I plan on using
monerod only for a couple of weeks a year with --prune-blockchain flag to keep
the blockchain data below 20GB. In the meantime I will be reinstalling the operating system of the PC that
monerod will be run on.
When starting anew I want my
monerod to save time on syncing the blockchain as well as to remember previous settings with regard to pruning.
Do I have to backup the entire
lmdb/ directory or just
lmdb/data.mdb? What is in
~/.bitmonero/lock.mdb? Is it needed to start syncing from a backup blockchain data from another computer? After starting
anew do I have to run
monero --detach --prune-blockchain again or is it unnecessary?
