Q: Time Machine issue with Server 5.0.15 and OS X 10.10.5
I thought this might help others:
I have various servers running OS X 10.10.5 and each backed up to its neighbour by Time Machine to its neighbour. Updating from Server 5.0.4 to 5.0.15 broke this setup without providing any alerts to warn me...
As far as I can tell the combination of OS X 10.10.5 and Server 5.0.15 messes up the permissions of the TM repository - it works only if you opt to allow 'all users' to use your server as a TM repository, which is not what I needed. Anything more restricted than this, I wanted just admin users to have access, causes 'backup disk not available' alerts on the client. A fix that seems to have worked in my case was to use the command line to change the group of the 'Backups' folders and the TM images they contained:
sudo chown -R _ldap_replicator:admin Backups/
The _ldap_replicator (uid 299) user what TM is using to make the connection, which seems very wrong to me.
I thought it might be a starting point for anyone whose backups are broken.
I'd be interested to know whether the same issue arises with OS X 10.11.whatever. I wouldn't normally considering upgrading to OS X10.11 this early but I do like my backups to work properly...
