// Package backup handle data backup/restore to/from ZIP format.
package backup

// The backup process can be told to export all data or just for the
// current organization (tenant).
//
// Selected data is marshalled to JSON format and then zipped up
// into a single file on the server. The resultant file is then sent
// to the caller (e.g. web browser) as a file download. Unless specified,
// the file is deleted at the end of the process.
//
// The backup file contains a manifest file that describes the backup.
