[技術討論] Question on Raid system

I have a question on Raid system.

i am planning for use 2x 512GB SSD run in Raid 0, and then use windows server software raid system for Raid 1 backup to 1~2TB HDD.

512GB SSD (R1-A) \
                                     >--------- 1TB Raid-0 (R1)  system disk
512GB SSD (R1-B) /                              |
                                                                  |
                                                          1~2TB SSD (Mirror on windows server software raid-1)

Is it ok?

You still need an offline full backup for data safety!

1. realtime的話delete錯file即刻bye bye, 呢個唔叫backup
2. 一組RAID一組non-RAID 即係速度有分別, 兩組唔同speed既一齊RAID = 拖慢哂

Always perform monthly/weekly usb backup.  水電問题令raid disk 壞,只少都仲有最近backup

重要野, RAID 唔 RAID 都要 backup 架啦, 關咩事, 次次一講 RAID 就有人彈出黎 RAID =/= backup
樓主個 case, 條SSD RAID 0 會俾 HDD RAID 1 拖慢, 而且比起就咁行單隻 1~2TB HDD 仲要慢

FreeFileSync can scan for file changes on a user defined time interval, and run the sync script when file changes are detected.

Would you please tell me what kind of data would be stored in the RAID? What do you use it for?

If the files on the RAID each file are relatively small and rarely change and, FreeFileSync would be a good solution.

All you need to do is run the sync script after files are changed, or use RealTimeSync to check for changes every hour or even every minute, and keep every reversion of the files in the process.
