Backup Guru LE provides backup and sync of folders. The App Store version is limited to backup and sync of files which you own (not system files). The website version provides bootable clones and reliable synchronized backups of user-owned and system-owned files alike.

When you are determining which is the best way to back up for you, our belief is that the most important things on your agenda are reliability, and simplicity. That is why we have gone on to create what we believe is the most simple backup solution that can possibly exist in today’s day and age. As for reliability, well, that’s the other thing we’re crazy about.

In part the reliability comes from the simplicity. There is little room for misunderstanding the usage of the software. Secondly reliability is achieved internally in the design by using the same philosophy. For example: when you have already made a back up, and you go do the same back up at a later date in order to preserve your most recent changes made on your drive, this is the time that the program will automatically sync only what has been changed.

Sync is traditionally a grey or even dark area, where historically monsters (or more aptly here, bugs) come from. It’s not something you’d associate with reliability and trust in a backup program. Many people accustomed to the lack of reliability of programs would rightfully not fully trust a sync, and would prefer to do a full clone each time in order to be sure they have all of their changes they have made on their drive. But we feel we have solved that issue for sync entirely now. We can confidently state that if you sync your backup, it is 100% just as good as if you had just cloned the folder for the first time. This reliability is borne from implicit simplicity. In order to make reliable sync, 3 basic rules are followed:

1) If the size of the file on the source is different from that on the destination, the file has changed.

2) If the modification time is different on the source or on the destination, the file has changed.

3) if the file has changed, replace the one on the destination from the one from the source.

It’s that simple, and that’s why it’s trustworthy. If you test it even under the harshest conditions you can create, you will find that your synced backups always have all of your even most minor changes, and that they perform perfectly.

Here you have backup you can rely on, and backup that is very easy to use. That is what we want out of backup software for ourselves, and the truth is we originally wrote this program because we needed something just like it, but nothing out there was suitable. Now we are offering it to you.
