將會買1隻6TB單碟硬碟

但點樣備份好

1) 買多隻6TB單碟硬碟 - 但比2x3TB貴唔少
2) 買2x3TB - 但有咩方法可以將佢合成6TB
3) 其他?

THX!!!

    有些師兄會建議你買LTO帶機。

6G 個隻拆2個partition, 各自用3T backup 得唔得?

除非係sata唔夠用,用太大都有一定的危險,有事非同少可,
其實以T做單位,巳經很大了,分開两,三只仲好.

source: 11TB with 5 hd
backup server: 13TB with 5 hd (LVM)

Useless !  People won't listen to you

When one HDD fails, just replace the faulty one, then rebuild the raid setup, job done (looks so easy ).  Well, don't take it for granted ... 唔係理所當然架  

If we dig into epc forum, it's not difficult to locate complains on corrupted / irrecoverable raid setups.  Standalone external backup is always the king.   And better make 2 backup copies for all important data.

Backup 的目的,都係唔想hdd 死左時有data 流失
咁用raid 1 做mirror, 再得閒時將file backup 去external device.....

咁先係比較穩陣的做法。

RAID is for higher availability only. It is never a backup solution.

They are different concepts.
