To expand on this a bit more, SLP's sole
function is to guarantee that your destinations/copies that you have defined
will happen. The only thing to note is that SLP only takes over once the
initial backup has completed, so if the initial backup fails, you will
have issues. To do this, SLP will actually set copy1 to infinite expiration
until it has satisfied the additional copies. I can't remember exactly
how it is, but I believe in the first 3 days, it will try several times
per day to complete that copy (based on your configuration), and then after
that it will try once per day. You should still watch the number of images
you have that are not completing via the nbstlutil command, though.

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.

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.

Subject: [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 ,
