DS218+ 加2隻Ironwolf 4TB

如果唔行raid,另一隻單純backup用會唔會好浪費?
因為唔想再連多隻external hdd

如果 2 隻 , 一隻拎黎單碟用 , 另一隻用黎做 backup , 建議做 backup 個隻買另一個牌子 , double 容量的

有冇hdd推介?如果行raid1再開埋snapshot唔再額外做backup風險大嘛?
私人相片我會再做cloud backup,其餘都係影片多⋯

Raid 1 好過無。。。
如果相片外其他data都唔仲要可以用住raid 1先。
到直係唔夠用再轉返Basic.

又或者。。。用住一個hdd先。遲啲有需要再買個新hdd。

2 bay NAS 行 raid1 最穩陣. 加埋 snapshot + cloudsync cloud backup. 夠晒.

不過而家外接 usb 碟唔係幾貴, 多個備份比較安心D.

IMO, raid1 is a kind of wasting system resource for a 2-bay nas

My setup for a 2-bay nas would be:
1. hdd1 and hdd2 in basic mode, snapshot with sufficient retention period
2. hdd1 is the data disk
3. hdd2 is the data and backup disk (the allocation is up to individual user's need)
4. an external usb hdd for backup

Whether we are using raid1 or basic, an external usb hdd for backup is still a must.  This is the first backup copy of all files that are deemed important.

We can make use of hdd2 for additional data storage as well as holding a second backup copy of very important files only.

As backup should always be 'standalone', point 3 (better than none) is not as reliable as point 4 (as far as backup is concerned).

ps.
Yet we could have another external usb hdd for the third backup copy.  This is optional.

其實2bay名符其實嘅兩悲,行raid1又驚兩隻一齊炒丶行單春各自獨立又驚即死…

PS: 一部機內兩隻一齊行一隻做backup唔代表backup…俾人hack或唔小心就全炒,只有offline backup才算安全…

今時今日,HDD Size 又大又脆弱,

較安全計,最少要兩部NAS 做online mirror

me就算幾多bay, 都唔會行raid,
simply the best,  全部行ext4, btrfs.

有乜衣郁,如HDD無壞,起個linux, 兩野就read/write
返d  file.

行唔行 raid...
我覺得只有 data 的話可以只行 basic volume
但如果有 service, 例如 VM, 最好行番 raid
