As the mere size of the constantly changing data file tampers with my backup concept, I would like to ask if there is a way to split this file into many smaller pieces. I have no problem with the size as such, but with the amount of changes.
Background is, I do my backups with rsnapshot. This links files which haven't been changed on the target together, while changed files are copied in full.
That's why I would imagine to split the currently about 763 MB big blk0001.dat into two files:
blk0001.dathaving maybe 700 MB, and not changing (frequently) in the future.blk0002.datholding the rest.
As the 2nd file grows steadily, I would, after it has reached a certain size, put more data from it into blk0001.dat, and eventually stop changing this file at all, starting a 3rd one.
Has someone done this already?
3Just in case you're unaware, backing up your bitcoins only requires wallet.dat, not the block chain data. – Meni Rosenfeld – 2011-11-21T14:07:08.667
1Yes, but I don't want to download all that stuff in a case of emergency... that needed me 2 days or so the last time... – glglgl – 2011-11-21T14:38:50.863
OTOH: as I have it on 3 computers, I exclude it everywhere from the backup. Good point! – glglgl – 2011-11-21T14:39:14.357
@glglgl You can always use e-wallets if you really want the emergency access time - https://en.bitcoin.it/wiki/Category:EWallets

And, as I just noticed: if I lose them all, I can re-download them as an archive.
