• The catalog is more compact. The binary representations of numbers, dates, and other information, takes up less disk space than the text representations.

• The catalog is much faster to browse and search, especially for large file sizes.

• The catalog supports alternate backup methods without the need to post-process images, which improves catalog performance for alternate backup methods.

The following points describe size the limitations that are associated with the binary catalog:

• The maximum number of files that can be backed up per image:

  (2³¹) - 1 files = 2,147,483,647 files = 7FFFFFFF files

• The maximum number of different user IDs and group IDs (combined):

  (2³¹) - 1 IDs = 2,147,483,647 IDs = 7FFFFFFF IDs
