In spite of having a UPS and an AC/DC inverter for the house, I am now on IBD #3, with days to go. And the Dex DAO is suspended until I can reach current block height. 5 seconds faulty Win shutdown = Disaster.
Have you checked why that happened? Faulty UPS or AC/DC inverter? UPS ran out of power before the computer shutdown properly?
a. Copy/paste or delete old and replace new?
If i have lots of free space, rename the old directory then "copy/paste" the backup and wallet file from old directory. Otherwise i would perform "delete old and replace new" for blockchain file.
Based on your responses, I’m most interested in finding out if a complete backup and restore is possible.
If you really want near complete backup/restore, you either need to setup your hardware to use RAID 1 or use data mirroring software. Personally i'd rather backup the files occasionally.
