Overview

In order to prevent data loss, it is extremely important to back up your files regularly. Data is “backed up” when it is saved in at least two locations. This can mean on the internal hard drive of your computer and on an external hard drive, on two external hard drives, or on a hard drive and a cloud service. In this article, we’ll go over backup methods including Drag-and-Drop, Time Machine, and cloud services such as such as Dropbox and Google Drive.

 

Data saved on only one piece of storage media (such as a single hard drive) will be irrecoverably lost if that device fails. Laptops are increasingly built without replaceable or removable components, which means that if any part of your computer breaks, your hard drive and the data on it may become inaccessible. Additionally, if you are having your hardware repaired or getting an updated software build, it is essential that you make a full backup of your data beforehand.

 

External Hard Drives

External hard drives are plugged into your computer’s USB port and provide extra storage space. They can be purchased online or at electronics stores and usually start at about $60 for 1 terabyte (1000GB). If you work with large amounts of data, you may need multiple external hard drives.

 

Choosing an external hard drive: There are many totally usable brands of hard drives. Western Digital, Seagate, LaCie, and Samsung are a few common ones. You can choose between “hard disk drives” (HDDs), which contain spinning disks and are often more affordable for larger amounts of data, or “solid state drives” (SSDs), which are significantly faster with newer technology but cost more for smaller amounts of storage space. You also want to consider the type of cable that comes with the hard drive - for newer laptops with USB-C ports, you may consider buying a hard drive with a USB-C cable. When shopping for a hard drive, simply Google search your preferred size and brand (if any) and look for a product with a large number of positive reviews. Bonus tip: 2TB hard drives are often only $10-$20 more than their 1TB counterparts.

 

Setting up your external hard drive: When you first get your external hard drive, it will need to be “initialized” or “formatted” before you use it. Some hard drives will arrive formatted as NTFS (Windows format) and will prompt you to install a driver to read it. For best results, however, you should instead follow these instructions for reformat it as MacOS Extended (Journaled) using an application called Disk Utility. If you’re planning to use the drive with both Windows and Mac computers, you may consider formatting it as ExFAT. Important: “formatting” your drive is the same thing as erasing it! If your external hard drive isn't recognized by your computer when plugged in, visit our article about external storage troubleshooting.

 

Drag-and-Drop Backup Method

One of your options is to back up your data manually. If you choose this option, please also read the section below this one on checking your backup! Once you’ve plugged in and initialized your external hard drive, you can simply drag and drop (or copy and paste) the data from your user folder on your computer (a folder usually named after your MCAD username) to your external hard drive. We recommend opening two Finder windows side by side: one to view the data on your computer and the other to view a new folder on your external hard drive where the backup will be stored (you may want to include the date of the backup in the name of this folder). Drag each folder from the first window (Desktop, Documents, Pictures, etc.) into the folder in the second window and wait for the files to copy completely.

 

 

This is an effective way to back up your files, but it requires more manual attention and will not back up data that is stored in hidden folders, such as bookmarks, sticky notes, locally stored Apple Notes, app preferences, and other data. This method may be preferred by users who don’t store very much data locally on their computer. For a more complete and automatic backup, use Time Machine.

 

Checking Your Backup (Beware of Aliases!)

Once you’ve made a manual (drag-and-drop) backup of your data, it’s a good idea to check that data to make sure it really is saved on your external hard drive. One risk is accidentally creating “aliases” of your files, which are basically links or shortcuts that point to the original file rather than a true copy of the data itself. If the icons of the files/folders that you dragged and dropped to your external hard drive have little black arrows on them (see screenshot), they did not copy properly and are NOT backed up!

You can also confirm your data is properly backed up by looking at the sizes of the files/folders in your backup to see if they match the sizes of the original data. You can do this by clicking on a file in column view mode and viewing its details in the pane on the right; you can also right click a file or folder and select “Get Info” for more details including the file size. If you ever want help confirming your backup, stop by the Help Desk.

 

Time Machine Backup Method

If you are on a Mac, you can use Apple’s Time Machine utility to make a full copy of ALL data on your computer’s hard drive, including hidden folders and other user accounts. This method is recommended for faculty or staff who are upgrading to a new computer. 

 

To use Time Machine, your hard drive must be formatted MacOS Extended (Journaled), as described in the “Setting up your external hard drive” section of this article. Plug in your external hard drive, connect your computer to a power source, and open the “Time Machine” section of System Preferences. Use the “Select Disk” button and find your external hard drive.

 

There are checkboxes you can select to enable automatic backups or to place the Time Machine icon in your top menu bar. From the icon in the menu bar, you can manually tell your computer to “Back Up Now” when your drive is plugged in, even if automatic backups are off. For detailed instructions with screenshots, see this Apple Support article on Time Machine.

 

Backups are stored inside dated folders within a folder called Backups.backupdb on your external hard drive. The first time you make a Time Machine backup, it often takes many hours for it to make an initial copy of your computer’s entire file system. You may want to plug your computer into power and let it run overnight. After this, subsequent backups will be very brief, as Time Machine only needs to copy data that has been changed since the last backup. 

 

Transferring Your Data Back

Sometimes it is necessary to transfer data from a backup to your computer (for example, after having your computer reimaged or repaired, or after a hard drive failure). If you created a manual backup using the drag-and-drop method, the process is almost exactly the same but in reverse. If you created a Time Machine backup, you usually do NOT want to Time Machine’s built-in “Restore” or “Inherit” options. This will cause errors as your computer tries to transfer old versions of software and preferences. Instead, you should manually drag and drop your data from the user folder in your backup to the user folder on your computer, just as you would for a manual backup. For assistance with this or help locating specific hidden data, contact the Help Desk.

 

File Servers

Students have some limited storage space on their studio server (found at afp://studio.mcad.edu) and on the class server (afp://class.mcad.edu). Learn more about the class server here.

 

For Staff: MCAD's file servers provide a safe and secure location for MCAD data. Windows users primarily work off Maverick to store individual and departmental files. MacOS users can use their individual staff network home directory or a specially configured departmental share for file storage. Please contact the MCAD Technology department or your staff supervisor to determine which overall network storage solution is best for your office needs.

 

Cloud Backup Services

Google Drive

The MCAD institutional Google accounts provided to most faculty, staff and students come with unlimited storage space in Google’s cloud storage service, Google Drive. This can be a great place to store copies of important files and works particularly well for sharing data between users. You can also install Google Backup and Sync, a service that will automatically back up the data in selected folders on your computer to your Google Drive.

 

However, once you leave MCAD, your MCAD Google account will be deactivated and any data stored within the associated Google Drive must be transferred to a personal account before access is lost (see our article about Graduating or Leaving MCAD for instructions). Personal Google accounts only come with 15GB of free storage, but more can be purchased for a few dollars a month. 

 

Dropbox and iCloud Drive

Dropbox and iCloud Drive are both alternative cloud storage platforms that work similarly to Google Drive. Data is stored in an online repository connected to an account you have created. While both can be used effectively, at this time we do NOT recommend using iCloud drive as a primary backup method due to a variety of issues we have witnessed with this service. Contact the Help Desk for more details. 

 

Retrospect

Certain Faculty and Staff have the data on their MCAD computers backed up to our institutional backup service, Retrospect. This service is offered to department directors and chairs, and select others who handle large amounts of sensitive data. In order to back up to Retrospect, users must have the Retrospect client properly configured on their computer and must periodically connect their computer to Ethernet. For more information about Retrospect, please see the ITS Workstation Backup Policy.

 

As always, please contact the Help Desk with any questions about backup methods or data management.
