Backup & recovery, explained
A plain-language walkthrough of the core concepts behind reliable backup and recovery, independent of any single product.
Backup approaches
Continuous backup
Backs up new and changed files automatically as they occur, rather than on a fixed schedule.
Object storage backup
Cloud storage accessed through an API, often used as a destination for other backup software.
Version history
Keeps earlier copies of changed or deleted files for a period, letting you roll back to a previous state.
Local backup
Stored on a device you control, such as an external drive or NAS, for fast access and restore.
Cloud backup
Stored offsite with a provider, helpful if local hardware is lost, stolen, or damaged.
Full-system recovery
Restoring an entire computer's data after a major failure, sometimes via a downloaded archive or physical drive.
Building a backup and recovery routine
Identify what matters
List the files, folders, and systems that would be costly to lose.
Choose backup destinations
Combine local storage, continuous cloud backup, and/or object storage depending on your needs.
Let backups run continuously
Where possible, prefer automated, continuous backup over relying on manual runs.
Check backup status regularly
Confirm that backup clients are actually running and up to date.
Test recovery
Periodically restore a sample file or system to confirm backups are actually usable.
Plan for disaster recovery
Document the steps needed to recover critical systems after a significant incident.
Frequent backup issues
Backup client not running
If the backup application isn't running or isn't logged in, new files stop being protected.
Slow initial upload
The first backup can take a long time for large amounts of data, especially on slower connections.
Excluded folders
Some folders or file types may be excluded by default, leaving gaps in coverage.
Untested recovery
A backup that has never been tested for restoration carries hidden risk.
