'Morning, I have looked in several timemachine threads, but I havn't seen a solution for the use of networkshares with timemachine. So here it is: 1. Close timemachine if it's open 2. Open terminal 3. Type: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1 4. Restart timemachine 5. Select a networkshare for backup Now timemachine creates a sparse image on a networkshare and timemachine works the same way as on a external disk. For me this is a perfect solution so I hope more people can benefit from this.
