Continuous Online Backup, the patented system available with 365BackUp, is the best solution available because it means we are always watching your files and looking for changes. Whenever a change is detected, our continuous online backup engine immediately extracts the changes, compresses them, encrypts them, and securely transfers them to our data center.
Most online backup tools do scheduled backups. Scheduling means your PC has to be online and running when the backup happens at its scheduled time. For example, an administrator may set the backup to happen at 8:00pm every night. If your PC is shut down at that time, or your Internet connection is lost even temporarily, your online backup fails and you have to wait for the next schedule to kick in.
If you're busy working on your PC when the schedule kicks in, the backup will make your PC seem slow. Most people get frustrated and click "Cancel" - thus, another missed backup. Of course, you can always run the backup manually later. But that's just one more thing you have to remember to do - and that defeats the purpose of automatic backup..
Instead of one big backup at a pre-scheduled time, we do many tiny automatic backups throughout the day. Each little change you make is like a little offsite backup you'll likely never notice, because these smaller backups are incremental and happen faster. And since there is no schedule to miss, you will never miss an opportunity to have your files backed up, nor have to manually back them up.
