Answer: If it is truly bricked, then you need to utilize your backup of that wallet.
If you have lost your only copy of your wallet, then my condolences. The loss of your BTC can be considered a cost of doing business, though - the price of learning from this mistake and instituting better data security practices in the future.
On having a backup: Two copies of your wallet introduces more opportunity for unauthorized access, but more data security in terms of protection.
It would be best if your backup wallet is stored in a physical safe.
Also, to reduce your risk, it might be wise to have a master wallet (I use Coinbase) and a second traveling wallet.
Just like you store money in the bank but only carry a small fraction of the total around in your pocket.
Myself, I stick with just Coinbase and their app. These devices are throw-aways. But the data must be protected.
