I am not 100% clear on this and would like someone to explain.

I read that you can have problems if you backup, spend some, and then load the outdated backup. This is because you will have the key to the already spent coin, but not the key to the "change" that was generated and is not in your backup. So you need to redo the backup after every transaction or risk having unspendable coins.

I think a solution to this would be to have a "savings account" that rarely receives transfers and always keep a backup of it. And have a "spending account" that you wouldn't be devastated to lose.

You'll want to make sure that wherever you copy it to, no-one else can get access to it.

Yes. But make sure you stop BitCoin before doing that.

Just to make sure, being new to Linux it took me a minute to figure out what to do to get some result. What I did is:

cp ~/.bitcoin/wallet.dat walletbackup.dat

Is this file an effective backup of my wallet?

Copy the wallet.dat file somewhere safe and secure.
To be 100% belt-and-suspenders safe, shut down Bitcoin before doing the copy.

wallet.dat is:
  Linux/unix:  ~/.bitcoin/wallet.dat
  Windows: %APPDATA%\Bitcoin\wallet.dat  (I think; I don't run Windows)
  Mac: ~/Library/Application Support/Bitcoin/wallet.dat

Can someone please tell me how to backup the bitcoin wallet?
