Given the selection of container format, have you considered compression
algorithms for the whole container that meets your requirements? The
majority of popular compressors require an out-of-band index to facilitate
random access without additional seeking.
Minor inconsistency in the requirements:
The requirements for the on-disk archive format include:
- support for archives greater than 8GB in size,
- support for files in archive greater than 4GB in size,
...
The cpio format was rejected for the following reasons:
- The size of files in portable cpio archives is limited to
(8 * 2^30) bytes.
