    Backup Path Initialized Slow

    Hi,

    I'm running Zimbra OE 8.5.1 and zextras 1.10.2. I started the backup path initialization successfully but the process seems to be slow. Smartscan is been running for more than 24 hours now see the output of the backup monitor below. The backup directory is a NAS mounted on a CentOS.

    Account scanned: 27/287
    Account updated/new: 0/28
    Item scanned: 49500
    Item updated/new/unique: 0/49500/44491

    Hi erwinjmontemayor,

    main bottleneck on backup initialization is the I/O on your NAS, so you need to check statistical infos on that device, not only on server side.

    Have a nice day.
