Partition Backups

We have EV 12.0 and NetBackup 8.1.

We had our vault store partitions for mailbox and journal archives on a Centara, but now we are migrating to a Isilon.

I have to backup the vault stores now and I'm having slow throughput <500kb\sec

I reading that I should keep the vault stores size 400-500 GB for keeping backup windows short. 

How do I tell the size of a partition? I can run a vault Store Usage Report, but that does not give me partition size. 

Do I Create Roll Over partitons for my mailbox archiving and journaling archiving partitions?

Is there a limit to number of partitions that can be created?

 

Thanks

Pat

    Hi,

    I assume you use 2 Isilons/Centera's? with replication?

    Why backup? I use Centera's for journal data, no backups there.

      We are retiring the Centera and using the Isilon now.

        Hello, again,

        Let me rephrase :-). Both devices are in general used to perform replication to an identical device. Using a Centera has benefits where the EV Centera API informs EV items are secure. Isilon does not have that. (I know, we're in testing phase). The Isilon in DC1 is replicated to an Isilon in DC2. This replication is fast, and (so I am told) secure. Having to backup TB's of data, where you know the data is replicated, is (sometimes) overkill.

        I 'solved' it by setting the Vault Store (and it's partitions) that use Isilon in backup mode, write a triggerfile (IgnoreArchiveBitTrigger.txt), then take the VS out of backup mode. EV will then consider all files created before the date/time of the triggerfile as secure, and update the databases accordingly.

        If your backup is slow, it might have several reason. You should involve your backup solution vendor, and perhaps EMC, to assist you with that.

        Does that better clarify?
