Archive index file created by Genie Timeline, a backup and recovery program for desktop computer and mobile device files; contains the index of a collection of files that the user has chosen to backup; may reference a single archive or a multi-volume spanned archive; used for restoring the backed up files.
Genie Timeline creates the GBP index file at the end of a backup session. Without this file, the backup cannot be restored. GBP files are created with the naming conventions backup.gbp, backup.X.gbp, and backup(X).X.gbp, where "X" is a digit.
Genie Timeline can be used for incremental or full backups and can incorporate optional compression.
NOTE: Genie Timeline Backup uses .ZIP compression for backups, so you can use any Zip decompression utility to manually examine the contents of backup files.
