Time Machine and FreeNAS

While working on getting Time Machine backups to work with my FreeNAS box, I ran into a permission issue with the dataset I was using.

My recommendation to get it working on more than one machine (so you can use the same dataset for TM backups on multiple machines):

  • Setup a specific user for the backups (I used “tardis”)
  • Change the permissions for the dataset being used for backups so that the owner and group owner are your new user (for me, “tardis”)

After that change, along with all of the other ones outlined at the FreeNAS documentation website, I have been able to go ahead and use that new user to setup the new ZFS dataset on both laptops for Time Machine backups.

Awesome.
