Update: Due to frequent powercuts in my area I lost some progress made and had to reindex the blockchain.
I don't have a power backup that keeps my node running continuously but I will do that later when I have that capability.
I am currently at 91% and still syncing. Will update here once the sync is completed. Thanks.
Interesting. Have you considering using a RAID configuration for your hard disk? That should at least prevent disk corruption since only one of the disks will have a corrupted write. But maybe it won't.
Bitcoin score doesn't have a good way of making data backups while the software is online.
