Disk Type (which is better or best practice) -Basic, Advanced, Pure disk

Hi Experts,

I'm currently trying to improve backup environment in terms not to mix Basic , Advance or Pure disks for backup.

I've opportunity to delete all basic , advance disks and create one MSDP pool.

Is this right approach ? or how i can use if i have mixed disks type.

Please assist.

many thanks

  • Hey

    Everything depends on your needs... If your data is well deduping and your client do have enough CPU power to run client side dedup if not use media server dedupe side, I would have opted for MSDP for everything... If you have some clients/data not well deduping you may want to back it up to ADV disk STU  and then using SLP, ie. backup capacity managed and duplication to tapes.... If there is such need. For sure I would get rid of the basic disk STUs as these can not be used with SLPs... Of course use SLP also for any backup directed to MSPD, ADV - so your backups will have some lifecycle... Less SLPs the better for your env... That's my two cents...

      Many Thanks quebek,

      I have total 6 media servers (3 for primary site  & 3 for DR site) and except one server, each server has 3-4 basic disks, 1-2 advanced disks. I'm thinking to delete all basic, advanced disks [ofc after duplicate current image to other servers] and create one big MSDP pool on each server.

      But i'm not sure how well i can use if i go with advanced disks or create one msdp pool on each server. (total 6 MSDP pool).

      Thanks,

        Well

        Test on one of them MSDP (along with its counter partener at DR site). The is no 'one size fits all' on NBU end :), so this is the reason you are at this company, right? ;)

  • The previous replies should help you to understand what want to go for. I am adding what you may use the type of Disk considering what you are going to backup to it

    => Compressed Files or Compressed DB Backup - Advanced Disk

    => Normal Unix or Windows Backup - MSDP (you can get better dedupe)

    => Many admin's prefer Basic Disk for Catalog

      Sorry for this question: can use compress option enable with ORACLE RMAN backup? so far i didn't enable it.

      Thanks,

        The best approach would be to check with DBA about RMAN compressed backup, that's more efficient that netbackup compression(though I don't have exprience of using Netbackup compression).
