The first hard drive is damaged

The first time I lost data due to a damaged hard drive was around 2010.

At that time, the price of BTC was about 7-8 dollars, which is equivalent to about 40-50 RMB.

At that time, many websites were giving away small amounts of BTC for free, and I also received 0.02 BTC at that time.

At that time, the laptop hard drive was suddenly damaged, and all the data, course materials, homework, and BTC were lost.

The third hard drive is damaged

Today, history repeats itself again

Because of luck, I have a NAS at home that is not configured with RAID 1. Today, my home suddenly tripped. The storage space of the NAS was directly destroyed, and all applications and data were destroyed.

Fortunately, this is not the first time my hard drive has been damaged. The data on this NAS has a daily scheduled BACKUP

Fortunately, I only needed to restore the data step by step

Unfortunately, the recovery process was extremely bumpy as the backup data had never been restored before.

Summarize experiences and lessons again

1. All NAS requires RAID 1
2. Back up important data!!! Back up important data!!! Back up important data!!!
