[aarons6]

i have my wallet encrypted on my pc..
i just changed this password.. i was wondering if i have to reback it up or if the backup i have, which is secure, is still ok with the old password.

Your question is not clear.

If you backup your current wallet, then the backup would have the new password.

If you want to restore an old backup created before you changed the password, then it will use the old password.

i was just wondering if there was something in the system that would make my old backup not work if i changed the password.

The old backup will still work, you will just need to use your old password and any addresses generated after changing your password will not be in your old backup.

Indeed. Encrypting or changing the password on the wallet.dat you are currently using will not be reflected on any copies you have lying around on cloud drives or other media.
You need to be a bit careful!

In particular,  the wallet will generate new addresses after the password was changed that the old wallet won't know about. So your old backup will become increasingly invalid over time.

The password is purely for encryption purposes. If someone has an older wallet.dat and can guess the password they'll get the private keys. Sweep if you're not sure!

I learned the hard way.

How so?

Got an old backup cracked or current ?

The wallet also re runs the benchmark to determine the number of SHA-512 rounds when setting a new password. On a more powerful system it will improve the defense against brute force attacks on the wallet file.
