Not only are external drives inexpensive, one and only one backup device isn't a robust backup strategy anyway. So, my recommendation is to obtain another TM backup drive, create a new backup with it, then erase the existing drive.
At best it should be considered unreliable, and an unreliable backup is worse than none at all. It gets worse though, because if you manually erased backups using the Finder (which is not clear to me yet) it's very likely the TM database was rendered invalid and and unusable for purposes of restoring an entire system. If that's the case, you would need to erase the drive anyway because Time Machine "owns" that drive and everything in it. Collapse the "reveal triangle" adjacent to "MacBook Air" to determine if another backup of that Mac is present, under a different name. If there is another folder within it, that would be the redundant one I speculated might be present. Since that screenshot only shows the contents of "MacBook Air" I cannot be certain it is the only folder within Backups.backupdb. It should contain one and only one folder within it, bearing the name of the Mac it's backing up. The short answer is that you will need to erase that TM backup drive, but before you do that back out of that first screenshot that shows the contents of "MacBook Air": NB, whilst I've been typing this I checked the Disk Utility and it has processed slightly. Apart from that I haven't altered anything else.Ĭan you advise how I delete the TM backup drive? I certainly don't want to delete anything that cud make the drive not function.
Regarding your last sentence about not deleting files I'm afraid I have already done that because as per the alert, I needed more space. But the only things that I last saw on the ext HD is 'Backups.backupdb' (unsure of the db part, but the rest stood out) and my last TM backup.
But with leaving it alone I can't examine its contents like you advice. As it is stuck I can either get out of it or leave it alone. I had years of TM backups and when I saw the alert I just deleted lots and so therefore was surprised to see the alert of not enough space.Īt present Disk Utility seem to be struck in the First Aid process so possibly it has found an issue, but not telling me yet. My 1 TB is more than enough storage on my ext drive. But could this be an issue for my external drive? It hasn't stated anything in relation to my ID. Apart from the above issue it seems fine. I have still kept my previous ID User as per advice to ensure the new one is ok. Via call to Support I set up a new User ID for me the Administrator.
