Frequently Asked Questions
Why DualBackup?
DualBackup is the best solution to back up your important files locally and remotely. With one configuration, DualBackup automatically backs up your files to local backup storage such as external USB hard drive and our backup servers in data center located in the United State.

There are two more reasons why DualBackup is your best choice for protecting important files:

Secure and Encrypted: Data is encrypted with 256-bit Advanced Encryption Standard on local backup storage and online backup server. Data is further encrypted with SSL when being transferred over the network. With two password protection, only you can access and know the contents of your data.

Easy to use: With explorer like user interface, it is easy to select and deselect files for backup. You can clearly view what files are being backed up. With one configuration, data is automatically backed up to both local storage media and remote data center located in the United State.

How secure is DualBackup?
Your data is encrypted with 256-bit Advanced Encryption Standard on local storage and online backup server. Data is further encrypted with SSL when being transferred over the network. With two password protection, only you can access and know the contents of your data.

Your data is encrypted twice before leaving your computer. Even file names and directory structures are encrypted. Data remains encrypted in both local backup storage and backup server. Encrypted data is downloaded into your computer and decrypted in your computer only. No one else can know the content of your data, not even our staff.

It is very important that you remember your passwords, especially your data encryption password. Without the data encryption password, your data cannot be decrypted. We can only help to reset your website access password and computer backup account passwords. Please note that we cannot get back your old password as your password is NOT stored in plaintext form in our database. We only store salted hash string of your password.

When does DualBackup back up my files?
You can choose to enable or disable automatic backup in the Schedule window. You can open the Schedule window from the menu (Tools > Schedule) or by clicking the Change Schedule link in Control Center. You can choose back up your files daily or just on certain days every week. By default, DualBackup starts at randomly selected time based on the last backup time. You can also specify the start time.

If a local backup was skipped because the local backup storage was inaccessible (for example, you didn't plug in the external drive), DualBackup automatically starts when the local backup storage becomes accessible. If a backup was missed because your computer was turned off, then next time you turn on your computer, DualBackup will automatically start after around 20 minutes.

What files should I select to back up?
You should back up all your important data such as your client information, documents, photos, and videos of your family. You may choose not to back up the program files and Windows installation directory as they are less important.
Does DualBackup create full backup each day?
A full backup is done at the first time,  and in subsequence backup, only new and changed files are backed up. DualBackup keeps a certain number of revisions of the backup. You can set the number of revisions for local backup from the General tab of the Options window. The number of revisions for online backup depends on the backup service plan.
Where are my encrypted files stored?
Your files are encrypted before leaving your computer. The encrypted files are transferred to our backup servers located in the United States using 256-bit SSL.
How long will it take to back up my files?
Local backup is fast which can back up 2 MB of data per seconds, and online backup speed depends on the network connection. With the concurrent transfer technology, DualBackup is fast, especially when backing large number of small files. The first backup may take longer time, and the subsequence backups will be quite fast as DualBackup only backs up new and changed files.
How to restore my files?
First you need to install the DualBackup software, then you specify the local backup location and enter the online backup account and password. With a few clicks, you can get your files back. Learn more >>
How long will it take to restore my files?
DualBackup automatically restore files from local backup storage and our backup servers. If a file is restored from the local storage, it is very fast. Typically you can restore files at 2-3 MB per second. If a file is restored from the backup servers, the restoring speed depends on your network connection. Restoring your files from the servers will be faster than backup. Usually the download speed of your network connection is much faster than the upload speed.
