How to Suspend a Backup

When it is necessary to suspend or stop a backup-in-progress; either a laptop or desktop; it is critical to properly suspend Time Machine's process. Doing so allows Time Machine to properly close out open files and prepares the system to successfully resume the backup at the appropriate time.

To do so, from the menubar; Time Machine> Stop Backing Up. (See image)

This process can take a few minutes to complete depending on the size of the backup set being managed.

This action is the preferred method to simply shutting the lid on the laptop when preparing to change locations. It is also helpful in preventing backup set corruption and delays in processing ongoing backups.
