Limit size of data files 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.dat having maybe 700 MB, and not changing (frequently) in the future.
blk0002.dat holding 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?
This is actually already implemented: blk0001.dat contains the first two gigabytes of blockchain data, blk0002.dat contains the second two gigabytes, and so on. We just haven't hit two gigabytes of data yet.
