Secure your data before its too late!
Whether you use your computer for business or fun, you’ll agree that few things are more frustrating than losing data because of software problems, system crashes, or almost any other reason.
There’s no downplaying the importance of regular maintenance, no matter how insignificant some of those tasks may seem. If you give in to the temptation of ignoring the latest patch once, you could do it again. Before you know it, you’ve missed a year’s worth of patches or more.
What comes next are glitches, changes that aren’t recognized by the operating system, or a situation that’s so bad, your machine will need a clean install. Life is too short for that level of frustration.
Without further ado, let’s explore the 8 maintenance habits that can keep your data safe.
1. Back Up The System
It’s easy to reduce backing up the system to ‘saving data,’ but there’s more to it. Your system backups should help prevent or overcome the serious loss of data through equipment theft or a fire, the corruption of your data because of hardware issues, viruses, the accidental modification, overwriting, or deletion of important files.
You can only achieve that level of protection if you make backup copies of your data to removable media or a cloud service. A few options to consider include:
External SSD (Solid State Drive) — These days, external SSDs have replaced traditional hard drives for backups. They are significantly faster, more durable (no moving parts to break if dropped), and much smaller. When choosing an SSD, look for one that supports USB 3.2 or USB4 for the fastest data transfer speed The important thing to remember is that EHDs only offer protection to the folders and files you copy onto them, and they’re not immune to theft, fire, or flood. If possible, use an EHD that comes with backup software.
Cloud Storage – Cloud storage services such as Dropbox, Google Drive, and Microsoft OneDrive offer cloud space in which you can backup files, as well as the option of connecting devices to that cloud and accessing or sharing those files. The files you save in the cloud are stored in a remote location, which can offer an added level of protection.
Cloud Backup – Unlike cloud storage, cloud backup is software-based. After installing the software and launching it on your computer or laptop, you can choose the folders and files that you want backed up. When complete, the software will keep running in the background, and it will scan your computer regularly, uploading any changes it finds. If malware or viruses infect the system, you can access prior versions of files.
2. Secure Your Computer System
Ensure your Windows Firewall is active and your router’s firmware is up to date. However, the biggest modern threat isn’t just a “probe”—it’s Phishing. A hardware router won’t stop you from clicking a malicious link in an email. Use a browser with built-in “Safe Browsing” features and consider a DNS provider like Cloudflare (1.1.1.1) to block known malicious domains at the source. A hardware router won’t save your data, but it will help protect against data theft and system crashes.
3. Spring Clean Your Hard Drive
Hard drives can become cluttered in next to no time, which wastes space and affects disk performance. Your hard drive could be stuffed with hundreds of thousands of files in tens of thousands of folders, and most of them are likely to be browser cache files, duplicates, old versions of current files, and temporary and backup files.
Spring-clean your hard drive regularly to recover wasted disk space and to boost your computer’s performance. Start by clearing your browser’s cache and then Use the built-in “Storage Sense” feature in Windows 11. It automatically clears your temporary files and empties your recycle bin on a schedule. For a deeper look at what is taking up space, modern tools like WizTree or WinDirStat provide a visual map of your drive, making it easy to spot massive folders you no longer need.
4. Implement the 3-2-1 Backup Rule
The “Daily Disc” rotation is a thing of the past. Today, professionals use the 3-2-1 Rule:
- 3 copies of your data (Original + 2 backups).
- 2 different types of media (e.g., one on an External SSD and one in the Cloud).
- 1 copy stored offsite (Cloud backup is the easiest way to achieve this). Modern software like Backblaze or Acronis automates this by keeping “version histories,” allowing you to “go back in time” to a specific day without needing physical discs.
Back up each day’s work to the relevant daily disc and then back up the week’s work to the disc of that Sunday in the month. At the end of the month, back up the month’s work to the appropriate disc.
5. Update Your System Regularly
Make sure you keep your computer’s operating system and application software updated, especially if you use Windows, which is under constant attack from malicious software. You can use the Microsoft Update Service to keep Windows and Office up to date.
For other software on your desktop computer, keep yourself informed about updates, but evaluate whether you actually need them.
6. Smart Archiving with “On-Demand” Files
If you use OneDrive or Google Drive, use the “Files On-Demand” feature. This allows you to see all your archived files in File Explorer without them taking up space on your actual hard drive. They stay in the cloud until you double-click to open them, keeping your local drive clean and fast.
Data – This directory includes current or working data, which should back up daily.
Archive – The archive directory is for old data you do not need to access at the moment or in the near future. Back it up on removable options such as an EHD or DVDs.
7. Scan For Viruses Regularly
Even if you install a firewall or hardware router, don’t make the mistake of not running scans for viruses and malware regularly. You no longer need to run manual “weekly scans” if you are using Windows Defender. It provides real-time protection that scans every file as it is opened. Instead, perform a monthly “Offline Scan” (found in Windows Security settings), which reboots your PC and scans for deep-rooted “Rootkits” before the operating system even loads.
8. Update Your Passwords
According to recent cybersecurity data, Multi-Factor Authentication (MFA) is the single most important habit you can adopt.
- Use a Password Manager: Stop trying to memorize passwords. Tools like Bitwarden or 1Password create 20+ character random strings for every site.
- Passkeys: Whenever possible, switch to Passkeys. These allow you to sign in using your face, fingerprint, or PIN, making it impossible for hackers to “steal” your password because there isn’t one to steal.
- Stop Frequent Changes: Security experts now advise against changing passwords every few months unless there is a breach, as it often leads to people choosing weaker, predictable passwords.
Act Before A Crisis Hits
These 8 habits may look daunting, but they’re easy to implement, and you can do that in stages. With them, you can ensure you protect your data. Don’t act when it’s too late, as you may never recover what’s lost.
