Time Machine setup, advice, and restoring

Most people don't think about backups until something goes wrong. By then, the window to act has already closed.

Most people don't think about backups until something goes wrong: a hard drive failure, an accidental deletion, a stolen laptop, a spilled drink. By then, the window to act has already closed. I help Mac users in San Francisco and Washington, DC set up Time Machine backups from scratch, troubleshoot backups that have quietly stopped running, choose the right drive, and recover files when they need to find something from the past. I work with individuals at home and in small offices, not large businesses or enterprise IT.

My approach

Time Machine is Apple's built-in backup system, and for most people it's the right place to start. It runs automatically in the background, keeps a rolling history of your files going back weeks or months, and lets you restore individual files or your entire Mac without any extra software.

The most common thing people get wrong is drive choice. A lot of failed backups trace back to aging mechanical hard drives, drives that were too small, or drives that were never configured correctly in the first place. I recommend solid-state drives (SSDs) for Time Machine backups: they're significantly faster than traditional spinning hard drives and much less likely to fail without warning. Prices have dropped considerably in recent years, so the SSD option is now the practical choice for most households.

I'll help you pick a specific drive based on your Mac's storage capacity, get it formatted and configured correctly, verify that backups are actually running, and talk through whether you need anything beyond a local Time Machine backup (like a cloud backup for off-site protection).

What I can help with

New Time Machine setup: You bought a drive and need help getting it configured, or you want to start fresh after years without a backup. I'll walk you through formatting the drive, setting backup frequency, and encrypting the backup so your data is protected if the drive ever leaves your home.

Choosing the right backup drive: Not all drives are created equal. I'll recommend a specific model and capacity based on how much storage your Mac has and how you use it, so you're not left sorting through Amazon reviews on your own.

Troubleshooting a backup that stopped working: Time Machine can go quiet without any obvious warning. I can figure out why your backups stopped, whether the drive is still healthy, and what to do next.

Restoring individual files: Whether you accidentally deleted something or overwrote a document, Time Machine lets you browse your backup history and pull out individual files or folders from specific dates, without touching the rest of your Mac.

Restoring your whole Mac: If your Mac won't start, or you're setting up a new Mac and want to bring everything over, I can walk you through a full system restore or migration.

Switching to a new backup drive: If your current drive is too old, too small, or starting to show signs of trouble, I can help you set up a replacement and get fresh backups running.

AirPort Time Capsule transitions: Apple has been phasing out Time Capsule support, and recent macOS versions show warnings that Time Capsule disks are no longer recommended for backups. Future macOS versions are expected to drop support entirely. If you're seeing those warnings, I can help you plan the transition to a supported setup.

Don't wait until you need it

A backup only helps if it was running before something went wrong. The two things I hear most from clients after a data loss situation: "I thought it was still backing up," and "I have iCloud, so it's backed up." Time Machine can silently stop running if a drive is disconnected, if the drive starts failing, or if something in macOS changes. And iCloud syncs your files, but syncing is not the same as backing up: if you delete something, it disappears from iCloud too. Checking in on your backup setup periodically is worth the few minutes it takes, and I'm happy to make that part of any session.

How it works

Sessions are available in person in San Francisco and Washington, DC, or by Zoom from anywhere. Backup setup and troubleshooting often takes about half an hour, though new clients and unexpected problems can run longer, and a full Mac restore will take more time depending on the size of the backup. Rates are on my booking page.

Frequently asked questions

Do I need to buy a drive before I book with you? No. If you don't have a drive yet, I can recommend a specific model and size based on your Mac. You're welcome to order it before our session and I'll help you set it up, or we can figure out what you need during the session first.

Does Time Machine back up everything on my Mac? For practical purposes, yes. It backs up your documents, photos, applications, settings, and more. There are a few categories it skips by default (like cache files or app activation files), but if your Mac fails and you have a recent Time Machine backup, you can get back to where you were.

My Time Machine hasn't backed up in months. Is my data at risk? It may be. Time Machine can silently stop running if the drive is disconnected, if the drive is failing, or if something changed in your system. Don't assume everything is fine just because it was working before. The first step is checking the backup status and finding out what's happening.

Can I use the same drive for Time Machine and storing other files? I don't recommend it. Time Machine works best on a drive dedicated entirely to backups. Mixing personal files with a backup volume creates complications and increases the chance of something going wrong.

I have an old AirPort Time Capsule. Do I need to replace it? Yes. Apple stopped selling AirPort devices in 2019, and macOS has already dropped support for Time Capsule as a backup destination. You might think you can avoid the issue by not updating macOS, but if you unexpectedly need to replace your Mac, the new one will come with the latest macOS already installed, and you won't be able to access your backup. I can help you plan the transition to a supported setup before that happens.

Is Time Machine the only backup I need? For most people, Time Machine pairs well with a cloud storage service like iCloud, Google Drive, OneDrive, or Dropbox. Think of them as covering different risks: Time Machine protects you from accidental changes, like deleting a file or something going wrong with your Mac. Cloud storage protects you from catastrophes, like a fire, flood, or theft, where both your Mac and your backup drive could be lost at the same time. That said, cloud storage doesn't save everything: your applications, system settings, preferences, and anything outside your synced folders won't be there. Rebuilding a computer from cloud storage alone takes a lot of time and effort. A Time Machine backup, by contrast, can restore your entire Mac to exactly where it was, which makes the process far more straightforward. I'm happy to talk through what makes sense for your situation.

How much storage should my backup drive have? A good rule of thumb is two to four times the capacity of your Mac. If your Mac has a 512GB SSD, a 1TB or 2TB backup drive gives you plenty of room for a healthy backup history. I'll give you a specific recommendation based on your setup.

I just got a new Mac. Should I restore from Time Machine or start fresh? I almost always recommend migrating with Time Machine via Migration Assistant: it brings over all your files, applications, and settings in one step and gets you back to where you were quickly. Starting fresh is really only worth considering if your old setup had deep-rooted problems we couldn't resolve, and even then it's a last resort.

Can you help me recover a file I deleted a long time ago? It depends on how long ago and how full your backup drive was at the time. Time Machine keeps older backups until the drive fills up, then starts deleting the oldest ones to make room. If the backup of that file still exists on your drive, I can help you find and restore it.

What if my backup drive itself fails? Am I out of luck? If your backup drive fails but your Mac is still working, your data is fine; you just need a new backup drive and a fresh backup. The riskier situation is if both fail at the same time, which is rare but possible. That's one reason an off-site or cloud backup is worth considering for anything truly irreplaceable.

How do I know if my backup is actually working? Click the Time Machine icon in your menu bar: it shows when the last backup completed and whether there are any errors. If you're backing up to a modern SSD and that status looks normal, you're in good shape.

Should I encrypt my Time Machine backup? I recommend it, especially if the drive ever leaves your home or is stored somewhere others could access it. The tradeoff is that the password is the only way in: there's no recovery option if you forget it. I generally recommend using your Mac login password and putting that in the password hint, so it's easy to remember without being written down somewhere.

What happens when the backup drive fills up? Time Machine starts deleting the oldest backups automatically to make room for new ones. You won't lose your current files, just older backup history. This is normal and expected, but it's a reason to size your drive generously: a larger drive means a longer history to restore from. If your drive fills up quickly, it's usually a sign it's too small for your Mac.

Do you need to be physically present, or can you help over Zoom? Most Time Machine work (setup, troubleshooting, checking backup health, restoring individual files) can be done over Zoom using screen sharing. I'll need you to have your backup drive connected and ready.

Do you recommend using more than one backup drive? Not for most people, but it can make sense in specific situations. If you split your time between two homes, keeping a dedicated drive at each location means you're always backing up locally wherever you are, with off-site protection built in. A second travel drive can also make sense if you spend a lot of time away: you should never travel with your primary Time Machine backup, since if your bag is lost or stolen you'd lose both your computer and your backup at the same time. I can help you think through whether a second drive makes sense for how you live and work.
