Hi all, Quick story: Time machine has stopped backing up to a network drive, instead saying I do not have the correct permissions to use the time machine backup.
Longer story: I have backed my laptop to a firewire drive attached to my mac mini for years. The backup is on one of three partitions on the external drive, because I back up three computers to the same large hard drive. I changed the backup to an encrypted backup back in November. No problems. I updated my mac mini to High Sierra. No problems. I put a new SSD drive in the mac mini, which changed its file system to APFS. Backups didn't work anymore. So..., I had to change sharing to use SMB instead of AFP, because of the APFS. I had set the partition to be a possible target for Time Machine backups. Unfortunately, however, now when I try to back up, I get an error saying 'You do not have the necessary read, write and append privileges on the selected network backup disk.'. Even better, the error says as a note 'Please connect as a different user or contact your network administrator.'. I've contacted myself repeatedly, to no avail. I have even invoked the names of countless greater beings and lower forms of life, all to no avail. If I go to the mac mini and try to add a file to the partition, I have to authenticate (the permissions are drwxrwxr-x root wheel). This is probably where the problem lies, but I (sadly) didn't look up what the permissions were before I started having problems, so I don't know if a TM partition is supposed to have such draconian permissions. FWIW, the partition for the mac mini's own backups has the same permissions, and it has no problem backing up over the firewire connection. If anyone has any tips, I'm all ears. Cheers, Bill <rant>Unhappy once again with changes made by Apple without a whole lot of documentation or testing.</rant>
