bitcoin-qt "backup wallet" vs copying wallet.dat I am new to bitcoin, I wander what are the differences, and pros/cons (if any) between the file generated by bitcoin-qt when clicking on &quot;backup wallet&quot; vs copying the file &quot;wallet.dat&quot;? I see these files are indeed different with &quot;cmp&quot; so I am assuming that there are differences between these files. Can one of these files recover all of the information in the other?
EDIT: after a few backups I noticed that if I close the wallet, and then wait a few minutes. A backup at this moment equals the wallet.dat file.
Maybe its copying it safely in a way that you can re-use it without any issues.
Update and lock the wallet, preventing any file corruption caused by updates during the copy
