Hello together,
I'm a little bit confused.
When do I have to backup my wallet.dat?
Just one time or always after getting new transactions?
Is it possible to get all CURRENT bitcoins back with an old backup?
What's the difference between an old backup and an actual backup?
Would be nice if someone could explain it to me.
Thanks
The default client pre-generates 100keys best to back up every 100TXN or less
if you do lots and lots of transactions you can raise the size of the keypool, but still best to backup before that number of transactions completed
the problem is, new change addresses that may not appear in backups that are too old
