The SSD on my 2015 MacBook Pro died, and I got it replaced with a used SSD from another MacBook containing Catalina. The machine boots now normally, ready to restore from backup. I tried to restore from Time Machine backup in the Command+R mode. I can connect to the Synology NAS where I have the TimeMachine backups, and see the backups of our family. When I select my "Peter's MacBook Pro" backup as the source, it churns for about 2 min with a "Looking for macOS system backups..." message, then shows a "No macOS system backups were found" message. So I can't proceed with the restore. Logging in to the NAS I can see that the backup is there: directory Peter's MacBook Pro.sparsebundle sub-directories bands and mapped, the latest files in there match the day when the SSD failed, e.g. it's the most recent backup) files info.bckup, info.plist, lock, token, 4 files starting with com.apple.*Googling I found that the extension changed from .sparsebundle to .backupbundle in Catalina, so I renamed the directory, and tried to restore again. No luck, same error, so I reverted the name change. I suspect the reason why the backup does not work is that the OS is different. I think I had High Sierra, but I am not sure. I looked at the files in the backup, but none of the content of the XML files indicate the OS version. I also tried to downgrade the OS from Catalina to High Sierra, but got an error message. I am currently making a copy of the backup to an external 2 TB hard disk (the backup is 1.25 TB), which should finish in 7 hours. I am at a loss this time. Any idea how to get the backup recognized? UPDATE 2023-03-21 I tried the Migration Assistant approach, I can connect to the NAS, and see the list of backups of all family members. My backup is stuck in "Loading backup...". I left it for the whole day, after 8h it reverted back to the screen where you select the server to restore from. Any other ideas? UPDATE 2023-04-27 After many trials and errors I got the restore finally working: rename the extension from .sparsebundle to .backupbundle connect Time Machine to the NAS => it'll state no backups do a backup => latest backup shown as of today reduce the quota of the Time Machine user to have 500G free space left do another Time Machine backup => this forces Time Machine to clean up the backup and get rid of older snapshots enter Time Machine => older backups are now shown! restoreMoral of the story: Do not rely on Time Machine, it's too buggy! I am installing an rsyc cron to sync all files below my home directory to the NAS. I still use Time Machine, which is useful to restore single files. I am posting this here in case anyone has the same issue. |
