My external hard drive for data backup is almost full and I need a better system. How often do you actually test your backups to make sure you can restore files?

Test restore files regularly, a backup is only as good as your last successful restore.

I use a simple backup schedule with daily incremental backups to a local drive and a weekly full backup plus a cloud storage copy for off site safety. I test restores every month with a random file set and do a full restore drill every quarter to ensure everything still works.

One clean system that works for me is the three two one rule combined with a straightforward backup schedule. Keep three copies of important data on two different media and one offsite cloud storage. I keep hot data on a local drive that updates daily, archive older data to cloud storage, and stash a backup on a second external drive kept off site. This helps when a drive fails or a ransomware scare hits. For data backup you want versioning so you can revert to earlier states and you want to verify the backups by doing a test restore at least once a month. In a pinch you can run a rapid restore of a small subset to ensure the pipeline works without waiting hours.

Okay here is a practical approach you can actually use and not drown in options. Start by auditing what you actually need to back up and how often you change it. Then pick a better system than one giant external drive. The three two one rule again helps here and you can layer cloud storage for offsite redundancy. For the hardware side go for a larger external drive or a small NAS depending on space and budget. If you keep everything on one disk when that disk fails you are in trouble so you want at least a secondary location. Set up a backup schedule that covers daily or near daily changes with incremental backups and a weekly full snapshot. Enable versioning so you can recover from accidental deletes or data corruption. Encrypt sensitive files if security matters. For data backup a simple setup could be local fast backups plus an encrypted cloud copy that you update weekly. Use automation to run backups at night when you are not using the PC or laptop. Testing is where most folks fall short. Pick a test plan and stick to it. Each month pick a random sample of files and try to restore them to a test folder on a different drive. Note how long it takes and whether the restored files open correctly. Do a full restore drill every few months in a controlled environment to confirm that the entire chain from source to restore point still works. Keep an inventory of what you backed up and where and when the retention ends. Regularly prune duplicates and old versions to free space but do not delete things you might need later. If you can swing it move a copy of important stuff to cloud storage and keep the most recent set on a fast local drive for quick access. If your current drive is almost full consider moving to a larger drive or a small NAS and maintain a light weekly backup to the cloud so you have a safe offsite copy. It is not glamorous but it saves you from the panic of a failed drive or a ransomware hit.
