Encrypt (-c): On what level does it work (granularity)?

Postby sven » Thu Oct 06, 2011 9:04 am

Hi all.

Does encrypt (with option -c) work on the level of single files or blocks or the whole fsa file or ...?
I am asking because I want to understand how much I can restore if the fsa file
will contain a bad block or so.

Compression and encryption are implemented for data blocks level. So if one block is unreadable, it will be able to read the next data block. The checksum for the file(s) this block belongs to will show the file is corrupt. One single data block can be shared when there are many small files (REGFILEM) in order to optimize compression which would be inefficient on very small amount of data.
