It has changed to 12 weeks so maybe its just being really slow, my question should be, can you back up the block chain data so that if things go tits up again you dont have to download the whole thing ?

Yea, just make a copy the bitcoin roaming folder to someplace else and if anything happens paste it again in the windows
files.

The location will be C:\Users\User\AppData\Roaming\Bitcoin

You can also download torrents of the latest blockchain or you can even use a lightweight client like Electrum or Mycelium that doesn't download the blockchain.

Also you can write a simple file .bat to start the wallet and set the default data directory inside the btc one, to easier a bit the blockchain manteinance.

I would recommend that you use a client that doesn't need blockchain. Much easier and no disadvantage.

You can also download torrents of the latest blockchain

You can download the torrent here. https://bitcoin.org/bin/blockchain/

But since your download is almost done (just 12 weeks to go), you don't need to use bootstrap torrent. Smiley

Bitcoin Core does have some advantages.
The most important one IMO is the easy-to-use coin control feature introduced in 0.9.0.

Unless you are in a rush for the whole block, use a blockless client for a bit while the core client updates, its what i do on new machines.

Yes I concede there are some disadvantages but to the majority of users, particularly if they are asking these kinds of questions it tends to be easy to use an spv client.

That's true. Different wallet clients have different advantages and disadvantages (or no one would use it and the project would be long dead ) Tongue
IMO, SPV like Electrum is pretty user-friendly (easy backup of the seed, no need to store the whole blockchain, etc) and is a great choice for all newbies.

I would advice maybe use a litebitcoinwallet.
They dont have to download the whole blockchain.
So they are synced pretty fast , I myself use multibit for a while now.
I believe you also have a few others but you will have to decide for yourself.
You can use your wallet.dat file for any kind of wallet right?

I fired up my bitcoin client yesterday to get my blockchain up to date, after a few hours my laptop, without warning, switched off.....after a long boot up I finally get the client going again and find i'm 279 weeks behind.....I left it on overnight and this morning it seems to be stuck on 13 weeks and says "reindexing blocks on disk"

what to do ??

The blockchain data is still there. It just needs to be re-indexed, because the sudden shutdown corrupted something. No need to download anything. The closer the re-indexing gets to the latest, current block the slower it will be, so it might look like it is stuck.

No.

Yes, just send them to the address generated by Electrum. A watching only version is basically a 'wallet' that monitors the incoming transactions of specified addresses without actually offering the ability to send out transactions. They are used in cold storage mechanisms where you want to see how much you have without compromising security - and you can create txs online then sign them offline then broadcast them online, which means your safe.

Make sure the transaction has 1 or 2 confirmations so you know it's picked up by the network.

No, but you certainly want to save the wallet. You never know, someone might send coin's to your old address. If you loose that wallet you've lost those coins.

I think Electrum is deterministic right? So you can't import other keys into it?
