How much memory in the Mac? Hard disk drive, or solid state? Which version of the OS? Time Machine is a remarkably good citizen with modern versions – *if* the Mac and its disks are treated normally, gracefully. If force is applied to shut down or to restart of the Mac, or if a disk is improperly ejected (red alert), or if a backup is interrupted: Time Machine must spend more time than normal. How much more time? It varies. In my case, before I moved from HFS Plus to ZFS, the abnormal times were unacceptably abnormal. Hours, and hours, and hours. With HFS Plus alone: partitioning a disk (fewer files per file system) can dramatically improve the behaviour of Time Machine after any ungraceful event. But partitioning does not suit all use cases. -- You received this message because you are subscribed to the Google Groups "Sussex Mac User Group" group.
