More advanced commands available in tmutil include: The first two are required to be run using sudo. Tmutil snapshot forces a new local snapshot to be made. Tmutil disablelocal turns local snapshots off, but does not affect regular Time Machine backups when they are possible, Tmutil enablelocal turns local snapshots on,

There are three verbs which are useful for dealing with local Time Machine snapshots, which are typically made on laptops when they are away from their full backup drive: This can give you an idea of the space consumption to expect on your backup volume, thus indicate how long it will take for existing space to be used up. (use tmutil machinedirectory to discover that for use here for ). You calculate the amount of change between the backups (the ‘drift’) in an individual machine directory with Checksums are a useful basic check of backup integrity. Where is the path to an existing backup which you want to check. To check the integrity of an existing backup, use

This may be helpful when a backup is making no further progress, rather than just forcing a restart. To force a backup which is currently in progress to come to a halt, use Would force my Mac to start making a backup to the destination listed above, from the destinationinfo verb. You can also specify the backup destination with the argument -destination, e.g. If you supply the -rotation argument, then backup destination rotation will be allowed during the backup. To see the ‘machine directory’, which is the full path to the top level folder of backups, use Which simply lists their paths, with the most recent shown last.

To see a list of all completed backups, use This can be useful for confirming location, and the datestamp of that backup. To discover the path of the latest backup, use Which should return a list, usually containing a single member, such as To obtain information about backup destinations which are currently configured for Time Machine, use There is more accessible information, and a full set of controls for Time Machine, in the command line tool tmutil. Although the answer will almost certainly be hidden somewhere in those logs and reports, the question is whether you will ever find it among them, or even recognise it if you did see it. There is a huge amount of information here, most of which is unintelligible to Mac users, and which can readily consume hours of your time. logs/oslog.archive is a dump of the entire new-style log which can be read into Console and browsed there.

logs/install.log is the last macOS update log,.Beware, though – it is very large, normally over 100 MB, mdsdiagnostic/system_logs.archive is a dump of your entire system log which can be read into Console and browsed there. configuration/exclusions.txt contains a useful list of your exclusions from backups, and those set by macOS,.there are full diagnostics on Spotlight, because of the role of its metadata in retrieving information from backups,.brctl contains lots of detailed information about iCloud,.details current settings for the backupd-helper daemon,.backup_destinations contains a complete analysis of your backups, with the log for each one,.What you get is around half a gigabyte of bewildering detail.

Which will save the zipped archive into your Documents folder, for example. It is only accessible from the command line, and when invoked will spend the next few minutes generating a zipped archive of around 290 MB of extracts from logs and much else: it is the Time Machine equivalent of the general sysdiagnose command.

You can then browse your logs using Consolation or the Terminal command log show, but it can be difficult to recognise what is going wrong, and even tougher to work out how to fix it.Īpple provides a monster of a tool, tmdiagnose, to help its own support engineers work out what is going wrong with Time Machine. If your problem is that Time Machine backups are not being started at all, or are only occurring irregularly, then I have explained how you can trace the fault, and given details of the sequence of events which results in a backup being made.īut many problems with Time Machine occur during attempts to back up, when the process aborts with an error message, or, even worse, simply gets stuck and never completes the backup. Once you have turned it off and back on again, and restarted, you will probably be running out of ideas. There are only a few things that you can do to try to address Time Machine problems using normal ‘friendly’ tools such as the Time Machine pane in System Preferences.
