Hi All,We like to migrate data from US to Canada. We like to rebuild the servers the servers from US to Canada. We have 20 servers backed up in US which we want to migrate to Canada by backup. We do backup of the servers using nb5220 7.5.0.7 V. We like to rebuild the servers in canada by importing the catalog in Canda. Please advise how can we achive this. What are the stpes we need to take to achieve this and how using the Netbacku catalog.USA:Existing setup: 7.5.0.7 runs on nb5220IBMTS3310 library with LTO-5 tapesCanada:Existing setup: 7.7.2 runs on Windows 2012IBMTS3310 library with LTO-5 tapesRebuild process:We create a new servers in Canada and restore using Netbackup one by one:C:drive, system state , reboot the server and local drives restore.

That sounds like a plan. For tape import see:Step-by-step procedure on how to import NetBackup backup images via the NetBackup Administration Console GUI.https://www.veritas.com/support/en_US/article.TECH43584.For compatibility your problems might be:i) Do you have LTO5 or LTO6 at the target site?ii) Were the tapes encrypted at the sourcse site?iii) If yes, then which type of encryption? (dongle in a library, external third party Key Manager, we know/believe that any tapes cannot have been encrypted with NetBackup KMS or NetBackup MSEO because were not supprted on early versions of appliances).iv) Tapes written at the source site using a bigger/larger/longer SCSI block than is configred at the target site. It is highly likely that the source site appliance is writing tapes with 256KB blocks. If the target site read/import/restore NetBackup server has not had SIZE_DATA_BUFFERS configured to be 256KB then you might not be able to read the tape..You cannot afford to have your igration weekend go wrong, so here's what I would do to test is beforehand......at source site:1) create two 1GB sized files of random data2) take an MD5 and SHA1 checksum of both files (use the free MS tool named fciv for this)3) backup just these two files to tape4) ship tape to target site...at target site:5) import phase 16) import phase 27) restore two files8) checksum two files at target site9) compare checksums from source site with checksums at target site

If you see tape pool name(s) beginning with "ENCR_" at the source site, then it is very likely that NetBackup KMS is in use. For NetBackup MSEO, I do not know how to confirm whether this is in use or not, so hopefully someone else will confirm. For NetBackup Client Encryption, you need to check to see whether "Encryption" is ticked/selected on backup policies.Personally I would test that Windows OS recovery process first before you come to rely upon it during the actual migration. Myself, I've never seen it work.I myself would not advise any OS recovery restore overlay method, for Linux or Windows or Unix. NetBackup BMR exists for a reason.

Hi,Simplest method in this case is to ship the tapes to Canada and import them. NetBackup has functionality that can replicate data on appliance between domains called AIR, but you'll need to upgrade your 7.5 environment, and even then, AIR is more designed to start replicating from that point onwards. You can however replicate images from cli using the nbreplicate command. I suppose it depends on how much data you're talking about.

Next important questions:10) For the "server" (i.e. backup client) restore at the target site, are you planning on NetBackup BMR based backup client (i.e. whole server) recovery, or will you be restoring whole virtual machines?11) Are the 20 backup clients to be restored all of the same OS family and same OS versions?12) Are there any databases running within the 20 backup clients to be retsored? If yes then you will need to carefully consider, and I dare say practice, whole server and database recovery for these.

Yes, NetBackup v7.7.2 on Windows can read tapes written by v2.5.4 Appliance (aka NetBackup v7.5.0.7) ... assuming of course that...i) tapes are not encrypted, or that similar encryption is configuredii) target read tape drive is LTO5 or LTO6 (nothing else will work)iii) buffer sizes match.Actually being able to read tapes is one thing. Actually being able to restore a whole working server, or twenty of them, is a completely different story.

  Ok. Thank you. Can I create new virtual machin with Linux platform in Canada. Install the 7.6.1.2 Master server package , then copy the Catalog via WAN , import it to new server from nb5220 ?. Is this possible ?.

    Not possible within the parameters and constraints as described by you. Normal customer actioned catalog recovery is only ever possible between the same NetBackup version, and only rarely also additionally sometimes across OS families of the same bitness. All I can offer for your encouragement right now is that the concept "seems" that it "might" be viable if you were operating "perhaps" within a different set of constraints.
    You cannot catalog recover from a catalog backup from an Appliance to a Windows server - never. You cannot copy the raw catalog from Appliance to Windows either, it simply will not work.
    One option might be to build a new empty SUSE EL 10 SP4 Linux VM in Canada, install NetBackup v7.5.0.7 and then try a catalog recovery.
    .
    There are some hints elsewhere in this forum that you might be able to restore a catalog:
    ...from: Appliance v2.5.4, SUSE EL 10 SP4, NBU v7.5.0.7
    ...to: own build VM, RHEL v?.?, NBU v7.5.0.7
    ...but I cannot vouch for it myself, and you will need to identify a supported version of RHEL.
    .
    I think Riaan's answer is the best answer because it presents the least risk to your backup data across all backup platforms - but like Riaan said, it depends upon the volume of data.
    If you realy must do it via Catalog manipulation ascross OS families and NetBackup versions then you will need a Veritas Certified CatMan Specialist. Contact your local reseller for more details.

Please lookup 'Recovery without import'. This is a pdf doc that describes how to perform a partial catalog recovery on a different master.
Take care that you add all moved tapes to a pool that will never be used for backup (eg RESTORE).
You need to ensure that all tape copies moved to new site are made primary. Otherwise restore on new site may want to restore from MSDP.

  Thank you all for valuable suggestions. I got the idea to take full backups to tape and then ship the tapes to Canada. So I am not taking the catalog tape. Only the data tapes transferred. So I will import the tapes in Canada library and use it in Canada netbackup server to update these images in catalog. This option is available after 7 version irrespective of platform. My environment here again.
  
  USA nb5220.
  7.5.0.7
  Ibm TS3310 with lto5
  Maximum 2 lto5 tapes cover data to migrate
  
  Canada windows 2012
  7.7.2
  Ibm ts3310 with Lto drives
  
  I just need the confirmation about any compatibly issue. And commands import the data tapes in Canada and update the catalog.please advise.

    You cannot afford to have your igration weekend go wrong, so here's what I would do to test is beforehand...
    ...at source site:
    1) create two 1GB sized files of random data
    2) take an MD5 and SHA1 checksum of both files (use the free MS tool named fciv for this)
    3) backup just these two files to tape
    4) ship tape to target site
    ...at target site:
    5) import phase 1
    6) import phase 2
    7) restore two files
    8) checksum two files at target site
    9) compare checksums from source site with checksums at target site
