Currently, I am using NEM Community Wallet, not the nano version. How can I back up this wallet? Thanks!
.
I would also backup the private key. Not just the .wlt file.
I backup my private keys to a 7z file that is encrypted with a 63 character password stored in a QR code I scan with a 2D barcode scanner. I also backup the wallet and wallet password in there for redundancy purposes.
You could also store them on lastpass if you had a sufficiency secure setup (long password, 2 factor enabled)
2D barcode scanners make password management so easy assuming you know how to print out and laminate a QR code and store it somewhere secure that’s with you at all times, like your wallet.
There’s a lot more cheap 2D barcode scanners on ebay now at good prices than when I originally came up with this idea.
This site can save offline where the QR code can be generated in a secure enviornment.

A laminated QR code is idiot proof… it won’t forget the data, especially if you make a backup, the data doesn’t change… it’s a digital representation of any information you put into it.
One more website for you… where I generate my random passwords:
i would backup private key in this http://cryptosteel.com/
Is fireproof, waterproof, shockproof and stainless. And i would bury it under my house garden.
How can I backup the private keys?
To back up your key using the nano wallet, click on the word “Account” which is near the upper right side of the screen next to the word “Node”
enter your wallet password where it says “private key” and it will show you your private key for that wallet/address.
For the android wallet, here’s a video guide I found.

I do not use android wallet, I am using ubuntu linux, and I acces to my wallet via firefox via NEM Community Client.
The other question is where the blockchains are stored in ubuntu?
What is export for lightwallet option for?
And I if I print out the private key and remote private key, will it be enough for backup?
for your wallet you need the private key. thats the most important.
the remote accounts public key is important in case you want to change from NCC to nanowallet. i am not sure about the importance of the remote account private key, but i generally also back it up.
lightwallet is another kind of wallet that followed NCC i think, used by many nodes on the network i think. the export is specific for this because lightwallet works differently than ncc im guessing. for nanowallet it would be the same but this has been implemented in the nanowallet instead of in ncc (nanowallet recognizes NCC backups and upgrades them on import)
