Q: I don’t want to lose the legal files I spend long hours creating throughout my career. How should I back them up?
A: The short answer: Back them up frequently and automatically with multiple methods. Don’t rely on yourself or a single system.
Computers fail. There is no way around that. Hard drives crash. Viruses penetrate defenses. Thieves, storms, fires, and other disasters eliminate files and backups in your office.
Your first defense should be a reliable offsite backup. If you rotate backup hard drives offsite, you have a number of advantages:
- Protection against physical and technical disasters
- Really fast recovery with the right software and hardware
- Complete protection of files, settings, software, and Windows
But there are problems with rotating offsite backups.
First, in my experience, many small firms fail to rotate and test their backup drives consistently, day in and day out, year after year. Missing a single day can mean the disruptive loss of irreplaceable, valuable files.
Second, you stand to lose a day’s work or more if disaster strikes before your daily backup runs. Those current files may not be the most precious, but they are the ones you most likely want right now to get your work done.
That’s when you need an automatic, multiple-times-per-day, onsite backup. If there’s a fire, it will go up in smoke with everything else. But if you have server corruption, a drive failure, or an accidental deletion or file overwrite, it is great to have an accessible, frequent local backup.
Cloud backups can save the day by filling the gaps of other backup systems.
First, let’s eliminate the false fear about the supposed insecurity of “trusting my data to the cloud.” That fear would be legitimate if:
- You were to trust your data to an untrustworthy company.
- You relied exclusively on one company for offsite backup.
A reputable cloud backup company will give you the option to be the only person with the encryption key (password) to your backups. That option completely eliminates the risk that a wayward employee of the vendor will snoop around in your files.
Some people fear that modern encryption techniques “can be broken.” When you use a long-enough encryption key, not even the National Security Agency (NSA) can break into your encrypted backups.
As for the future, quantum computers promise to crack passwords of the lengths typically in use today. To be safe in the future, you can use an AES 256-bit encryption password of 44 alphanumeric characters. That means creating a 44-character password or phrase with numbers, uppercase, and lowercase letters.
Quantum computers of the future won’t be able to break a 44-character passphrase (256 bits of entropy), according to multiple sources.
But what if the cloud backup company suddenly fails? That’s why you don’t rely exclusively on one company. The best practice is to have two offsite backups. If one fails, you have the other.
