Sebetulnya pendapat bahwa backup lewat jalur LAN itu akan sangat lama 
merupakan premise yg tidak tepat. Karena bisa jadi client punya dual 
LAN, satu buat production, satu lagi buat backup.

Masalah fragmentasi LAN packet karena menggunakan TCP/IP juga bisa 
diatasi menggunakan jumbo packet size (big MTU) dan bisa dibantu 
hardware menggunakan NIC yang punya TCP Offload Engine.
Bahkan dalam praktek, implementasi SAN yg menggunakan iSCSI, ataupun 
long distance SAN pakai FCIP router, justru menggunakan Gigabit Ethernet 
yg punya TOE.

Tidak semua proses backup bisa dilakukan secara level block data, 
beberapa masih kudu dalam level file system. Pada level file system, 
otomatis lebih mudah menggunakan LAN dengan cara NFS atau SMB.

Selain itu, investasi SAN itu tidak murah (HBA sekitar US$1000, 
bandingkan dengan NIC GE US$100 atau GE with TOE US$500), dan lebih 
mudah kalau semua data bisa dipool dalam satu lokasi yg sama, di bawah 
kontrol hardware RAID yg superior. Kondisi ini kadang tidak bisa 
dipenuhi setiap saat.n.

Mungkin karena SQL Server *service* (bukan SQL *Server/hardware*) tidak di
shutdown ini penyebabnya. Apakah mungkin database (bukan Server) di shutdown
2-3 jam pada malam/dini hari atau memang _wajib_ 24x7 tanpa bisa shutdown
satu detik-pun? Ngga mesti backup tengah malam kan? Bisa coba jam 4 pagi,
dan nanti waktu anda datang ke kantor, lihat apakah backup sudah selesai
atau masih proses.

Atau kalau mau backup serius, beberapa aplikasi backup, punya "agent" untuk
membackup file SQL Server yang sedang aktif, jadi Service tidak perlu
shutdown.

Maxtor external berada di server yang sama cuma SQL server tidak di shutdown 
karna di-schedule malam hari.
Maksudnya user bisa kerja sampai malem terus backupnya di schedule tengah malam.

  Lancar saja sih, dengan beberapa perbedaan kondisi:
  1. Karena saya backup file data, ada puluhan ribu file besar-kecil.
  Sedangkan anda backup file SQL yang hanya beberapa file.

  2. Saya backup data di server yang sama dengan HDD eksternal. Untuk 60GB,
  butuh waktu sekitar 2 jam. 

  Apakah Maxtor eksternal anda berada di server yang sama dengan SQL Server?
  Mungkin ini ada hubungannya karena trafik via LAN akan lebih lambat.
  Pastikan juga SQL Server anda di shutdown dulu service-nya sebelum backup.

Untuk mempermudah Backup Data dari banyak server dari berbagai Lokasi Area, 
sebaiknya menggunakan Arsitektur SAN (Storage Area Network) Switch. Pada 
arsitektur ini, proses Backup data tidak melalui bandwidth jalur LAN sehingga 
tidak membebani Bandwidth tsb, tetapi langsung melalui SAN Switch ke External 
Storage dan lalu di pindah kan lagi ke LTO (Linier Tape Open). Dan sudah pasti 
jika proses Backup Data dilakukan melalui Jalur LAN itu akan sangat lama. Saran 
saya, Bapak rancang arsitektur SAN Switch, lalu instal Tivoli Software>>Tivoli 
Storage Manager>>TSM Server & TSM Client. Dalam software ini, bisa juga 
mengintegrasikan berbagai macam jenis aplikasi utk Backup & Recovery 
Management, Archive Management, Application Protection.
   
  Semoga bermanfaat.

  Tergantung budget anda sih.

  Kalau saya sih lagi coba solusi murmer, backup ke HDD external via USB.
  Tinggal pasang HDD IDE kapasitas besar, pasang skeduler dan backup built-in
  Win2003. Data harian bisa muat sampai 1 minggu, minggu selanjutnya tinggal
  di timpa ulang.

  Tentunya ada plus-minus dibandingkan solusi normal, seperti tape backup.

Untuk mendapatkan hardware ataupun system dan methodology backup yg 
tepat, anda harus bisa menentukan dahulu :
a. ukuran yang akan di backup
b. backup rotation schedule
c. backup windows time
d. restore windows time for partial and complete restore
e. jenis data yang akan di backup (normal file system, raw, global file 
system, dataase file, etc)
g. budget
h. attended and non-attended operation

dari situ baru kita bisa ngobrol solusi apa yang kira kira anda 
butuhkan. Bahkan kadang bisa jadi anda tidak perlu backup, karena jenis 
datanya TIDAK bisa di-backup.

Soal vendor backup hardware, bisa dari IBM, HP, Quantum, StorageTek, 
Ingenio, Sun, dll.

Yach, otomatis semakin besar kapasitas dan semakin cepat proses backup / 
restore, tentunya semakin mahal. Kami melakukan tukar tambah dengan supplier 
dengan DLT tape station yang kami punyai.

Rekan saya masih menanyakan harga sesungguhnya di supplier.

Tapi masukan dari Pak Albert adalah benar, kita harus tahu berapa besar data 
yang di backup, data growth nya per bulan dan apakah kita bisa meng-archive 
data yang ada untuk memperkecil data growth. Dengan begitu kita bisa 
mempertimbangkan jenis tape backup apa, apakah perlu tape magazin dan berapa 
lama kita bisa menggunakan backup technology itu.

  Perasaan anda ngga pernah kasih tahu kebutuhannya berapa GB yah? Kan tinggal
  di lihat saja, DAT itu mulai dari berapa sampai berapa GB. DLT itu mulai
  dari berapa sampai berapa GB. Super DLT itu mulai dari berapa sampai berapa
  GB. LTO mulai dari berapa sampai berapa GB. Mau yang external atau internal.
  Mau yang satu cartridge atau multi-cartride. Setelah dapat semua parameter
  itu, baru cari yang dibawah bugdet. 

  Dari 4 teknologi tape diatas, DAT paling murah, kapasitas paling sedikit.
  LTO paling mahal, kapasitas paling banyak.

  Ini malah sebaliknya, ada budget tapi ngga ada limitasi kapasitas.

  Cek kapasitas dan teknologi?

http://en.wikipedia.org/wiki/Linear_Tape-Open

Linear Tape-Open (or LTO) is a computer storage magnetic tape
technology developed as an open alternative to the proprietary Digital
Linear Tape (DLT). The technology was developed and initiated by
Seagate, Hewlett-Packard, and IBM. The standard form-factor of LTO
technology goes by the name "Ultrium".

Current Compliance-Verified licensed manufacturers of LTO technology
mechanisms and/or media are IBM, Hewlett-Packard, Quantum, Maxell,
Tandberg Storage, TDK, Imation, EMTEC, Fujifilm, and Sony.

LTO itu tape teknologi terbarunya IBM. Kapasitasnya besar, kecepatannya tinggi 
... Kami sudah pakai LTO, karena database yang di backup sudah mencapai 2 TB 
lebih. Tape teknologi lama magazinnya sudah nggak cukup.

Coba kontak IBM atau perusahaan lain yang menangani backup system untuk 
informasi lebih lanjut.

Tergantung budget anda sih.

Kalau saya sih lagi coba solusi murmer, backup ke HDD external via USB.
Tinggal pasang HDD IDE kapasitas besar, pasang skeduler dan backup built-in
Win2003. Data harian bisa muat sampai 1 minggu, minggu selanjutnya tinggal
di timpa ulang.

Tentunya ada plus-minus dibandingkan solusi normal, seperti tape backup.

Salam
Albert
