[Podcast] Technical Tips for Time Machine Backups
For this week’s podcast, Partner Success Technician, Kevin Williams and Technical Trainer, Jackson Camp will walk us through the process of backing up a Time Machine backup to a share point on a Datto device.
Essentially, we’re going to create a Network Attached Storage (NAS) share on one of the devices whether it’s SIRIS device, ALTO, or Datto NAS. Once you configure your preferences, you’re going to point the Time Machine to the actual share so the Datto device can take over and facilitate the backups both locally and offsite.
Focusing on the SIRIS device itself, keep in mind when you’re creating the data share in the SIRIS, it has to be private. In addition to that, make sure you save the credentials for the users you add. Lastly, when you’re configuring the share of the SIRIS or ALTO device, enable AFP/Time Machine so it’s facilitating that communication properly.
The process for creating a NAS share on a DNAS device isn’t much different. We have the same first few steps, setting the share as private, ensuring at least one user is added, and AFP is enabled. Additionally, we have a some more configuration options. You will set up a snapshotting schedule. This determines how many times per hour during a given hourly schedule that the device will take a point-in-time reference of what your NAS share looks like. You’ll be able to have recoverable instances of your time machine backups at any given point in time you set up. This is a very useful feature that provides additional redundancy. After you set up these preferences, you’ll have to offsite these snapshots.
Finally, you have to set up retention. Retention is the process by which we’re removing older iterations or older snapshots of the NAS share based on how long they’ve been there. This is important for saving space. As you can imagine, these snapshots can take up quite a bit of space, especially if you have a considerable amount of incremental data change.
Depending on which device you went ahead and set it up for the whole point is that you’re going to need to actually point the Time Machine to the share. On the Mac device just go ahead and use Command + K to connect to the server. From there, type in afp://the ip of the data//, and then the same of the share.
Once you go ahead and enter that, you’re going to want to enter the credentials for the user you previously selected to be added to the share. This allows you access. Next, you will navigate to the system preferences for the Mac you’re working on and open up the time machine preferences. In this panel you should have a switch on the left side that says on or off. Turn it on. Now you select the disk you want the Time Machine to back up to. Select the name of the share which should pop up as a disk in the list within the box that they present to you.
You may want to go ahead and open up your terminal and enter the following command. The command defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1.
Once you turn this on, try reconnecting to the share. This issue only arises on newer versions of OS10 but it’s a good thing to keep in mind.
