The subject invention relates to systems and methods that enable pausing and/or resuming a backup of file system items. The items are backed up in an order based on a unique property associated with each of the items. When the backup is paused, the unique property associated with a last backed up item prior to the pause is stored. Additionally, a timestamp associated with a snapshot from which the backup was taken can be stored with the unique property. Upon being resumed, the backup can continue from the paused location via utilizing the stored unique property. The backup can be resumed either employing an original snapshot associated with a time prior to the pause or a second snapshot related to a subsequent time. The subject invention can perform an initial backup of file system items and/or an incremental backup of such items. Additionally, the subject invention can support backing up a file system at disparate levels of granularity such as, for example, an item level.
