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 ,
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 ?
