Tech Tip #90 Doc Saved Over? Try This

In these 169 tech-centric situations, you get an overview of pedagogy—the tech topics most important to your teaching—as well as practical strategies to address most classroom tech situations, how to scaffold these to learning, and where they provide the subtext to daily tech-infused education.

Today’s tip: Try this if you saved over a doc

Category: Problem-solving

Q: A student saved a blank document over their files. How? Instead of ‘open’, they use the menu command ‘save-as’ and lose all their work. Is there any way to retrieve the file?

A: Absolutely. In PCs, right click on the file in Windows Explorer and select ‘Restore previous version’. Select the latest version that’s not today. Admittedly, this doesn’t always work, but it’s worth a try.

In Google Apps, simply visit the Revision History and select a version prior to the save-over.

In Macs, there may be an older copy in the Time Machine—it’s worth checking.

World Backup Day–March 31st Every Year

1 Comment

March 31st is called World Backup Day. At least once a year, backup your data files to an external drive (like a flash drive). This is one that isn’t connected to your local computer so can’t be compromised if you get a virus. It’s good to always backup data to cloud drives or a different drive on your computer but once a year, do the entire collection of data files to what is called an ‘air gap’ drive–one that is separated from any internet connection.

How to do this

There are various ways to back up your data. You can back up your data to an external device or a cloud-based backup service, or to both. You might even make more than one backup to external storage devices and keep the two copies in different places (providing protection and access to your data even if one of the backup devices is destroyed or inaccessible. Preserving your valuable documents and images for future access and use requires planning, as well as the use of automatic backup services.

To back up PC/Windows, use Windows Backup:

Click the start button.
Go to Control Panel
Select ‘Backup and Restore’
Select ‘Backup Now’

From there, select a drive with sufficient space and start. Be forewarned: If you have a lot of data, it takes a while. You can work on your computer while it’s backing up; it’ll just be slower.

Mac: Use the Time Machine tool.

Chromebook: No need. Everything is saved to the cloud. Now if you want to backup your cloud, use a service like Backupify.

#71: Beginning Graphs in MS Excel

How to Prepare for College

Succeeding in college is both easy and hard. It takes planning, drive, and dedication, but once you commit to the required changes, the payback is worth it. The first big tip: College is not like High School. Succeeding in the former in no way predicts success in the latter.

With High School graduation close, college on the horizon, one of our Ask a Tech Teacher contributors put together a list of great tips and ideas to help you prepare for one of the biggest steps you can take to build your future:
