Frequently Asked Questions

How much backup storage do I actually need?

A good rule is to plan for at least 1.5 to 2 times your current data size. This leaves room for growth and for keeping a few older versions of important files.

Should I follow the 3-2-1 backup rule?

Yes. Keep 3 copies of your data on 2 different types of media with 1 copy stored off-site or in the cloud. This protects you against drive failure, theft and accidental deletion.

How often should I run a backup?

For business accounts and invoices, a daily backup is ideal. For home photos and documents, a weekly backup is usually enough, with an extra copy before any Windows reinstall.
