Thoughts on Repository Format 6

Info Format

• Info format will be JSON. Something like (but without whitespace):

[
    {"pgbackrest":{"format":6,"version":<pgbackrest version>,"repo-id":<base32 * 16>,id:<base32 * 16>}},
    {"content":...},
    {"checksum":<sha(1/256)hash>}
]

Manifest

• Save all options instead of the piecemeal saves that are done now. These options are for informational purposes only so it would be fine to save them in a KeyValue or JSON blob.

• Store default sections before file/link/path sections to avoid two passes on load.

• Format backup labels using gmtime().

Options

• Disable symlinks by default on posix repos. This is a convenience feature for manual access to the repo and it makes more sense to make it optional.
