Backtrack 1 3. Hello dmw100,
Ok the good news is I have Time Machine back-up (and it last did so last night). I can view my files and folders and access them if I plug Time Machine HD into my ibook. So they are there. When I go into 'Restore from Time Machine Back up) I can access the Time Machine HD ok. Lack of permission to the backup database folder is the NO.1 reason why your Mac can't connect to a Time Machine backup disk. You can check if there is a permission problem with your Time Machine by opening the Time Machine disk in Finder and going to Time Machine Backup Backups.backupdb folder. Question: Q: time machine won't backup I have a first generation MacBook Pro Retina Touch Bar and the 2 TB SSD - have been backing up to Time Machine via wifi/Synology for a while now without issues. Just updated to 10.14.3 Mojave from the previous Mojave version today, and since then, I cannot get Time Machine to do its thing.
Welcome to the Apple Support Communities. I see you've been running into some issues backing up using Time Machine with network attached storage.
Have you double-checked to make sure your configuration meets the requirements to back up using Time Machine? It sounds like you may be using a configuration that doesn't include an AirPort router, so this could be a factor as outlined below:
Before using Time Machine, you need an external storage solution, sold separately:
- 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
- If your backup drive isn't connected using one of these methods, Time Machine might not work. Check with the device manufacturer for compatibility and connection information.
This article has some great steps that may be helpful for general backup issues with Time Machine: If you can't back up or restore your Mac using Time Machine. If you find these steps don't resolve the issue, I recommend contacting Synology to look in to this further: Contact Us
I hope this helps get you started.
Cheers.

Time Machine Won't Back Up
After finishing a Time Machine backup, when trying to access the Time Machine backup, you got an error that said: can't connect to a current time machine backup disk. The error stopped you from accessing your Time Machine backups and what's more, your files inside the backups.
Here is how to fix the error 'can't connect to a current Time Machine backup disk' and show you how to restore files when you can't access the Time Machine disk.
Apple Time Machine Troubleshooting
Why Can't Your Mac Connect to a Current Time Machine Backup Disk?
Here are the reasons why your Mac can't connect to the current Time Machine backup disk.
- Your Mac doesn't have the permission to access the Time Machine backup database folder.
- If your backup disk is directly connected to the Mac, there could be a connection issue between the disk and your Mac.
- If the backup disk is a network disk, your Mac can't connect the backup disk because of network disconnection.
- If you are using Time Capsule, Time Capsule could be the culprit.
- If your backup disk is connected to another computer, make sure the computer isn't in sleep.
Solution 1: Check the Time Machine backup disk in Finder
In the Dock, click on the Finder option to open a Finder window. You should see your backup disk under the Device section. If you are unable to see the backup disk in the listing, it is possible that the disk is turned off, disconnected, or defective.

Solution 2: Grant permissions to access the Time Machine backup
Lack of permission to the backup database folder is the NO.1 reason why your Mac can't connect to a Time Machine backup disk. You can check if there is a permission problem with your Time Machine by opening the Time Machine disk in Finder and going to Time Machine Backup > Backups.backupdb folder.
If you see a red stop sign in the Backups.backupdb folder and can't open the folder, you don't have the permission to access the backup folder.
It is quite easy to grant permission to access the Time machine backup and enable your Mac to reconnect to the Time Machine backup disk.
Now, open the Terminal application on your Mac.
Enter the command line: cd /Volumes/TimeMachineDriveName. (Replace TimeMachineDriveName with the actual name of your Time Machine disk after /Volumes/. This takes you to the Time Machine disk that your Mac can't connect to.)
Next, enter the command line: sudo chgrp admin Backups.backupdb. This changes the group permissions so that the admin group on your Mac can access the Time Machine backup folder. And you will be required to enter the passcode of your Mac twice to confirm the change.
After the permission change is made, go back to Time Machine and see if you can enter your backup now.
Solution 3: Reconnect your backup disk to Mac
If your Time Machine backup disk is a physical external hard drive, it is possible that the backup disk is disconnected so that your Mac is unable to connect to the backup disk. You can reconnect the backup disk.
Remove the backup disk from your Mac, then re-plug it to your Mac.
Also, make sure the backup disk is turned on with the power source available.
Solution 4: Reselect your backup disk in Time Machine preferences
If you see the error 'can't connect to a current Time Machine backup disk' after you have erased the backup disk, reselecting the disk in Time Machine preference can help to fix the error. Follow the steps below:
Step 1Run System Preferences and select Time Machine. Or open the Time Machine Preference from the Time Machine menu bar. Audirvana plus 2 5 1 3 download free.
Step 2Click on Select Backup Disk.
Step 3From this list, select the external drive you want to choose. Select 'Encrypt backups' and select the Use Disk option.
Step 4As per the requirement of Time Machine, if the disk you selected is not formatted then you are prompted to format the disk.
Solution 5: Verify backups for a network disk
Verifying backups is only available for a network backup disk. If the backup disk is a network disk, make sure the Mac has a stable network connection and verify disk using Disk Utility on your Mac.
Step 1Go to Finder, select Applications, and click on Utilities and double-click Disk Utility.
Step 2Click the Time Machine backup drive on the left panel.
Step 3The Verify Disk option will be displayed on the right panel.
Solution 6: Restore lost files without Time Machine
If none of the methods above can get your Mac connected to the Time Machine backup disk, maybe the disk is damaged. Luckily, there is a way to restore lost files without Time Machine backups.
Recoverit Data Recovery can be installed on the Mac device to recover lost files. By using the Recoverit program, you can easily recover a minimum of thousand types of files on Mac even you don't have a Time Machine backup available.
Download and install Recoverit on your Mac and follow the following steps:
Step 1Launch Recoverit. Select a location to restore the deleted files and folders on Mac. The location should be where the deleted files were stored.
Step 2Click Start to scan a disk to search for the deleted files. You can check the deleted files during the scan.
Step 3After the completion of the scan, preview the deleted files on the device, and click on recover to save the files back on the computer.
By following the above-mentioned steps, deleted files and folders on Mac can be recovered without Time Machine.
