Data is something a person or a business cannot casually replace. A cyberattack, a dead drive, or a natural disaster can wipe it out. A backup is how you get it back without starting over.
Ransomware
Picture a project locked by malware. An attacker may promise a decryption key and not deliver it. With a secure backup, you can restore the files and refuse the ransom.
Physical loss
Floods, hurricanes, and earthquakes can destroy the device that holds the only copy. Theft and hardware failure can do the same. One example is a backup server damaged in a break-in. The useful approach combines security and more than one copy, so one event does not erase the data.
Choices
- Cloud storage. Data kept online, off site, and reachable when you need it.
- Local backup. External hard drives, network-attached storage, or a server on site. These are reliable and fast to restore from locally.
- A hybrid of cloud and local copies, which adds redundancy.
On frequency, daily backups fit a business that handles sensitive data, and weekly or monthly backups may be enough for personal use. The aim is to lose as little time and as little data as possible.
Automated copies
Automated backup works like an autosave for the whole device. The software runs in the background. Benefits include:
- Protection when someone forgets to save.
- Recovery after a power outage.
- A way back after ransomware and other attacks.
How to set it up:
- Pick backup software or a cloud service that can run on a schedule.
- Set the schedule to daily, weekly, or whatever matches the need.
- Check the logs so you know the job is actually finishing.
Revisit the settings when what you need to keep has changed. Waiting until after a loss is the expensive moment to discover there was no copy.
