A recent house fire near one of our team members’ new home in Alabama was a stark reminder that data loss is not always caused by a failed hard drive or an accidental deletion. The home—only four houses away—was a total loss after a grill-related fire, along with anything inside it: computers, external hard drives, and local backups.

For many people, a backup plan begins and ends with an external drive sitting next to the computer. That is better than no backup at all, but it will not protect you from fire, flooding, theft, or a major electrical event that affects everything in the same location.
The Rule: 3-2-1
At MacMedics, we recommend following the 3-2-1 backup strategy:
- Keep at least three copies of important data.
- Store those copies on at least two different types of storage.
- Keep at least one copy off-site.
The basic principle is simple: a backup is only useful if it survives the same event that harms the original computer.
Our Time Machine Strategy
For local Mac backups, we use Time Machine—but we do not rely on a single drive.
We maintain three separate encrypted Time Machine drives:
- One stays at home.
- One stays at work.
- One remains securely locked away off-site.
Every few months, we rotate the drives. This means there is always a recent backup away from the computer and away from the primary location. If there is a fire, flood, break-in, or hardware failure at one location, another copy is still available elsewhere.
Encryption matters, too. An off-site drive can be lost or stolen, so it should be protected with a strong password. Encryption helps ensure that, even if someone gets hold of the drive, they cannot access the information on it.
Why We Recommend Backblaze
A rotating Time Machine system provides excellent local protection, but cloud backup adds a layer of protection that does not depend on a physical drive making it out of the building.
That is why we recommend Backblaze Computer Backup. For approximately $9 per month, it can continuously back up a Mac or PC, including attached external media drives when they are selected for backup. It offers unlimited storage for eligible computer and attached-drive data, which can make it especially valuable for large photo libraries, video projects, and client files.
Backblaze also lets you access individual files remotely. If you are traveling and urgently need a document or folder, you may be able to retrieve it without returning home. If a major disaster requires a full restoration, Backblaze can send a restore drive containing your data; after recovery, you return the drive.
Modern Macs Raise the Stakes
On many modern Macs, internal storage is integrated into the logic board instead of existing as a separate drive that can simply be removed after a failure. If a Mac suffers serious liquid damage, fire damage, or physical impact, recovering data can be difficult, costly, or impossible.
That makes a current backup more important than ever. The right time to decide how to protect your data is before a failed drive, broken laptop, theft, flood, or house fire forces the issue.
Trust, but Verify
I am a big fan of Ronald Reagan’s famous phrase: “Trust, but verify.” That single principle is absolutely central to a reliable backup strategy.
Do not assume a backup is working simply because the drive is connected or an app reports that it ran. At least three times a year, take a few minutes to verify that your Time Machine and cloud backups are current, confirm that external drives are included, and make sure you can actually locate and restore a file.
January 1 is an excellent date to begin this habit. Set recurring reminders for January, May, and September—or select any three dates you will reliably remember. A backup you have tested is a backup you can trust.
A Practical Setup
For most Mac users, MacMedics recommends:
- Time Machine on an encrypted external drive for fast recovery from accidental deletion, drive failure, and everyday problems.
- A second local or off-site Time Machine drive for added protection.
- Backblaze for automatic, off-site cloud backup.
- A third encrypted Time Machine drive stored securely and rotated periodically.
- A backup checkup at least three times each year.
No single backup solution is perfect. Time Machine is fast and convenient for restoring files or an entire Mac, while cloud backup protects against disasters that destroy or remove everything at one location. Together, they create a much stronger safety net.
Start Today
Fire may be the worst-case scenario, but flooding, theft, ransomware, accidental damage, and hardware failure occur every day. A solid backup strategy turns a destroyed computer from a permanent loss into a manageable inconvenience.
Protect your family photos, financial records, business documents, client files, and years of work before something happens.
