Frequently asked questions
1. Will a free backup program delete data on my external drive?
No. Reputable tools create their own backup folder or container and do not erase unrelated files.
2. Can I restore files to a new computer?
Yes. Most free Windows backup tools can restore to new hardware, image based tools in particular.
3. Is file backup enough, or do I need system image backup?
If you only care about documents and photos, file backup is enough. For complete disaster recovery, system image backup is better.
4. What is the safest setup?
Schedule automatic nightly backups to an external drive, and now and then test restoring a few files to check that the backup is intact.
