Regarding Duplication

duplication is done at the image level, not the tape level. You can and should demultiplex images that you are sending offsite. The reason is that if you ever need to use them you want to be able to do so at the fastest time possible. There is a switch to enable demux in the duplication policies. The only caveat is that retention needs to be the same for all the images. Don't worry about starting at frame 1. Netbackup will do all the arrainging for you as it will simmply be duplicating images.

Bob,

Duplication completed sucessfully ...but i am facing some problem...I want to know whether it is copy1 or copy2? Actually I initiated duplication for a image located in 2 medias.And it stored in a single meida...I monitored the process from Active monitor while duplication..(that It picks up the new media and read some files from original media then read rest of the files from one more media) then finally duplication sucessfull...../bpmedialist -m of duplicated media shows... the detail..correctly ..that capacity ,mediaid and retention period etc.., but ./bpimmedia -mediaid ...shows ALLOCATION FAILED ..and i unable to search through catalog tab...pls guide me ...how to proceed this? or need to import (first phase)....

Thanks

The original is called copy 1
The duplicate is called copy 2

If you do a bpimagelist -backupid it will show both copies. The second column shows the copy number. Copy 1 is the original, copy 2 is the duplicate.

That is correct!

What is it you want to do with the duplicate copy? By default the primary copy is copy 1.If you want to do a test restore then you need to change the primary copy to be copy 2.

Bob,

Yes it is copy 2 , got the information from the command (bpimagelist -backupid ) , But it is showing list of information... The duplicated media(500118)which holds backup image copy is duplicated from the original medias (In this case 2 medias(500106 and 500109) which contains that backup images ..because it was backed up those images with Multiplexed enabled)..Now from the command ./bpimagelist -backupid gives the output as..

My doubt is ..duplicate done sucessfully ...i monitored that it spans both the original medias......but from that output .... it lists the total backup image fragment of original is 182 but in duplicate is just 18...

The need of this duplication is ... we need to send this 2 original medias to different location ..so i though to make it as single media.......

FRAG 1 is the copy1
FRAG 2 is the copy2

The sum of the sizes of all of FRAG 1
should equal the sum of all the sizes of FRAG 2
If it is demuxed then there may very well be fewer FRAG 2 elements
but the summation of the sizes for FRAG 1 should equal the summation of the sizes for FRAG 2

Yes bob , But i confused in this case.... as per my problem

Fragment 1 to 60 is located in media 500106
Fragment 61 to 182 is located in media 500109

Both the abouve media are Copy 1 and those 182 fragmented backup imaged backedup in this media with Enabling Multiplexing
I duplicated those backup image in a media 500118 and it is copy 2

while duplication i found the process spans both the original medias,after the duplication i can found there are only 19 fragments.

so as per your answer ..... Fragment 1 to 182 in original media is equal to the fragment 1 to 19 in duplicated media? and once duplication done ..we need to do import process for duplicated media for update image database..if yes..will it overwrite the existed original database?
