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 ,
