Backing up files
Pages and images are handled separately:
- Pages are packed together into a zip file* and downloaded.
- Images are packed together into a zip file* and downloaded.
- As an alternative one can use "Differential backup of images" where one specify a previously downloaded zip-file. The modification dates and sizes of those files are compared to the remote files and those file who haven't changed are reused (and packed together into a new zip-file)
- The file-times uses UTC time. (Most zip-packagers uses local-time (a big drawback of the zip-format))
Contains site.csv, page.csv, image.csv and redirect.csv files with meta data.
The usage of zip-file might change
I'm considering to use my own packageformat Meta_format_for_Archive_and_compression_formats
, where one can add own metadata in a simpler way like hashcodes, unixtime, access rights ...
