Windows 機如何避免 silent data corruption

Comeon

一直都用 freefilesync 去做 offline backup 去其他 disk 到
迎日由 file time + size 轉左去 file content file content 去做比較

雖然較耐， 1TB data 用左成 30 幾分鐘先比較完
但發現有 D file 既 check sum 唔岩，之後發現有 D 相下半截出左顏色格
即時係其他地方既 disk recovery 番

之前 search 如果行 linux 就可以行 ZFS file format
但 windows 機又可以點做?

SnapRAID 就係用嚟防 silent data corruption

SnapRAID is a backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures.

SnapRAID is mainly targeted for a home media center, with a lot of big files that rarely change.

Beside the ability to recover from disk failures, other features of SnapRAID are:

• All your data is hashed to ensure data integrity and to avoid silent corruption.
  
• If the failed disks are too many to allow a recovery, you lose the data only on the failed disks. All the data in the other disks is safe.
  
• If you accidentally delete some files in a disk, you can recover them.
  
• You can start with already filled disks.
  
• The disks can have different sizes.
  
• You can add disks at any time.
  
• It doesn't lock-in your data. You can stop using SnapRAID at any time without the need to reformat or move data.
  
• To access a file, a single disk needs to spin, saving power and producing less noise.
