NBU 10x tape 2 tape copy (inline copy) clarification.

Question

Hi people:We have a 4 drive LTO9 library, Master/media server is Windows2022 and NBU 10.1.2. I have some policies that do a two tape copy of data to different pools. For example, mydata policy have two schedulesforeverfull schedule make a backup to Mypool01 (primary copy on tape1) and its copy is located in Mypool02 (second copy on tape2) with retention level 100. Most of the time the policy make the two tape backup and copy successfully.monthlyfull schedule make a backup to Monthpool01 (primary copy) and its copy is located in Monthpool02 with retention level 10.Sometimes tape1 o tape2 fails over the copy&nbsp; (HW errors mostly, like need cleans drive) and then just use bpduplicate to make the copy over the tape of the respective pool.Today I have some doubts about the correct syntax, because I need to copy a backup with two copies made with monthlyfull schedule (the backupid is server01.net_1705357985)&nbsp; to use foreverfull pools and change the retention level.My question/doubts are around the -npc; should I use it? Of course, I want that backups on foreverfull schedule&nbsp; remains as primary copies.bpduplicate -v -number_copies 2 -backupid server01.net_1705357985 -client server01.net -dp Mypool1,Mypool2 -dstunit mylibrary-01-hcart3-robot-tld-0 -id 000012 -L copi.wri -policy Respaldo_servr01 -rl 100,100Can anybody give some ligth about this?&nbsp;

Run the bpimagelist command to see if the backupid is in the netbackup database, how many copies are and where they are .
bpimagelist -backupid server01.net_1705357985

Again, you do not have to add so many arguments in the bpduplicate command. Keep it simple.
The folowing command will use the primary copy to create another one.
bpduplicate -v -backupid server01.net_1705357985 -dp Mypool2 -dstunit mylibrary-01-hcart3-robot-tld-0 -L copi.wri -rl 100

You cannot change the copy number of a backup copy. Only to make it primary. use
bpduplicate -npc x -backupid server01.net_1705357985

I suggest you use SLPs to create the two-copy strategy. Using the two-copy configuration in the schedule will lead to missed copies if a copy fails. With SLPs, no matter what, you will have two copies automatically.

The command you provide will create two new copies.
I assume that you want to create one copy of the backup with the backupID server01.net_1705357985. The simplest command that does the job is (-v and -L are optional but recommended)
&nbsp;
bpduplicate -v -backupid server01.net_1705357985 -dp Mypoolx -dstunit mylibrary-01-hcart3-robot-tld-0 -L copi.wri -rl 100
&nbsp;
All other parameters are not needed. You may use them as search criteria if you do not use backupid.
If you need to create two copies from a backupid then use
&nbsp;
bpduplicate -v -number_copies 2 -backupid server01.net_1705357985  -dp Mypool1,Mypool2 -dstunit mylibrary-01-hcart3-robot-tld-0,mylibrary-01-hcart3-robot-tld-0 -L copi.wri  -rl 100,100
&nbsp;
-npc is to change the primary copy, and it is not essential. If I remember correctly, you cannot use it with other paramiters but only with backupid to change the primary copy, and it it does not do duplications. To change the primary copy during duplication, use -set_primary.If you omit set_primary, then the infinity backup will become primary when the first copy expires.
Last, you can not have two primary copies. Only one copy is the primary and is used for restores.

Hi people at first tryActivity monitor job id = 1189Copy 1 activity monitor job id = 1190Copy 2 activity monitor job id = 1191The number of specified storage units must be equal to the number of copiesSo weirdly have to specify the same -dstunit mylibrary-01-hcart3-robot-tld-0 twice separated with comas.

Hi people, 3rd tryActivity monitor job id = 1195Copy 1 activity monitor job id = 1196Copy 2 activity monitor job id = 1197INF - Skipping copy 2 of backup id server01.net_1705357985, is not required copy 1.All jobs are queued since NBU says there are no drives available. But on NBU just two driver (from a previous backup) are used. The same says the library remote panel two drives on use, two empty. Yes the dsunit is configured as robot number: 0 and have on 4 the Maximum concurrent write drives.&nbsp;
