   睇吓咩碟, 早幾日清啲cdr / dvdr, 大牌子既冇問題, cheap 啲既全部讀唔到. 好彩當年冇貪平, 啲可有可無既先用cheap 碟.

其實，我也都想知乜原理，我自己估S記integrity check只檢查 cloud backup file existence, 應該不檢查file integrity, 否則唔會咁快check完

Refer to S記"The integrity check simply checks on backup data to know if the related backup task can proceed and if the backup data can be successfully restored"

Clone the OS Disk to another SSD and keep it separately. In case of necessity, then replace the corrupted OS disk with this cloned/backup SSD.  Simple.
For the HDD with photos, just use FreeFileSyn to back up the whole HDD to another HDD (preferably backup to 2 HDDs), and put them in two separate locations.

如果成個地球爆炸咪乜都無晒, back up 多份放在太空好喎.

for os disk, I use macrium reflect free to create system image files (of course to another hdd) at regular time frame.

freefilesync (mirror mode with verify on) is great!  I use it for daily backup from nas to nas (and also to external hdd), multiple copies.

The requirement of using this approach is, we're willing to buy lots of hdds.

我覺得要平衡簡單和安全, PC/mobile/camera備份去NAS
NAS有raid,有hourly snapshot, 有daily differential backup 去cloud
最後定期check 下 cloud backup integrity
全自動又方便

    ~1T, ~$100/month for MS azure, 不是超便宜, 但可接受, 如果多人用google drive可以平好多
