I'm running bitcoind (086) on a dedicated linux machine with about 35Gb of disk space. Earlier today I discovered the machine ran out of space (blockchain was 33 gigs) and proceeded to delete the whole directory. Now all bitcoins in the wallet are missing, balance shows 0, although I did back up and restore the wallet.dat file.
Is it normal for the blockchain to grow to that size?
Is there another way to clean it up periodically, say, via a cron job?
Should I keep hoping that the missing coins will return to the wallet somehow, maybe after it downloads the blockchain again?
