As part of my back-up strategy, I use DVDs. I create a regular back-up (monthly) using Macrium to encrypt my documents and important files. I also use DVDs for archival back-up. Every year, I back-up my pictures and documents because if lose access to my home primary data and back-up I would have to download all my data again, this takes time and will cost money. Given the size of photos, I use 7-Zip to split the archives into as many chunks that are required to fit onto disks.
Adding DVDs into the back-up mix creates a seperate media. So my data are not stored on hard drives, cloud and DVDs. I do not use USB drives for back-up.
In the creation window, I select DVD:
Remember to encrypt your back-up and store the passphrase in your password manager.
Once I have created the archive, I create a checksum to check the integrity of the file if I need to restore.
- Right-click on the file,
- Select 7-Zip,
- Choose CRC SHA,
- Click SHA-256 -> FileName.sha256 to create a checksum file.
Burn both to DVD using your favourite burning software.
