    Moving Zimbra with Powerstore to a new server

    Hello. I have a Zimbra server 8.7.1 with a Powerstore 2.4.3 working great (Amazon S3), but I'm creating a new Zimbra Server more robust for my business. My doubt is if possible to migrate my old server to new one with no problem and how to do it.

    Best regards,

    Sergio Bergamini

    Hello Sergio!

    Migrating to a new server is very easy with Zextras Backup, you can find several guides on our Wiki about the different migration paths you can take

    One thing worth noting, since you are using the S3 integration is that such feature, just like everything in the Powerstore module, is completely transparent to the Backup: this means that, unless you select the "Apply HSM policy now" option in the final step of the Restore Wizard, if you migrate to another server all the data will be migrated to the "current" primary volume and then you'll have to set up your volumes from scratch - including the S3 one. The "Apply HSM policy now", however, drastically reduces the restore speed so I'd suggest to run some tests to check whether this is a viable option for you.

    Have a nice day,

    Hello Cine. I started ZxBackup (SmartScan) the last saturday (01/28/17), but since yesterday the proccess is stuck on this status

    Account scanned: 15/226
    Account updated/new: 0/18
    Item scanned: 106400
    Item updated/new/unique: 0/106404/94445

    Folder size is the same, since yesterday
    root@mail:/opt/zimbra/backup/zextras# du -sh
    21G .
    root@mail:/opt/zimbra/backup/zextras#

    Has some thing to do in this case?

    Hello Cine. I move all my mailboxes to new instalation. I activated the powerstore on a new server but its create a new folder in AWS with different name.

    How can I change/move it (old instalation) to a new server? I was thinking to use "doVolumeToVolumeMove", but my volumes are in different servers.

    Best regards,

    Hello Cine. I did copy all data from AWS S3 folder (refer to old server) to another folder (refer to new server), all folders are the same but the new Zimbra Server with Powerstore does not "seeing" messages older than 60 days (HSM is set this way). I move my massages between server using imapsync. After that I ran "zxsuite powerstore doCheckBlobs start" and returns this

    Volumes to check: all
    Mailboxes to check: all
    Search all volumes: true
    Traced: false


    - stats -
    checked volumes : 3/3
    checked mailboxes : 0/227
    checked items : 926923
    checked blobs : 782339
    correct items : 926923
    missing blobs : 0
    unexpected blobs : 0
    blobs with wrong digest : 0
    items per sec : 44.32
    volumes with empty or no folder : 1

    - notes -
    Skipped index volume 2 - index1
    The ZimbraStorage volume seems unused, as no items pointing to it has been found in Zimbra's database. No checks will be done on said volume, and any file in it should be considered as an "unexpected" BLOB.


    I don't know what I do to fix this problem.

    Best,

    Hello Sergio!

    After moving to a new server the Powerstore indeed creates a new folder in the S3 bucket to hold data, as volumes are strictly server-specific and not interchangeable (direcory and item names are based on mIDs and itemIDs, which change during the restore). When items are restored, those are all created in the Primary volume marked as Current as it happens with all Zimbra items, and can then be moved again to a secondary volume using Zextras Powerstore as you did on the old server: manually moving or copying over data between folders is not suggested nor supported for the aforementioned reasons.
