answered, please mark one of Mariannes posts as solution.

so if i made my copy 2 as primary nothing will happen to the state.copy 2 will be copy 2?

[Marianne]

I don't understand why we have to say the same thing over and over.

You had the following:

Copy1      PRIMARY
Copy2
Copy3

Because Copy1 was written first, it was made the PRIMARY by default.

Then you turned Copy2 to primary:

Copy1     
Copy2    PRIMARY
Copy3

See? NOTHING 'happened'  to Copy1. It is still there.
Copy2 also remained Copy2. It just has the PRIMARY 'flag'.
 

If you make Copy3 the PRIMARY, you will have the following:

Copy1     
Copy2   
Copy3   PRIMARY

As I've said before - You can make Copy1 primary again or specify '-copy 1' if you want to restore from command line.

Each backup is assigned a primary copy. NetBackup uses the primary copy to

satisfy restore requests. The first backup image that is created successfully by a

NetBackup policy is the primary backup. If the primary copy is unavailable and

a duplicate copy exists, select a copy of the backup and set it to be the primary

copy.

Copy number does not change; status as Primary can be changed but only one copy is Primary at any given time

Another suggestion:

Keep Copy1 onsite and send Copy2 or Copy3 offsite.

This way Copy1 that is by default the Primary, will be onsite for quick restores and all confusion can be avoided.
