Backup ?'s

[imsoulrebel]

Ok. So I have Multibit as a wallet. I then backup my "keys" is this something I only need to do once. For instance I backed it up when I had say 1btc now I have 3btc do I need to back it up again or is just the once ok?

Another question is say I am using Multibit on my laptop. I backup my wallet on a thumb drive and lose my laptop. can I restore my wallet with any client like QT or does it have to be Multibit?

thx

If you just receive coins, your always safe. Not sure how many addresses Multibit saves in advance in backup, so dont know if it is safe sending without backing up then

MultiBit will let you track multiple bitcoin addresses.  Each time you generate a new address for the wallet, you need to backup again.
