hendry@knuckles ~ $ bitcoin-cli backupwallet /home/hendry/backup.dat
error code: -1
error message:
boost::filesystem::status: Permission denied: "/home/hendry/backup.dat"
Reddit couldn't help me https://www.reddit.com/r/BitcoinBeginners/comments/aftb91/am_i_running_bitcoin_core/
This is no permission problem.
hendry@knuckles ~ $ touch backup.dat
hendry@knuckles ~ $ ls backup.dat
backup.dat
hendry@knuckles ~ $ rm backup.dat
I suspect the bitcoind -server which runs in isolation as "nobody" is trying to access my home directory, which is a bit of a concern. My user's .bitcoin directory looks fine:
