Backup Zimbra

Filed under: Email — dh @ 3:15 am

Beberapa metode backup zimbra

  • backup image (VPS)
  • backup folder /opt (scripting, rsync -avP /opt destination)
  • backup mailbox per user (scripting)
  • otomatis backup (network edition / third party zextras)

Item yang harus dibackup di Zimbra:

  • account dan password
  • alias
  • resource
  • distribution list
  • domain
  • preferance
  • data mailbox

Cara backup restore Zimbra dengan Zextras

  1. di zimbra lama, export dengan zextras migration tool (gratis)
  2. di zimbra baru, import dengan zextras suite (trial 30 hari)

Note: pastikan export sudah selesai, baru install zextras suite (faktor trial) . Proses export memakan waktu sangat lama data 1TB membutuhkan 15 hari.  Setelah diimport, setiap akun email dapat export email dari tanggal migrasi (yang tertinggal di server lama) dan diimport ke server zimbra baru.

Supaya Bisa Terima Email dari Internet

Filed under: Email — dh @ 3:13 am
  1. Domain yang digunakan harus ada/aktif/asli
  2. IP publik statik
  3. DNS management (konfigurasi MX record dan A record)
  4. port 25 incoming

Alasan Menggunakan Remote SMTP

Filed under: Email — dh @ 3:12 am
  1. IP terblacklist
  2. email masuk junk/spam folder
  3. IP publik dinamik/tidak punya IP

Filed under: Email — dh @ 3:11 am
  1. ping IP 8.8.8.8
  2. ping nama domain (google.com)

  4. open port 25 out (cek firewall server dan router)
  5. request open port 25 di ISP
