[Box Backup-dev] blocks

[Nick Knight]

Is a client sided block stored on the server as a complete file? Also
does the file contain information about the block as a header?

Thanks again

Nick

Within a BackupStoreFile, a block is an arbitrarily sized chunk of =20
data, from 1 byte upwards. (You can get 1 byte blocks if you insert 1 =20
byte within a file and it gets diffed.)

On the server, regarding the storage limits, a block is whatever size =20
is set in raidfile.conf.

Both are separate concepts, and refer to completely different things =20
which aren't used together.
