NAS 既 backup

我公司想買隻 NAS 做 file sharing , 但我擔心如果部 NAS 死左咁咪冇曬上面既 data .

我知有 raid , 如果死碟 , 都可以救得番 data , 但我又擔心唔好彩如果遲發現死碟救唔番 , 或者死 raid card 之類問題 .

想問下 , 公司用 NAS 一般做唔做 backup ? 我地冇 backup device .

我地用 o365 的 , 可以 sync data 去 one drive 當 backup 嗎 ?

CHing,

U will need to do backup for your NAS!  (the NAS itself can crash (e.g. if you attacked by ransomware, your whole NAS data can be gone w/o proper protection / backup!)

E.g. What I do: I will backup to another NASs (a few NAS) (the backup NASs automatically turn on everyday, do backup and turn off (ususally, backup take only 1~2 hr most) after few hours)

Besides, I have two USB (4T & 8T) to do adhoc (usually, once a week) offline backup!

For backup to OneDrive, I think it is possible, but I understand OneDrive (free service) is a bit limited (1T?), if that is enough for your case, then go for it.  (but pls consider the data security (e.g. encrypted before upload...etc.)).  

For me, I use Baidu (additionally from above) to store photos data (it cost me RMB 15/mth for 5T space).

I have my HDD (mostly family photos) failures 1x years ago, it cost me around HK$ 2000 (at that time) to recover (but not really successful), after that lesson learnt, I will invest a little bit more $ on important data backup!

Hope it help!

一買買兩隻NAS, 一隻做backup.

NAS 有app 幫你sync data 去onedrive.
最平既backup 方法就usb drive backup, 抄完data unplug 防止NAS 中毒連你隻backup 都炒埋. 日日都咁做.

好多公司仔唔做backup
我試過有幾年
自己係公司私下做backup (當然係我有權力咁做)
但我無話比公司知
四年後非常黑仔電腦出哂事
最後搵間資料回復公司報價 (其實係我嚟)
我再賣返個Backup比公司當係資料回復成功。
真係天價收費

我公司NAS辦公時段每隔四小時做一次Snapshot (預防勒索病毒),每星期自動做一次大backup去外置USB HDD (預防NAS打柴,就算RAID1資料都冇埋),做完即時自動eject (預防勒索病毒)..

My Home

一隻NAS,一部server,每星期日著server一次
行Windows Update + Robocopy NAS 所有資料
個batch 最後加

shutdown -s -t 60
exit

Backup 完,自己熄埋機
