Migrating Images between Netbackup Domains

I have a requirement whereby we are replacing 4 x 50x0 Puredisk Appliances with 4 x 5220 Appliances.  The current config has all devices in the same Netbackup domain, even though 2 of the 50x0 applia...

    You cannot AIR or duplicate images from the past using a SLP - but your thoughs about taking it to the 5220 forst and the using AIR via the nbreplicate command would work

    Just duplicate using the catalog section in the Admin Console and while there copy and paste the list out so that you have a list of images and then do a quick script to nbreplicate those duplicated images using AIR.

    I dont think you will be able to automate it but it shouldn't take much to do it all manually and it does actually need an SLP creating at the destination site before you run the command.

    So if you create the SLP at the target server named reverse-air, the username is root and for example the dedupe password over there is cbdb12343, then assuming NetBackup is installed on the C drive and the 5220 duplicated image is copy 2 you can do this ....

    Make a file named images.txt and put it on the root of the C drive on the Master. After copying the image list from the catalog section (highlight all and Ctl-C) paste it straight into excel and then copy the imageid column and paste it straight into the images.txt file so that each image appear on a new line.

    Next make a replication.bat file somewhere and in it put the following (edited as appropriate for your values) - note that this is all on one line:

    for /f %%a in (C:\images.txt) do "c:\program files\veritas\netbackup\bin\admincmd\nbreplicate" -backupid %%a -cn 2 -rcn 102 -target_sts 5220_site_2 -slp_name reverse-air -target_user root -target_pwd cbdb12343

    Try it out with one image first to see if it works

    Hope this helps

A few answers to my own question from a first pass at this:

I created a basic disk STU on the master server and performed a small backup to it - all worked OK.  I then duplicated this backup to the local 5220 - all worked OK so I now have copy 2 on the local 5220.  Reverse AIR test can now begin.

When first attempting this the nbreplicate command is crashing, so I removed the additional parameters as above (target_sts, target_user, target_pwd).  Still crashing.

I then noticed that rcn can only be in the range 1-100, so changed that to be 52 - still crashing.

(The syntax of the (d:\images.txt) is good and all works OK - it is passng in my backupid OK)

My current command resulting from the running of the batch file is as follows:

"d:\veritas\netbackup\bin\admincmd\nbreplicate" -backupid bckpsys_1381232559 -cn 2 -rcn 52 -slp_name Reverse_AIR

I created the Reverse_AIR SLP on the remote master server ONLY, with a retention period of TARGET RETENTION.

Whatever I seem to do results in Netbackup crashing (just this nbreplicate command).  I am running the batch file from a CMD window launched with RUN AS ADMINISTRATOR on the local W2K8R2 master server.

Any thoughts ?
