But I remember I asked about symlinking method to separate chainstate folder from blocks folder and also other members also asked about it and basically the consensus was that it was very unsafe and would corrupt the block or chainstate files...
As far as I know, the unsafe part happens if your symlinked location becomes unavailable. That's not something I worry about on my own system though (worst case I'll need to restore a backup).
I was wondering about the actual connection between blocks and chainstate folders
can we recover/rebuild one by using the other? which one is more important?
recently my wallet (btx based on btc) ask to rebuild the blocks because corrupted issue
but it keeps failing on rebuilding the blocks and I ended syncing from my last backup
every now and then I make backup by
copying blocks and chainstate folders, is this the correct way to backup blockchains?
