Time Machine New Computer



Time Machine Backup/Restore Failed

The old machine is definitely showing signs of impending death, so I'm wondering if I can move its files onto my new machine via the Time Machine backup. I'd like to do this without creating a. Open Terminal and type or copy & paste the following command: sudo tmutil associatedisk -a and a space. Drag the new hard drive icon to the terminal window. You may click the Finder and choose Go – Computer to find the icon. Open the Time Machine set (drive or disk image).

Mac users, who're currently running macOS Catalina or Mojave, report that they got an issue with Time Machine. Mainly, it's about Time Machine backup failed to back up the scheduled files to the configured backup disks, let it be the Time Capsule drive or third-party drive. Hence, how to repair Time Machine backup becomes the topic we're going to discuss here.

Issue 1. Can't Backup or Restore Your Mac Using Time Machine

One phenomenon to get Time Machine backup failed is that you can't back up or access an existing Time Machine backup, or restore from an earlier backup won't work. According to Apple's official instructions (https://support.apple.com/en-us/HT204157), when you have a problem with Time Machine, check these things if you see an alert that Time Machine is unable to back up your data, or if you can't select your backup disk in Time Machine preferences.

Fix 1. Check Time Machine System Requirements
  • External hard drive connected to a USB, FireWire, or Thunderbolt port on your Mac
  • Time Capsule or macOS Server on your network
  • External hard drive connected to the USB port of an AirPort Extreme Base Station (802.11ac) on your network
Fix 2. Check Your Mac
  • Make sure that your Mac software is up to date.
  • Restart your Mac and see if the issue continues.
Fix 3. Check your AirPort Base Station
  • If you're using an AirPort Time Capsule or a drive connected to an AirPort Extreme Base Station, make sure that your AirPort firmware is up to date.
  • Restart your base station and see if the issue continues. To restart, unplug the base station from AC power for 5 seconds, then plug it back in.
Fix 4. Check Your Network Connection

If you back up to a server, AirPort Time Capsule, or drive connected to your AirPort Extreme Base Station, make sure that your Mac is connected to the same network as your backup drive. You can select your wireless network from the Wi-Fi status menu.

Fix 5. Check Your Backup

If you back up to a server, AirPort Time Capsule, or drive connected to your AirPort Extreme Base Station, make sure that your current Time Machine backup doesn't have any issues that could prevent further backups:

  • While holding down the Option key on your keyboard, click the Time Machine menu in the menu bar, then choose Verify Backups.
  • If Time Machine finds an issue with your backup, it displays a message with details. Follow the onscreen instructions.
Fix 6. Check Your Drives
  • If you're using a drive connected to a port on your Mac or AirPort Extreme Base Station, make sure that the drive is turned on.
  • If you're using a USB hub or a similar device, try connecting the drive directly to your Mac or base station.
  • If you're backing up to an external third-party drive, check with the drive manufacturer to make sure the drive's firmware is up to date.
  • If you're backing up to an external drive, check the formatting of the drive. Time Machine requires that an external drive be formatted like a Mac startup disk: Mac OS Extended (Journaled) with a GUID Partition Table (GPT). If you select a differently formatted drive for use with Time Machine, your Mac automatically prompts you to erase it for Time Machine.
  • Reformatting a disk erases all data stored on the disk, so you might want to move important files to another disk first.

If your drive is already formatted correctly, turn off Time Machine, then check it for problems:

  • To check the drive of an AirPort Time Capsule, follow the steps to verify an AirPort Time Capsule drive.
  • To check an external drive connected to your Mac, open Disk Utility from the Utilities folder of your Applications folder. Then use the First Aid feature in Disk Utility to verify your disk. Do this for your startup disk as well.
  • You can turn Time Machine back on after your drives are verified or repaired successfully.

Issue 2. Time Machine Backup Is Corrupted

What's a corrupted Time Machine backup? Below are some backup corruption symptoms.

  • Fail to complete Time Machine backup
  • can't access time machine backups
  • Time Machine keeps asking to create new backups
  • Searching for time machine backups taking forever
  • Time Machine disk or external device becomes unrecognized

How to repair a corrupted Time Machine backup? According to some experienced users and professional geeks, when Time Machine corrupted, it can be fixed by the following four troubleshooting methods.

Fix 1. Create New Backup

If Time Machine keeps asking you to create new backups, click Create new backup to start the new backup then. So that it can work smoothly later.

Fix 2. Restart Time Machine

Restart Time Machine several times may also help. You may need to switch Time Machine to On-Off-On and then reboot the Time Machine again.

Fix 3. Swap out The Hard Drive

Another solution to repair Time Machine is to set up a new external hard drive with Time Machine as a backup drive.

Fix 4. Repair Corrupted Time Machine with Terminal command

If Time Machine stops responding or even not working on Mac, to repair the corrupted Time Machine becomes tough yet still resolvable with Terminal command.

Notice:
Before starting the process, You should stop Time Machine: Time Machine Preferences > Toggle Time Machine 'OFF'.
  • Step 1: Open Terminal on Mac and type: $ sudo su - and hit Return.
  • Step 2: Type: $ chflags -R nouchg '/Volumes/.sparsebundle' and hit Return.
  • If you don't know the TM name, go to Time Machine Prefernces and check out. Or type: $ ls '/Volumes/ and hit Return.
  • Step 3: Type: $ hdiutil attach -nomount -readwrite -noverify -noautofsck '/Volumes/.sparsebundle' and hit Return.
  • Step 4: Type the below command and hit Return each time:
    /dev/disk5 GUID_partition_scheme
    /dev/disk5s1 EFI
    /dev/disk5s2 Apple_HFS
  • Step 5: Type: $ fsck_hfs -drfy /dev/diskxs2 and hit Return. After this, if you receive 'The volume was repaired successfully', congratulations.
    But if Terminal warns you 'The volume could not be repaired', relax and continue with next command.
  • Step 6: Type: $ fsck_hfs -p /dev/diskxs2 and hit Return.
  • Step 7: Type: $ fsck_hfs -drfy /dev/diskxs2 and hit Return. Wait for the process to complete.
  • Step 8: Type: $ vi '/Volumes//.sparsebundle/com.apple.TimeMachine.MachineID.plist' and hit Return.
    Change the value of integer from 2 to 0 within that file.

Time Machine is Apple's built-in, set-it-and-forget-it backup system. Time Machine makes hourly snapshots of files and copies them to a backup drive. It keeps older revisions and deleted documents so it can restore them or an entire computer to any point in the past. When the backup drive is full it automatically deletes the oldest backups.

Time Machine works so well it doesn't always get much attention. But if you need to replace computers or hard drives, you'll appreciate these advanced techniques that put you in charge of what happens behind the scenes. Elder scrolls calendar 2019.

Inheriting a backup versus creating a new backup

When you replace a Mac that was previously backed up with Time Machine, you can set it to use the same backup drive as the old Mac as long as there's enough room for both computers' backups.

If you used Migration Assistant to set up the new Mac, at the first backup Time Machine may ask if you want to inherit the backup history of the old computer. Note that even if you choose to inherit the backup, Time Machine cannot pick up where it left off and copy only new files. It always copies everything from the new Mac to the backup. Even so, inheriting can have benefits.

Inheriting a backup allows the user to easily restore files from the previous computer's backup even if they weren't on the computer when you set up the new Mac. And if the backup drive eventually fills up, Time Machine will seamlessly remove the old Mac's backups to make room.

Instead, if you create a new backup Time Machine leaves the old backup set intact and starts a new set. That's great if you plan to continue using both Macs but it's not convenient if you intend to sell or dispose of the old Mac. You may run out of space and have to remove the old backup set manually. That's not always easy because, as Time Machine will tell you, 'backup items cannot be modified.'

Forcing a Mac to inherit a backup

  1. On the new Mac, set Time Machine to use the same backup drive as before. Then immediately turn backups off.
  2. Log in as an admin user and open Terminal.
  3. Type or copy & paste the following command:sudo tmutil inheritbackup and a space.
  4. If the Mac backs up to a local drive, open the backup drive and the Backups.backupdb folder. Drag the folder named after the old computer to the terminal window.
  5. If you back up to a network (such as a Time Capsule or server),mount the backup volume and look for the Mac's backup disk image inside. Do not open it – just drag the disk image to the terminal window.
  6. Click the terminal window, hit return and type the admin password.

Replacing a drive and continuing the same backup

When you replace a hard drive in a Mac that was backed up with Time Machine it's usually considered an entirely new volume. Everything is backed up from scratch. Although the original drive may also show in Time Machine this will undoubtedly take a lot of time and space. In fact, Time Machine may delete a good part of your backup history (maybe all of it) to make room for the new drive. Thankfully, there's a better way.

Associating a new drive with a Time Machine backup

  1. Turn off Time Machine backups – preferably just before you transfer files to the new drive.
  2. Use a tool like Carbon Copy Clonerwhen you replace a drive. This utility makes a clean copy and preserves file ownership & permissions. The less your new drive differs from the original the less Time Machine will have to recopy when you back up.
  3. Mount both the new drive and the Time Machine set. If your computer backs up to a network drive (server or Time Capsule), mount the backup volume and double-click your Mac's Time Machine backup disk image inside.
  4. Open Terminal and type or copy & paste the following command:sudo tmutil associatedisk -a and a space.
  5. Drag the new hard drive icon to the terminal window. You may click the Finder and choose Go – Computer to find the icon.
  6. Open the Time Machine set (drive or disk image). Navigate to the latest backup of your computer. For example, if the backup was called Time Machine Backups and the Mac was called iMac, you would open Time Machine Backups/Backups.backupdb/iMac/Latest.
  7. Drag the folder for the old hard drive to the terminal window. For example, the internal drive might be called Macintosh HD or something similar.
  8. Click the terminal window, hit return and type the admin password.
  9. Eject the Time Machine Backups disk image if you're using a network backup.
  10. Turn on Time Machine and Back Up Now.The next backup may take a while as Time Machine compares the new drive to the backup but only the files that differ will be copied.
